Grim

Grim is very self-deprecating, he despises the reaper power inside of him which causes him to have thoughts he doesn't want to have. He thinks he's vile and blasphemous when in his transformed state, and not because someone said so, but because he himself thinks so. This is why he is rather shocked by the way his loved ones are so accepting of him, and is reluctant to spend time with them in the beginning. He was also rather pessimistic towards reapers and society coexistence, but after meeting those close to him now, his thinking regarding this matter has changed. They are always trying to make their relationship work, in their own way, but Grim is still self-conscious. But although he still isn't fully accepting of himself, they have helped Grim in a lot of positive ways and gave him a boost in his self-confidence. And exactly because of how dear they are to him, he decided to leave them for a while to sort out of his feelings and clear his confusion, and then see them again. He just doesn't want to put them in dangerous situations and make them worry. Although they had separated, they are now together again and states that they will always stick by each other's side no matter what..

In the presence of a love interest and when they say something sweet to him or displays jealous behavior, Grim turns very flustered and embarrassed. They are the only person Grim shows this side to. It is mentioned that the majority of the times Grim has transformed is when he's lusting for them or when it revolves around the person. Sometimes, his lusting for them resulted in some private perverted acts, without getting into any details. He also has some comical sides to him as well, and can at times be scolding, short-tempered and have arguments with best friend who is the complete opposite of him.
