I get that but both of them knew how strong these guys r especially Haruto and were like “We r going to have our revenge!” so they should’ve known that they needed to level up quickly. If they had done it, they wouldn’t have been struggling this much. But I guess if they did that, there would have been even less chapters. ╮( ̄▽ ̄)╭
Did any of that make sense cuz I don’t think my brain is braining right now (〜 ̄△ ̄)〜

I don’t get it. They level up when they kill each other right? So why didn’t they kill each other when they were in the poison dungeon and just keep doing it when they have time? Like I get it would hurt and all but they experienced worse ways of dying. (⊙…⊙ )?
