sunny boy books

Haruto Watanabe never expected to open his eyes in a world called Suisei—much less one where he’s invisible, untouchable, and guided by a cheeky talking tsubame. Yet the moment he drifts through Onikawa’s towering fortress, watching horned Oni lords prepare for a lavish festival, his ordinary life is left behind. Amidst alabaster halls inlaid with gleaming jewels, the Oni’s ancient rituals collide with a new threat: the emissary of King Goritsu XI arrives demanding fealty, igniting a clash of pride and power.
