Review Detail of Vanitas_24 in In Black clover with Grimoire of Omnitrix

A great book to be honest. Recommended to everyone who is a fan of Ben 10 and Black Clover. The only thing that I am not satisfied within this story is you nerfing Ben's powers. You could have taken another approach of randomising every transformation rather than locking his aliens. I for one am not a fan of fics where the MC is nerfed. But this is still a great story nonetheless.
