Foreword

The indescribable battle to be the most powerful ended with Rimuru as the victor, but the state in which the combat ended was the closest thing to death.

Forced to take a break while he recovers his abilities, he ends up on a planet Earth where "heroes" exist and there is a bald man with an incredibly strong cape.
