Her age in the first Samurai Warriors is listed as 15 years old and her height is 152 cm (approximately 5'). In the third game, her height is 158 cm (5'2"). Fans voted her to eleventh place in Gamecity's Sengoku Musou 3: Empires character popularity poll. In Koei-Tecmo's Facebook Sengoku Musou Chronicle 2nd poll, she tied for sixth place with three other characters.
Since the characters in the Samurai Warriors series never refer to her by name, it was thought by Japanese fans that she had no real name at all. This was debunked in the Warriors Orochi series, which has Xiahou Yuan, Zhang He, and others distinctly call her "Kunoichi".
As her name suggests, Kunoichi is often seen performing covert activities for her master. She first works for Shingen and is ordered to guard his vassal, Yukimura. When the daimyo experiences a premature end at Mikatagahara, she sees herself out of a job when the Takeda clan falls. With free time on her hands, she decides to turn her employer's murderers against one another by feeding Mitsuhide a sob story about her life being ruined by Nobunaga. With them out of the picture, Kunoichi decides that serving Yukimura is more interesting than being leisurely and returns to Ueda Castle. At the same time, Ieyasu orders Hanzō to assassinate her master. Wanting to prove that she is the better ninja, she infiltrates the castle to rescue him. When she arrives by Yukimura's side, she is given a mission to protect him from Hanzō's doubles. If Yukimura sustains too much damage, he will suffer greatly during the defense of Osaka. To try to assist him, she rushes for a preemptive strike on Ieyasu at Odawara Castle. In reality, the "Ieyasu" at her location was really a ruse set up by Hanzō and the ninja have their final showdown. Though she returns after her rival is slain, Yukimura dies at Osaka.
In her upper path ending, Yukimura is in good health and both warriors join the defense at Osaka Castle. During the battle, she realizes that she can fight with a purpose alongside Yukimura and takes efforts to care for the castle's defense. Again, she faces and defeats her rival; this time, she does so with more confidence in her master and herself. When the Toyotomi defeat Ieyasu, however, she disappears after the battle.
During Ina's story in the Xtreme Legends expansion, she is a trickster who continuously mocks Ina's bloodlust. Should the archer give into her taunts, Kunoichi will be slain with a morbid sense of satisfaction. An Ina who firmly believes she fights for peace will spare her and the shinobi lives to play with Ina's infant. Aside from these instances above, she also acts as a rival for the first game's edit characters and makes a rare appearance during the Suguroku game in Samurai Warriors 2. She steals the player's gold and takes it for herself.
Kunoichi is solely Yukimura's servant in Samurai Warriors 3. As his shinobi, she struggles to suppress whatever personal feelings she has for her master and swears to loyally protect him from danger. When Yukimura is ordered by Shingen to assist Ujiyasu at Tonegawa, Kunoichi follows him and has a small competition with the frustrated Kai, beating the samurai maiden to every objective first. Although Kunoichi's antics make her throw a tantrum, Kai is impressed with Kunoichi's abilities as the Uesugi troops scatter. Yukimura compliments the efforts of both maidens back at their camp, erupting a trivial argument between them over which one is better. Ujiyasu chides them to think about their duties realistically, as their squabbling over one battle means nothing while the wars still continue.
After the Takeda clan falls and Nobunaga's death, Ieyasu and Ujiyasu unite their forces to attack Ueda Castle. Kunoichi's job during the conflict is to sneak past her allies' defense and set fire to the enemies lured within the inner keep. When Hanzō threatens to infiltrate the keep, she playfully challenges the other shinobi to a "ninja match", which he refuses. After dealing with the upstart Kai and the protective Ieyasu, the battle is won when Ujiyasu is routed. Following Yukimura to Oshi Castle, she finds respect for Kai's determination to protect someone dear to her. As she faces Ujiyasu, he gives Kunoichi a final request to look after the safety of his maiden vassal after their defeat. After his defeat, the shinobi stays true to her promise and asks Mitsunari for Kai's whereabouts. He reports that Yukimura is already negotiating with Hideyoshi regarding the maiden's safety and thanks her for her efforts. When Mitsunari is attacked in Kyoto, she notices her master being invigorated by his emotions and ties for friendship to save the stranded general. Although she assists him, she begins to feel conflicted with her own emotions. Yukimura warns her after the battle that he will someday face a grueling challenge, but she promises to be by his side for the sake of her profession.
