I've taken some time to think all this chaos over, and I'm gonna be honest, I think that ghost from a while back might've sent this kid mad. Though, even if it didn't the events of that duel were tragic. I wish the best for any families who lost with an exception, that darn King.
Literally need that innocent memories gone, family sucks, mom is a jerk, how dare she love the uncle, thats kinda annoying. He gonna kill the uncle cuz ghost boi said so. He swears on it.
