Ban did his best to hide the nervousness he was feeling. Although it was not confirmed, there is a high chance that him being unable to awaken was one of the reasons for the sudden Beast Tide.
He put the matter at the back of his head for now. Just like what Joana said, if being a 'freak' was really the reason, he can't do anything about it anymore and it's not that he wanted it anyway.
However, he did make a promise to himself that he should at least help defend the city with all his might when the time comes. Although his current strength was still negligible compared to those at the Multi Realm, he thought that he could do just fine fighting opponents at the Singular Realm.
