@zetsuravez - Suimei wants to keep a low profile, go unnoticed, so he altered their memories to downplay his skills. He fought them legit just to get an idea of what to expect in combat in this world.
@CelticMutt thanks for telling me... i have an idea he's doing that but not sure if it was memory alteration or something... but why did he alter the memory of the other girl?... she saw how suimei fight, right?...
I'm also not liking the MC a little. I feel like he acts too smug. Sometimes has reason to be, other times unnecessary. Then he can suddenly change to sound so polite, like he's pretending. Maybe I'm in minority. But oh well, it's isekai, must read 😂