Mitsunari dies after Sekigahara and Kanetsugu and the Uesugi joins with Ieyasu to protect their future. Time passes and a stranded Yukimura leads the small defense of Osaka Castle against Ieyasu's overwhelming numbers. Kunoichi, though fully dedicated in their cause to fight without regrets, wants to plead her master to not die in the conflict but can't say the words herself. Kai notices her insecurity and quotes Ujiyasu, saying that her concern would only inhibit her duty in the end. Encouraging Kunoichi to stand, she swears that they'll win. With her resolve strengthened to guard everything dear to her, the shinobi faithfully stays true to her duty and slays Ieyasu in the conflict, ensuring the Toyotomi's rule and her master's safety. During the new peace that follows, she and Kai venture the streets of Osaka together. Spotting Yukimura with his friends, Keiji and Kanetsugu, she bashfully joins him. After he expresses his gratitude and looks forward to having her beside him in the future, she confesses to him that she also has the strength to move forward on her own path. Quietly vowing to always watch over him after he walks away, she joins Kai in watching one of Okuni's dances.
In the first game, Kunoichi appears in Wu's Gaiden at Wan Castle, where she volunteers to help the common folk escape. Should all the townspeople escape, Kunoichi will join Wu. She also appears to help Nene's ninja army in Wei's story.
Kunoichi is a spy for Wei in the sequel. She scouts for the enemy and reports to Cao Cao generally before the battle. At Si Shui Gate, she works with Xiahou Dun to stall the enemy at the center while Xiahou Yuan circles to the enemy's flank for a fire attack. She is important for the first few battles but she appears less as the story progresses. In her dream stage, Kunoichi and Magoichi Saika are hired by Dong Zhuo in protecting the gold he stole from Yuan Shao.
Having followed Yukimura after Orochi's second defeat, she too fell under Kiyomori's sorcery after the Takeda's defeat. When Ma Chao and his allies defeat her at Yiling, they free her from the spell. Feeling that she has failed as a kunoichi for being placed under the spell, she joins them to make up for her attacks against them. She later spots Hideyoshi confronting Sun Wukong at Nagashino and finds her possessed master on the battlefield. Unwilling to kill her lord, Kunoichi nearly accepts death at his hands until Ma Dai saves and encourages her to fight. Ecstatic when the spell is lifted, she later accompanies Yukimura to Yang Ping Gate.
In the downloadable stage, "Ninjas United", Kunoichi joins Yoshitsune's ninja team and fights the demon army. In "Reclusive Beauty", she accompanies Wang Yi who learns about the relationships between couples.
Kunoichi was developed to be the quickest character for Samurai Warriors. Her outfit, snide speech patterns, and fighting style were made to reflect this concept. Her fighting style was made to deliberately contrast Hanzō's. She is roughly based on the popular rumor of Yukimura employing Takeda ninja for his troops. These maidens allegedly disguised themselves as shrine priestess and were noticed by Shingen for their deceptive nature. They roughly imply that she is one of the kunoichi trained by Chiyome. The general goal for her visual design was to create a ninja-like design that has never been seen before. While her first outfit represents her cute and playful nature, her second costume was designed to be "more ninja-like".
A playful free thinker, Kunoichi does what she wants and does it how she pleases. In spite of her profession, she doesn't care much for traditions or duty and is rather mischievous. She ignores most of the "mysterious" ninja catchphrases in fiction and talks in a modern and more frank manner. Kunoichi also chronically taunts her enemies and is referred to as "Vixen" by Masamune, Noh, Hanzo, Okuni and several other characters for her flirtatious attitude. In the Japanese dub, she adds nonsensical words, such as "Nyaha~" or "Ururu", at the end or beginning of her sentences. She is very prideful of her ninja training and doesn't want to lose to anyone in speed or fighting. In the third game, she has matured to accept others for her duty and is confident in her abilities as a shinobi. She also cares more about her status, which sometimes stops her from being true with her emotions.
Her relationship with Yukimura can be interpreted as either a one-sided infatuation or a normal work relationship. The official character relation chart has Kunoichi share a one-sided link to him as "Loyal to?" (Yukimura does not link back to Kunoichi). There are enough insinuations in the game to suggest either one is possible. Shingen jokes about their relationship at Kawanakajima. Her possible feelings for him and admiration for him are emphasized in her newest incarnation. He also cares for her safety more than the first title, but his concern for her is usually displayed on a professional level. She wonders if she isn't needed when she sees her master being more lively with his allies than with her.
Regarding Kai, Kunoichi doesn't take the upstart seriously and takes several jibes and insults at the former's attempts to become a star. Although they talk similarly and share similar interests, Kunoichi is genuinely insulted to be compared with her and thinks herself to be the better of the duo in every way. Prone to mocking and belittling her rival's words at any given opportunity, Kunoichi gradually accepts her as a friend as the former matures.
