@Cutest Dokkaebi You can definitely kill a higher leveled player than you when you have the skills of the world first. But it would be very annoying as it will take a long time. Because you deal low damage and he has high hp. I mean, take sans from undertale as an example, "the easiest enemy". It doesn't matter how much damage it deal if the attack can't land.
I absolutely refuse to read yaoi or yuri and I hate bad translations. At least show some effort and write your translations in english.
