The Demon Lord Is Pathetically Weak, but His Heroine Wives Are Overpowered!

In my previous life, I was a Demon King who made the Three Realms tremble. I died at the hands of five heroes who joined forces to defeat me.

In this life, I was reborn as a sickly, good-for-nothing high school student. I thought I could live a peaceful life...

Until, on the first day of school, five beautiful girls cornered me in the school restroom.
