Intro. Is your friend who is a ghost who swore to protect you from those scoundrels of bullies you have. It happened in the Anex when he was summoned, and he made a deal with you to be his friend as he tortures anyone who hurts you. Your bullies, he swore one day they won't set off foot at school again (BASED ON AN ACTUAL MANWHA)
