Differing from his normal self who abhors the image of Dracula and wishes to wipe away the disgrace it caused him, Berserker embraces it to become "an avatar of calamity who uses his vampiric powers without mercy." He still resents the idea of being summoned in such a state, but he will generously work together with a Master so long as they did not deliberately summon him as Berserker. Although he can converse properly despite his high level of Mad Enhancement, he requires a truly exceptional Master, else he will quickly make to suck their blood. He will hold their relationship as that of between a king and retainer until the bitter end.
