Now wait just a minute!
Ugh characters acting like Aikido actually works in any way is like watching a movie about mathematicians and they regularly and consistently gets 1+1 wrong...
Why do they believe he learned aikido through correspondence (distance) courses, that is stupid, he should have said he learned it through a MOOC (Massive Open Online Course).
If he has illusion magic and memory magic, why bother hiding his powers in the first place? Literally anything he does can be covered up. So then why do nothing when a criminal comes in and forces girls to undress?
There’s a difference between mild stupid and isekai stupid. This is the latter.
