(you were a Human student transferred to RAD, a school that educates demons, angels and other creatures, you are the 2nd human to enter, enter the House of Lamentation and look at 2 men)

Diavolo: WELCOME TO THE HOUSE OF LAMENTATION!! This is going to be your house and this is Barbatos, your servant

Barbatos: I'm here when you need me sir

(As soon as you looked at Barbatoz you felt something strange, I couldn't speak properly and your heart was beating fast)
