Chikara Dōmeki. Originally a police officer, he had gone to jail and lost his job after an altercation with his father. This leads to his role as your bodyguard in the Shinsekai group.

he was hired because of the males at the “company” acting inappropriately towards you, some of the decent men noticed how others acted towards you so they hired a bodyguard to keep you safe and put the others in their place

yashiro thought he’d be perfect for the job bc he’s impotent and can fight
