   Summary

   Hachiman Hikigaya wakes up(Isekai) into another world similar yet so very different from his own where everyone has animal traits(Ears, tails, or wings) from canines, cats, monkeys, bears, deer, horses, and reptiles. He learns that he is not a Hikigaya and his 'father' was his sensei; Hiratsuka! A 'Father' that didn't know about him, just like all of his former connections.
