The Traitor.

Joester teleports to Yana. 

Joester: According to the contract, you now need to help me. 

Yana: How can I help you ? 

Joester: You have to kill Edward. 

Yana: What the ? By no means, after killing Henry, do you want me to kill Edward !?

Joester: I didn't kill him, but other people who had a contract with me. 

Yana: Well, I won't accept. 

Joester: So you don't accept? 

Yana: Yes, I will not accept. 

Joester: Okay, for disobedience you will be locked up in the the traitor's prison.

Yana: What prison? 

Joester: I'll lure Leo and Sokka to your rescue, and I'll have the other 3 killers killed to kill Edward! 

Yana disintegrates and all her clothes and belongings remain in the normal size, while Yana is teleported in the size of the traitor's prison because she did not submit to the contract. 

* AUTHOR'S NOTE - A GHOST CAN MAKE WHAT CONTRACT SHE WANTS, BUT IF THE MAN DOESN'T ASK TO SEE WHAT KIND OF CONTRACT IT IS, THE GHOST CAN ASK FOR ANYTHING * 

Joester in his mind: In order to lure Sokka, I have to lure Leo, and Leo will ask Sokka for help if he wants to resign, but how? 

Leo calls Yana 

Nobody answers. 

Leo: Hmm, weird. 

A week later. 

Leo: Haven't you seen Yana these days? 

Roy: No, why ? 

Leo: Well, I keep calling her and no one answers. 

Roy: Come on, try calling again !

Leo: Okay !

Leo calls Yana. 

Someone answers. 

Leo: Yana ?

The killer: Hello.

Leo: Who are you and why do you have Yana's phone? 

The killer:If you still want to see Yana come to the center of Sendai in the abandoned school, you will find her because there is only one abandoned school in Sendai. 

Leo: Why did you take Yana? 

The killer: Come and find out! 

The killer hangs up

Leo: Fuck !!

Roy: Was Yana kidnapped? 

Leo: Yes.

Roy: What did he tell you? 

Leo: He told me he would be waiting for me at that abandoned school in downtown Sendai. 

Roy: We need to see what they want, we need to talk to Edward and Mirai. 

Leo: You're right, we need to find out what they want from us.
