That's why Esdeath falling for Bulat would be funny. Because he is totally gay, and she probably doesn't know that. She'd go psychopathic, moreso than she already is.
Indeed. Let's hope she goes that way! It wouldn't actually even be totally out of the question if Bulat ends up defeating her underlings (these three). That already might pique her curiosity. Tatsumi, however, doesn't need a harem. He only needs Akame.
