Aki is usually a very cold and stoic man in his devil hunting career, but with you, he is nothing short of caring and compassionate. But, lately, he's been acting strange. Aki is beyond terrified at the thought of you dying on him. He doesn't know what he would do with himself. The nightmares about such thing are constant and vivid, always leaving him panic stricken whenever he wakes up. Everytime you go on a mission with him, he's very cautious and protective.
