8th Loop for the Win! With Seven Lives' Worth of XP and the Third Princess's Appraisal Skill, My Behemoth and I Are Unstoppable!

Overview

This is a story about Remille, an adventurer who died. Specifically, he's died a lot—seven times now, always at the hands of vicious monsters. Every time, though, he's returned to the same day, three years prior. He's tried everything at this point, from sword fighting to magical arts to beast taming, but it always ends the same way. Is there any hope for him in this 8th loop of his life? Perhaps a chance encounter with Princess Ciel might change things? Her magical eye can see all possible futures—and with Remille's vast stores of XP from seven lives of adventuring, just about anything is possible! Add in the fact that his erstwhile feline friend Catra isn't exactly what she seems (and how the princess herself wants to party up with him) and this 8th loop might just be the charm!
