Chapitre 55: Towers and Gates, World Building, Humanoid S-Rank Monsters

It had only been a few days since the Heroes transferred over into this world, so the changes were still minimal. But what would happen after weeks, months, or even years of living in this world? Would Tatsuya get tired of being rejected and begin taking women by force? Would Ryota become so disillusioned from reality that he would aim to become something akin to an Evil Overlord?

What about Akira? The obsession he has had with the Student Council President since Elementary School has only grown more uninhibited since arriving in this world. 

And it wasn't only the S-Rank Heroes that were experiencing changes, as every single one of the Heroes was changing one way or another, whether that change be a small or large one.
