I dont like that his arrogance shoots way too high the moment he got back in time.. and i dont like it much more that he's so confident already when he only got his skills "technically" from stealing it from someone.. and he doesnt try to get used to it first or assimilate.. he just runs directly into a C rank gate that was actually an A rank gate.. and boom! More skills! Perfect ( ̄∇ ̄") he barely had E rank skills before that.. his arrogant and confident characteristic doesnt have a strong foundation to support him in a way that makes sense┗( T﹏T )┛some may percieve this as too fast paced but no.. its just that his character is already so confident of his newly found skills that he's already rushing to defeat double his supposed capability. In other stories, this is the extra that dies quite easily because they're reckless and thinks that they're too strong.
