Himiko Toga

Himiko Toga (トガヒミコ) is a villain affiliated with the League of Villains and part of its Vanguard Action Squad. She and the rest of her team serve as the main antagonists of the School Trip Arc.

Appearance
Himiko is a slim, short girl with blonde hair, which she wears in messy styled buns on either side of her head. She also sports straight bangs, cut in an uneven hime cut-like style, and two stray strands of hair on each side of her face. Her eye color is yellow, with vertically slitted pupils and dark circles under them, and she has pronounced, cat-like canine teeth.

She wears a sailor uniform with an oversized cardigan that covers most of her skirt, and cuffs that cover the palm of her hands. She also wears knee-length black socks and classic Japanese school uniform shoes. In her right pocket she carries what appears to be a number of charms on either a keychain or a cellphone.

Personality
Himiko's dominant traits are her constant blushing and smiling. She is a very cheerful girl, to the point of smiling even after having presumably killed someone, displaying her apparent sadistic tendencies. Even when danger is imminent, as when Tomura was about to attack her, Himiko continues smiling. She's also frequently seen blushing, though seemingly out of excitement rather than embarrassment, giving her a permanent somewhat lovesick look on her face. Himiko has also shown to be insane.

Himiko finds life to be difficult and wants to make the world an easier place to live in. She looks up to Chizome Akaguro and sees him as her role model; however, at the same time, she has declared a desire to kill him.

History
Himiko is a suspect on the run for serial blood draining murders. After Chizome Akaguro's backstory was revealed to the public, Himiko became inspired by Chizome and decided to join the League of Villains.

Field Training Arc
Three days after Stain's defeat, Himiko is seen blushing excitedly after presumably murdering someone.

End of Term Test Arc
Himiko along with Dabi are scouted by The Broker who brings them to the League of Villains to be introduced to Tomura Shigaraki. At the hideout, Himiko expresses interest in joining them.

When Tomura becomes displeased with his visitors he orders Black Mist to send them away. Black Mist asks Tomura to be patient and listen to what the visitors have to say because they were scouted by The Broker. The Broker agrees with Black Mist about letting the visitors introduce themselves. The Broker tells Tomura that the girl is a suspect on the run for serial blood draining murders. Himiko introduces herself to Tomura and explains that life is difficult and as a result, she desires to make the world an easier place to live in. Himiko wants to become someone great like Stain and excitedly pleads with Tomura to let her join. After Dabi's introduction, Tomura becomes angry at Himiko and Dabi for constantly talking about Stain and prepares to attack them; Himiko and Dabi also prepare to defend themselves. As the three clash, Black Mist uses his mist to warp Dabi, Himiko and Tomura's attacks away from each other, which stops a potential fight. Tomura storms out with Himiko commenting that she thought she would be killed and smiles about it. Black Mist asks the broker to wait a few days for their reply regarding Dabi and Himiko's registration into the League of Villains.

School Trip Arc
Days later, Himiko was seen along side Dabi and the rest of the Vanguard Action Squad were looking over the Yuuei camp site. When she expresses her dislike for the mask she's wearing, she's informed that the equipment functioning properly is the only thing that should matter to her. On the night of the third day, the Vanguard Action Squad attacks the training camp; Himiko appears behind Ochako Uraraka and Tsuyu Asui and attacks them.

Having managed to slightly wound Ochako’s left arm, Himiko explains that normally she would have to make a big wound and suck blood with her mouth directly. However, thanks to her machine, her Quirk’s weakness is compensated by the machine’s ability to drain blood from tiny wounds. Himiko begins to attack, to which Tsuyu responds to by flinging Ochako away with her tongue. Tsuyu tells Ochako to run back to the facility and call for help and says that she also plans on retreating with her. Suddenly, Himiko manages to wound Tsuyu’s tongue with her knife. Tsuyu tries running away, only for Himiko to pin her hair to a tree with her machine. Himiko prepares to drain Tsuyu’s blood, however, Ochako arrives to Tsuyu’s aid which causes Himiko to turn her attention to Ochako. Himiko attacks with her knife, only for Ochako to dodge. Ochako uses the martial arts skills she learned from Gunhead to apprehend Himiko.

With Himiko on the ground and apprehended, Ochako tells Tsuyu to restrain her arms. However, Himiko begins talking to Ochako, calling her spectacular while noting that they are similar. Himiko says that they are in love with someone. Himiko tells Ochako that she knows how she feels because they both are girls; Himiko begins talking about people who are in love strive to be like the ones they love. Himiko’s talking enrages Ochako. Himiko notes that love stories are fun and uses her machine to stab Ochako’s leg, who was unable to stop her due to being caught off guard with Himiko’s talking. Himiko begins draining Ochako’s blood. Suddenly, the Bakugou Escort Team arrives and sees Ochako. Himiko stops draining Ochako’s blood and pushes Ochako aside, not wanting to engage a large group of enemies and not wanting to die. Before retreating, Himiko sees Izuku and blushes. Himiko retreats with Ochako wanting to follow her, but Tsuyu stops her due to Himiko’s Quirk being largely unknown.

Eventually, Compress captures Katsuki and orders the Vanguard Action Squad to regroup at the rendezvous point. Himiko arrives at the rendezvous point with Dabi asking how her mission went, only for Himiko to reply that she could get the blood of one person. Twice is unimpressed and wonders why Himiko is excited, to which Himiko replies that she found a boy she is interested in. As Himiko and Twice converse, Dabi orders them to keep quiet.

Dabi sees something approaching them;  Izuku, Mezou and Shouto smash Compress onto the ground and then apprehend him. Dabi is seemingly displeased while Twice contradicts his knowledge about the identity of the Heroes.

Quirk and Abilities
Unnamed Quirk: It is suggested that Himiko's Quirk gives her the ability to drain blood from her targets with the use of her mouth (possibly through her fangs). However, the weakness of this Quirk is that her victim needs a wound serious enough in order for her Quirk to work.

Equipment and Weapons

 * Butterfly knife
 * Blood Draining Machine - Himiko's machine allows her to drain blood from even the smallest of wounds, which compensates her Quirk's weakness.

School Trip Arc

 * Ochako Uraraka & Tsuyu Asui vs. Himiko Toga: Undecided

Stain
Himiko was inspired by Stain and harbors an unhealthy obsession towards him. Himiko has stated she wishes to become Stain as well as to kill him. Her desire to make the world a better and easier place to live in is likely influenced by Stain's ideology or she was inspired by Stain's method of accomplishing his goal.

Trivia

 * She's the first character in the series to have her name revealed in katakana rather than kanji. This was likely done to avoid hinting at her Quirk.
 * Her respirator appears to be inspired by Bane from the recent Batman movies.
