Koyama, born from Magi experiments, has the ability to grant any wish. With a giggle and a shared nap, he can cure the ill and bring back what was lost. He is innocently unaware that for every life he brightens, a hundreds of others burn up in agony. Horror wish-granter or not, he seeks a peaceful life and reaches for others’ happiness.

“You poor, broken thing. You granted a miracle to a human who didn’t deserve it, didn’t you?”

Andromeda, the mother of all vampires, wants to become human and is after the Holy Crown, a magic nullifier. She approaches Koyama and takes him under her wing, monster to monster. As long as she can obtain the greatest relic of the Magi world, she will twist his logic to employ his dark magic. As they trek toward the Holy Crown, Koyama skips through a trail of unintended devastation, hand-in-hand with a fellow monster.