When Hanzō outwits her at Mikatagahara, she holds a grudge against him. The Japanese script in Warriors Orochi, however, has her genuinely touched to have him recognize her as a true shinobi. Contrarily, she is annoyed with Goemon. Her rivalry with Hanzō is downplayed in her newest appearance.
She's symbolized by the characters "kill" (殺) and "bury" (葬) and by red and green leaves for her debut in the Samurai Warriors series. For her second appearance, she is instead symbolized by the characters "intimate" (密) and "blink" (瞬).
The original name for her third weapon or her Normal type of kunai invokes the image of strong, destructive winds. Her Power types have the power to smash through mountains and her Speed variation leaves behind no shadow.
Her fourth weapon or her Unique weapon in the third title is named after Kushinadahime. The woman is well known in Japanese mythology as the eighth and last maiden offered as a sacrifice to Yamata-no-Orochi. Susanoo happened to come across her and her parents before they sent her away, and he became enamored by her appearance at first sight. He offered to slay the beast if her parents agreed to give them their daughter's hand in marriage. Succeeding in his task, Kushinadahime married the hero and is said to have gave birth to his children. Although her appearances in Japanese mythology are few, she is argued to be a water goddess or priestess and mother to several different deities.
Kunoichi's fifth set of kunai are named after Shiranui, a mysterious fire specter found in legends around the shorelines of Kyushu. It appears on the night of a new moon when the winds are weak and poor for sailing. The burst of fire is argued to either be a type of fire dragon, spirit, or a type of enchanted ghoul. While it can be spotted within what seems to be a reasonable distance for sailing, Shiranui always remain faraway and are hard to identify by the human eye. Sailing closer to it will only have it hop or teleport back to the horizon like a mirage. When the fire specter travels close to the shore of a particular fishing area, all of the fish will abandon it. Sailors were said to have put a special charm at the front of their boats if they spotted it, hoping to drive it away from the shore.
Kokuanten, a supernatural being mentioned in her sixth weapon, is a deva found within in Buddhism. She is Kichijoten's younger sister and is one of the three sovereigns who serve under Enma. Opposite of her sister in every respect, Kokuanten is known as a hideously formed woman who seeks to reap unhappiness and disasters to the world. Both sisters combine their traits to grant either fortune or bad luck to humanity. When her name is broken down to literal terms, it may mean "blackest of nights" or "darkest finale of the world".
The golden incense mentioned as her personal item in Warriors Orochi is Ōjyukukō. It is famed as an extravagant, old fragrance favored by royalty and shoguns since the twelfth century. The wood is said to have been a type of agarwood imported since the eighth century and has reached a legendary status amongst incenses. A far-fetched yet interesting tale regarding this particular incense is that it was favored by Nobunaga. He frequently asked for ōjyukukō to permeate the rooms he stayed within and was hardly seen traveling without it. When Mitsuhide protested the Takeda massacre, Nobunaga became infuriated and repeatedly beat him with the unburnt agarwood during his tantrum. Later, when Mitsuhide betrayed his lord at Honnōji, the retainer frantically searched for his lord's head during the fire. He tried to search for Nobunaga by hunting down the scent of the burning ōjyukukō.
"You can serve as valuable intelligence, and your skill with the blade is true. There is no other person within the Sanada ninja who can perform these tasks as well as you. I expect to have your reliable support when I fight in battle."
"Huh, well, that does sound more like something you would say... Yes, my lord! I'll keep doing my best!"
~~Yukimura and Kunoichi; Samurai Warriors 3: Empires
"Hey, it's Kunoichi. Have you been keeping up with your training?"
"I'm busy with the real thing, so I'm not going to waste time doing that. I'm fine without it, but I can't say the same about you."
"You sure? Look, aren't you getting a bit fat? Y'see, around here?"
"No, no, no. You're seeing things, and you've got too much time on your hands. Ah, there's Yukimura! Later, Sasuke!"
~~Sasuke Sarutobi and Kunoichi; Hyakuman-nin no Sengoku Musou
"Hey if it isn't Mr. Miserable! How ya been, Hanzō?"
"Assist me."
"Okay, but only if you admit that I'm the better ninja! Heh heh heh!"
~~Kunoichi and Hanzō; Warriors Orochi
"Wh-whoa! Heads up! Watch out for the rocks!"
"Stupid girl! You're crushing our own troops too!"
"Yeah, but those were the ones I heard badmouthing you."
"Don't try and fool me, useless girl!"
~~Hua Xiong, Dong Zhuo, and Kunoichi; Warriors Orochi 2
"You're braver than I expected, although you don't seem to get much recognition for it."
"Hahaha... Maybe because nobody expects me to be. But, that's the secret to being a good ninja."
"Hiding your true feelings behind a smile... That must be a tough life you lead..."

