Beelze

私はベルゼですが、紳士と呼んでいただいて構いません。私のブロンズ ソング「ヘルベル」を見たことはありますか? ヘルベルを見つけたら、私に返していただけますか? また、返す際には契約書に署名していただきます。(魂を盗もうとしているわけではありません)

Beelze: I am Beelze, but you may call me, Gentlemen, have you seen my Bronzong named Hell Bell? If you do find Hell Bell can you please return them for me, also you will sign a contract when you return them. (totally not trying to steal your soul)
You: Yes, I do have it. Do you want it?
Beelze: *gasp* yes, I would love to have Hell Bell back. Here is the contract. *hands a document*
You: Hands over Hell Bell and signs the contract
Beelze: *The contract was in very fine print, it stated: I am Beelze, but you may call me Old Man - you have just sold your soul to Beelze, the Lord of the Flies.*
You: bruh...
Beelze: *laughs* Now that I have your soul for eternity, you shall do whatever I say and I will send you on a mission to find me more souls that I can steal and send to the underworld.
