Haku

Leo and Minoru sit next to Edward and talk: 

Edward: Thanks. 

Leo: We should thank you for everything you did, if it weren't for you we wouldn't have been able to stop Joester, only you could have killed Gluttony, and so could Wrath. 

Minoru: I'll go to the bathroom. 

Leo: Okay !

Minoru enters the bathroom and washes his face suddenly on the mirror he sees someone who was behind him. 

Frightened Minoru returns and asks: 

Minoru: What are you doing here and who are you? 

Haku: I'm Haku, I've seen you before and that's why I decided to come to you, you have an ability that very few people have, you can see ghosts and that explains how you saw me. 

Minoru: Are you the ghost that has the power of an SSS ghost? 

Haku: Well, yes, I appeared recently, I was human, but I was cursed by someone who makes me stay after Wrath.

Minoru: ND probably cursed you. 

Haku: I want to team up, I want to be human again. 

Minoru: Huh ?

Haku: Although I have great strength in me, I feel weak. 

Minoru: Come on, I need to introduce you to someone. 

Minoru comes out of the bathroom, and Haku comes after him. 

Minoru: Leo, this is Haku, the mysterious ghost unrecorded by the presence of an SSS ghost.

Edward puts on glasses to see ghosts.

Leo he gets up. 

Leo: Haku, are you on our side? 

Haku: Somehow yes, I want to be human again, and your enemy could be the one who made me human. 

Leo: Can you tell me about the other ghost of SSS rank? 

Haku: Ghosts can contact other ghosts, but I can't do that right now because I haven't adjusted to my powers. 

Haku: Okay, then we'll team up, we really need a ghost. 

Edward: I'll make Henry and Mirai keep an eye on you, I'm weak in the moment, but Henry or Mirai will handle you. 

Haku: Okay, I'm not going to hurt anyone. 

What does Haku want to do?
