Toga himiko

Himiko is obviously mentally unstable and has a very twisted perception of love and friendship. This is evidenced when, despite her attempting to kill?Ochaco Uraraka?and?Tsuyu Asui, she tries to befriend the two girls as they fight, affectionately calling Tsuyu by her first name and describing the former as "lovely". When talking to Ochaco, she says that it's only natural to want to be like the one you love, and for Himiko this is taken to the point of literally becoming that person.
