DUR-HUR-HUR!
DEY GOTS IT RONG WHEN IT WAS IMPORENT
SO FUNNY HUR HUR HUR
Actually, it's not even remotely funny; it's just fucking stupid.
Stop it.
It has never been funny, in any manga I have ever read; it has never been useful to the story, never been even remotely humorous, and never done anything other than create pages of useless shit that never ends up mattering after the MC uses his god-like powers.
Even worse, I'm sure the MC will act grateful, or happy, that everybody around him will be emotionally damaged by this stupid trope... right after he complained about having emotional damage, when talking to the princess.
Entirely Fucking Useless.
