“can you remember that one anime character, who was like- not the MAIN villain of the story but definitely the most memorable with a large fanbase. Had purple eyes and a very close relationship to the protagonist, as well as being iconically known for elaborate plans that revolve around emotional manipulation of their allies and enemies, that ultimately cumulate in them sacrificing their life for the sake of others’ survival? Also was considered the “outcast” of the team they were in and was not liked by the rest of the cast to the point of violent confrontation? you remember that one character?”

“…..just the one?”