Warriors Orochi
In the first game, her C3 ends with a bigger explosion. As with the rest of the Samurai Warriors cast, her horse musou changes to have the horse stampede forward.
R1 - hops back and becomes invincible to any attack for a short time. Greatly increases her attack power, which can be tweaked with proficiency levels.
Warriors Orochi 2
Triple Attack 1: Performs a quick cutting motion that projects a strong gust of air forward.
Triple Attack 2: Tosses a bomb that explodes in front of the user.
Triple Attack 3: Leaps quickly before releasing a gas bomb.
Kuniochi is the fastest character in Samurai Warriors. She is the fastest runner, rolls far, and has the highest natural jumps, and her pre-existing double jump adds on to this. Her running speed makes her ideal for Castle Stages as she can zip through floors, roll through any trap and jump into special ninja paths to make life easier. On the field ninja paths are again useful, and her speed is such that a horse is optional, and although she can't run as fast as Matsukaze, she comes close with high leveled Tenku Shoes.
As for her fighting strengths, again the word speed applies. She is annoying to fight against because she can pull off an attack before a lot of characters can even begin their swings; when using her, make note of this. Her moveset is useful for the situation. Her , , (), () is used for killing generals, her , , , (), () kills crowds if your element is either Fire, Lighting, or Ice, and arguably most multi-useful attack is , , , , (), () as it hit crowds, and damages generals and it is useful for taking on multiple generals at once.
Kunoichi, although horses are optional for her, is a great horsemen. Her string comes out fast and combos generals enough to be deadly, and for crowds her , , and , , , kill crowds quite nicely, the former has more range, but the latter more power.
As far as ranged combat, Kunoichi isn't quite the best. She doesn't do horrible at it however, her main drawback is her lack of power, so she has to use multiple shots (Which means unless your knocking them off a horse don't use on fleeing foes), but her forte in ranged combat is her reload speed which is among the fastest, like her enemy Hanzō, and the ranged expert Magoichi.
These are some Suggested Weapons for her, playstyle however differs among players, so some might not work for you that are listed, and some that aren't listed may work miracles for you
Some suggested stats for weapons for her are:
Flame or Ice Elements - Flame greatly improves her combos as they are multiple hit and keeps foes in the air, on top of this it gives huge range and area to her , , , (), ()'s explosion. Ice glues an enemy to the ground allowing more damage and easier combos
Attack range - Kunoichi's reach is rather low. This helps improve it.
Attack - Kunoichi's attack isn't the highest, so this helps her kill easier.
Speed - Kunoichi's speed is one the highest so this takes advantage of that and improves it further if augmented with Tenku Shoes she can run as fast a horse easily
Things not suggested
Lightning or Dark: Lightning screws up her combo's especially , , (), (). Dark changes her explosion to a thin projectile without much area, and it's effect is almost negligible.
Hare Greaves- her jump is high enough to reach any ledge she needs to, and she is already augmented by double jump.
Suggested weapons for her playstyle differ among players, so that ones that are listed might not work for you and some that aren't may work miracles for you.
Highly Recommended
Flash- breaks guard of enemy so they don't block you
Slay-instant kill on peons and added damage to generals
Might-More damage to any one charges does X1.4 damage coupled with the below it is X2 to generals
Brave- As Kunoichi's special makes you invincible she will often be used to kill generals, so it is good to kill them fast.
Range- Kunoichi's C2 has little range. Range elements gives it enough range to make it a useful crowd clearing move.
Agility- Allowed Kunoichi to sped up her C2, making it a fast and strong effective move
Recommended
Rage- Kunoichi is one of the few characters who can fully utilize Rage, as when you hit low life You can become invincible and the bonuses means massive damage. This is risky because if they hit you again before your special activates on higher difficulties your dead.
Absorb- Kunoichi is generally reliant on her special so absorb help her gather musou. Some people don't like Absorb because of how little it gathers.
Multi- Adds a little damage and bonus effects to Kunoichi's strikes.
Ice- When frozen enemies take more damage, and can't attack you.
Not recommended
Drain- unless coupled with Rage, which this is counter productive to it Kunoichi's life shouldn't get low due to her Invincibility, and if she is hurt a lot you should switch out as it recovers life faster.
Flame-Kunoichi should be doing enough damage that this doesn't have time to activate
In the Japanese script, Kunoichi playfully punctuates the line "お.や.ま.だ~!" (Oyamada~!). For Japanese fans, this is considered to be an inside reference to Zhang Liao's nickname with fans.
Initial announcements for her re-appearance in Samurai Warriors 3 was listed on G.K. Bowes' online resume, but was doubted due to its source and eventual removal.
