You do realize Hito Hito no mi just means human fruit right? It could mean any fruit in one pice that transforms you. From Luffy to Choppa.

Story good there just a couple problems i seen. The big ones are the names and the small one it say he eat a trask hito hito fruit. I dont think there will ever be a trash one and je didnt eat one he eat a different fruit. You do know hito hito no mi mean human human. The real name of the DF he ate is Nagi Nagi No Mi

Just get the names right ffs. everything else seems good. I do hope you continue updating the novel tho, its pretty interesting.
