Hey guys, so I showed this fic to my brother, and after reading he said I should rewrite this series, he said it was good but I destroyed myself doing one piece as a training arc, so that led me to this question.
I will still allow him to enter other worlds, but I feel like I should at least wait until you guys tell me before I make the final decision.
Also I will still keep the Taimanin plot since that never gets shown, that's staying as well.
Apologies for the inconvenience.
