The Day I Became a God: Season 1

Yota Narukami had a life to live—or at least he did until he meets young Hina, who declares the world will end in 30 days. Scorning her prophecy, he refutes her prediction but questions himself after seeing her abilities in action.

Moving in, they find a common bond most unexpected. Is it true, is it really the end? More importantly, why did she pick him to spend their final moments together?
