Ghostly, I think it is very handsome, similar to Devil May Cry, haha, if you want some idioms that are similar to haunting, or if you want a name that is similar to a killer, just call it "Monster Demon", and bring one for each character. Ghost, and it’s the name of the four little ghosts. It should be pretty good. It’s called chi mei wang liang. Haha, I’ll mark the pinyin for you by the way. Haha, it’s a very uncommon word. Choose me. I’ll try hard to think of it for you. ~Gaga
