OKAY. Daddy is a shinigami belong to SS. Comes to Earth and ppl no see daddy, no?? Maybe gigai or gagai that thingy and become member of earth's society. But do gigai or gagai have sperm if yes, whose sperm is it?? When daddy comes back to shinigami form, do he leaves anything behind, like a gagai or gigai. Maybe its explain in the manga but i only watch the anime.
1 more thing, why japan?? do shinigami dont fight hollows in germany too?? I dont know if they keep fighting hollow in the manga but im getting tired with the anime. I know they're dealing with vizard now and aizen next.
