A typical Isekai to be honest. A normal high school student saves a classmate, gets hit by a truck, dies, gods say something along the lines of: "Your soul is too pure, reincarnation time.". Gets reincarnated as a female celestial vampire.

Watch as he, now she, goes to find many girls for her harem and happens to save the city, kingdom, and maybe even the world and how the people around her change with her.

A story about adventure, action, and finding one's self and resolving the issues in your heart.

This is, to me, a love-letter to the genre of OP Isekai, which has helped me through some difficult times, I hope it does the same for someone else.
