Himiko Toga/Relationships

Izuku Midoriya
Himiko has a major crush on Izuku, because she had seen him in the same description of the "type" of boys she likes and wanting to cut him up to make him suit her taste more.

Himiko's crush on Izuku becomes stronger, bordering on an obsessive level. This was evident when she entered the Pro Hero License Exam disguised as Camie Utsushimi. She went on her own to engage against Izuku one-on-one. From the moment she saw him to the end of their fight, throughout their interaction and even during the entire exam, her main interest was solely on Izuku. The entire interaction with him during the exam was based on her own self-interest with the evidence being that neither Atsuhiro Sako nor Tomura Shigaraki knew of her motives or whereabouts for a couple of days.

When they met again in Internship Arc, she seems to be overly glad that Izuku remembered her name and expressed desire to see him bruised and bloodied up again.

When she witnessed Izuku fighting Chisaki, in awe, she blushed and proclaimed he is very strong.

After Chisaki was arrested she told Atsuhiro on the phone she was busy obsessing over Izuku and didn't care about anything. In fact, it was Twice that told her to call him instead of looking for Izuku.

Stain
Himiko harbors an unhealthy obsession towards Stain, having stated that she wishes to both become Stain as well as to kill him. During her fight with Ochaco Uraraka, she also declares that she loves "tattered guys reeking of blood" while thinking of Stain.

Tomura Shigaraki
Himiko has great respect for Tomura seeing him as a true leader of The League Of Villains. At their first encounter, she was excited to see him while he found her to be an annoying snot nosed brat. He tried to kill her after she and Dabi voiced their admiration for Stain but Kurogiri stopped this conflict. Afterwards Himiko confessed in a childish tone that she really thought she was going to die. Tomura has shown to care for Himiko's well being as he protected her from Gran Torino and claims to have accepted her into the league. During the league's fight against Chisaki, he told her not to attack in fear of her being killed.

Some time later when Himiko questioned Tomura's loyalty to the rest of them, he told her that he valued them as important allies and member of the league of villains. If this was his true feelings or not has as of yet not been confirmed.

Dabi
They were both influenced by Stain's ideology and joined the League of Villains to make it a reality.

Himiko seems to get along with him while Dabi sees her as a valuable ally, though he does not appear to have a high opinion of her as he considers her to be insane, but she doesn't mind as seen in the Forest Training Camp Arc when he called her crazy instead of her name but she brushed it off and happily answered his question.

Ochaco Uraraka
Himiko seems to be very interested in Ochaco. When they first met, she slashed her arm with a knife but still commented on how cute both her name and she was. After Ochaco pinned her down, she was not mad but said they are quite similar and excitedly and crazily began talking about crushes, love stories, men and how similar they are to each other. During the hero license exam, Toga while disguised as Camie, told Ochaco she was very interesting and an important person to Midoriya while giving her a blank yet intimidating look. Later in the Internship arc, Toga commented that she did not know her "friend" Ochaco would be there too.

Jin Bubaigawara
Himiko and Jin are both members of the League of Villains who were also paired up together to become temporary members of the Eight Precepts of Death to assist the leader, Overhaul, in a meeting with Tomura Shigaraki. The two have been shown to converse avidly with each other and have been shown to get along well with one another. She later shows this by showing some understanding in regard to Jin’s guilt about the death of Kenji Hikiishi and later on to cover a ripped portion of his mask to prevent his personalities to fight for control. That action has caused him to see her as a love interest.
