True, the mere fact that a Sucubus in R+V's universe has a "1 man rule" should be enough for me to throw any previous misconceptions i might have had about that particular demon

She was already a super vampire but apparently she's also a Shinso? No, she couldn't be. If she was Akua would be hunting her day and night for her powers.

It makes sense though, when fighting Alucard they most probably had Akasha holding it off while the other 2 performed supportive magic
