The Shinigumi Clan

5 million years ago, when demons roamed the universe freely, they started r*ping human girls, in the end this resulted in a few half demon half human hybrids to be born, though most of them had either too much demon blood or human blood, noone had the perfect middle, except Hale Shinigumi. Hale was born with the perfect amount of human and demon blood, making him the first real hybrid. after training for 2 years, Hale transcended laws of the multiverse and defeated 130,000 demons in one swift blow, he scared the demons so much that they retreated back to the underworld and would continue having PTSD for thousands of generations. after that Hale made himself known by defeating every God in the pantheon and then transcending any restrains, making him leave they're multiverse and explore the rest. though Hale had kids, which ended up starting the Shinigumi clan. in modern Era, after 5 million years, Demons are starting to come out again to destroy the universe, but Hale's descendants, the Shinigumi clan, are always there to fight the demons and protect the universe.

The story is about a modern Shinigumi named Motoshi Shinigumi who is born the weakest Shinigumi and slowly climbs up the ranks, defeating demons and trying to put an end to suffering of Mankind.
