Shoukan Suru Sekai
I have to say this: oh boohoo Kaido lost his parents, AT LEAST HE HAD THEM TO LOSE UNLIKE TOKOYO, like I'm sure the story will give an explanation why he's parentless but currently Kaido is a bitch
and he hates the summons because the are forcibly or unknowingly being summoned to their world, ripped from their homes and and maybe their families, and placed in a completely new and odd environment and are most often met with hostility and when they react to that hostility it's their fault because they're the odd ones out? honestly suck an egg, Kaido
