I wasn't sure if Cool_Otamegane wanted that thread to be for this or not. But it seemed to want to talk about a specific topic
There was two aspects in ch189 that have me confused.
Why keep it a secret that the MC has two personalities in him? No matter how I look at it, I can find no motive at all to keep that a secret. Even if they keep it a secret the specifics behind that (and I am not sure why they would do that either) it's still simple enough just to tell them of the dual personalities. It also helps resolve the distrust and anger they have with him and helps them understand how to handle the situation if it ever happens again. Unless the point is that they don't trust him, so that they are willing to kill him if they can if the other personality comes again? But he's so powerful that getting the MC personality back is their best bet anyway.
With p18, how come the fight atmosphere between those two?
