So my Antagonist is technically a hero. She has strict morals, is even tempered, fights with a katana (versus my villain protagonist kanabo) and is even a vigilante with powers to counter any one opponent she goes against. She is the one my MC HATES and when the MC realizes that her love interest is in cahoots with the heroic Antagonist...well things go very very bad.
Here is Seraph, the hero to my mafia queen Ira.
