Adam = Oetsu Nimaiya from Bleach; VA Youji Ueda Lucifer = Hound Dog from BNHA; VA Eiji Hanawa Vox = Twice from BNHA; VA Daichi Endou Alastor = Gus from FFVII: Rebirth; VA Setsuji Satou Sir Pentious: Dekapan from Osomatsu-san; VA Youji Ueda

By the way you're doing yourself a disservice by not watching this clip of Gus's intro in FFVII: Rebirth. If for no other reason than to imagine Alastor inexplicably in Gus's position lol youtu.be/pB_ri1NRP7g?...

Pentious and Adam share a seiyuu, so I chose two different characters he has voiced for them both.
