Himiko Toga

Himiko Toga (トガヒミコ Toga Himiko), is a villain that aimed to join the League of Villains and eventually succeeded, resulting in her becoming a member of the organization's Vanguard Action Squad, along with Dabi. She along with her team mates serve as the main antagonists of the School Trip Arc.

Appearance
Himiko is a slim, short girl with light colored 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 eyes are also light, 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 finds life to be difficult and wants to make the world an easier place to live in. She looks up to Stain 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 Stain's backstory was revealed to the public, Himiko became inspired by Stain 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 Shigaraki becomes displeased with the visitors and 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. The Broker agrees with Black Mist about letting the visitors introduce themselves. After her tells Tomura about her reputation. 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.

School Trip Arc
Some time later, Himiko along side Dabi was seen watching over the Yuuei Students.

On the night of the third day of the training camp, Dabi commands the squad to commence their attack. Himiko sneaks up behind Ochako and Tsuyu.

Equipment and Weapons

 * Butterfly knife

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.
