Characters of Yondemasu Yo Azazelsan. Page in construction, contributions are welcomed.
Akutabe is a detective that specializes in using demons. He is very knowledgeable in the occult, and uses this knowledge to overpower the demons, even enabling him to block a powered up "divulgence" spell from Beelzebub. He is Sakuma's employer as well as a mentor. He will summon demons to do his bidding and will often mistreat them if they annoy him or mess up their assignments. He is shown to be cruel and rather sadistic, causing even demons to be afraid of him.

His powers range from making people attractive, unattractive, and even cause impotence. When Akutabe ended their contract, he became contracted with Sakuma much to her chagrin.

However, Azazel ruins his opportunity to improve and show that he's changed, and pretty much screws up whatever task is given to him. Incubus does his job for him and is presented a proper sacrifice. Azazel, however... is given a cube of fat. Rinko tells the visitors that he's been having that sacrifice for a long time, making it succinctly clear that Akutabe's offices are done with him and will not have any of his shit, if their treatment of Incubus didn't make it anymore clear. His mother and Kiyoko are horrified and pretty much disown him when he eats it in absolute shame. He even sheds a tear. And he had every second of it coming.
