People he's met so far:
Hibari - A highly uncommunicative god-demon being thing. Doesn't seem too terrible apart from his abrupt manner.
The Chef (NPC) - Like Hibari. Rin enjoyed working with him though, on Night 26.
Merrow the Space Pirate - Strange girl.
Vivi - Hesitant fellow. Rin likes him. Taught him how to cook on Night 26.
Mercury - Bossy girl who is often misunderstood. Could possibly get along with her.
Jendayi - Seems shy and vulnerable at first, but she's quite friendly once you get to know her. Rin is determined to protect her whenever possible.
Tarzie - A little doll. Doesn't know much about him yet.
Saguru - Very knowledgeable teen detective. Rin is impressed.
Rose (NPC) - Possibly a fae/fairy thing. Some guy called David tried to explain but Rin is just more confused. She seems to find murder enjoyable.
