Himiko Toga is a villain from Boku no Hero Academia. She joined the League of Villains along with Dabi.
Himiko is jubilant and charismatic. She is seen with a smile most of time and have a joyous expression. She also have a carefree nature to her as seen by how she does not mind calling someone she fights as a friend like Ochako Urararaka. Himiko is also sadistic when she takes pleasure from taking blood from Ochako in her battle. She also have a crush on Izuku Midoriya and seeing him as attractive. When she saw him after his fight with Muscular, she remarked on his beaten up appearance as something that is attractive to her. While she is carefree and happy at most times, she has a surprisingly violent personality as told by her crimes which involves murder and her desire to kill the Hero Killer even though she likes him.
Himiko first appeared at Tomura Shigaraki's base with Dabi as new recruits to the League of Villains. Tomura was not impressed by their praise of Chizome Akaguro. Tomura tried to attack them out of spite but his attack was deflected by their moves. Despite Tomura's hostile encounter, they were accepted into the League of Villains.
Himiko later appeared with a few other villains in the Vanguard Action Squad. Their objectives were to attack the Yuuei students at the camp while they trained. During the attack, Himiko encountered Ochako and Asui. She had a device that was being used to take blood from her targets. As the fight continued, Himiko held a conversation with Ochako about a crush that she had. As the confrontation continued, Himiko retreated in the woods as the other Yuuei students came to their location. As she left the scene, she glanced at Izuku in his beaten up appearance from Muscular and blushed. She made it to the exit point of the forest where she waited for a villain to bring Katsuki Bakugou with them. Black Mist appeared and he was able to help the members of the Vanguard Action Squad retreat from the scene and capture Katsuki.
They kept Katsuki under them intending to make him join the League of Villains. With the help of the heroes and the U.A students, they were able to retrieve Katsuki from the villains. All for One also transported the villains out of the way to deal with All Might.
Himiko later took the DNA of a girl called Camie to infiltrate the U.A students during the Hero License Exam so that she could get close to Midoriya and obtain his DNA. After getting his DNA, Himiko went back to the League of Villains without getting caught.
