犯され勇者Ⅴ～どんなにレベルを上げても、すぐ射精しちゃうボクのおちんちん…～

Elysia, the Ten Worlds: a universe under rule of monster musumes.

At the lowest of the Ten Worlds you live in fear and oppression, wondering if there was some way to change things.

One day, an angel appears to you with news that you've been
chosen to liberate Elysia from its rulers.

Not knowing quite what to do, you are anointed hero by the strangely wicked angel, and take a sexual rite of passage for divine protection.
