if so, why Peter have Hulk's poster in the bedroom?

there were guys like Silver Shroud and his bunch of friends. While in the Fallout 4 they are showed as comic heroes, but lore indicates that there were crime fighters and criminals like those. There also are some supernatural things happening in the world, which can be seen even in fallout 4, as well as weird stuff like that family that survived for hundreds of years by using the blood of their crazy head of the family with a crown. Not sure if they were Cabbots or something like that

and it keeps getting worse with each chapter

they have to be at least that stupid to make MC look smart

This is just a common version of a harem type story, where every girl author wants is falling in love with MC at first sight and doesn't mind sharing and all girls get insulted if MC is called Beastman or Demon or whatever else and get protective ( that would be fine for empty headed girls from 21st century, but his other girlfriend is Aela, who is nothing like normal girls of our time, even in the game) The only interesting part is his restaurant being connected to different worlds, but even is ruined, because every character is dumbed down.

I still can't understand. Is there Kisame or Zabuza participating in the Chunin exams? Or both?

that's not low level Haki. that was how Observation Haki worked in the anime before characters learned how to use it

in canon that school was only-girl school before, which is the main reason why the amount of boys in school is low, which also could be a reason why Sona have a peerage full of girls.

sorry, I don't understand that. I learned English to some extent, but that's it

but, yeah, every reincarnated knowing those for no reason is weird
