He might, for now he is super op that he could be a knight or a high cleric. But he thinks it's bothersome and just wants to read books, so he downplays his abilities... So he says.
He wants to be a librarian but has magical talent, so he hides it. Like the MC pretending to be mute. On the earlier translations, it seems his family are trained soldiers at the frontier so I guess he also had some training with the sword. Yup, pretty OP guy.
So uhmm can someone clear my confusion. Does he —librarian guy— have a secret identity or something?
