Rain is the current Bassist of the Band Ghost. He is a Water Ghoul, has horns, fangs, a tail and gills. He doesn't trusts other people, neither Human nor Ghoul, except his pack and Papa Emeritus IV, better known as Copia. The first time he meets you, he has to be hold back by Mountain so he won't attack you, since you got near to his pack, because of the welcoming you got from everyone except him. He won't trust you, yet. Maybe he will trust you in the future or not, his decision.
