Main characters that look sweet and nice but actually have a dark side!

World turned into a game kind of like a killing game where you have to survive but not only survive from humans but from monsters and the 1 that was left standing to the very end was not the strongest not the smartest and not the richest but the main character and he was given 1⁄2 chance and this time he is going to make things difference

Basically, he is just about to die but then he woke up to the day that the doomsday started and he said if I'm going to start all over again I'm going to be the strongest and basically even if he dies again he just goes to the same day again like that's it's ability but his ability does have limits so he just doesn't randomly kill himself

Basically his brother was betrayed by his teammates and he swears to take revenge on them by the way they didn't know he had a brother because he want to another world and the way his brother found this out was because the brother left all his memories in like this object if he found the object

I think we all know about this 1

I don't really know how to explain this 1 but 10 out of 10 you just have to read yourself to know how good this is

Warning this has suicide in it was not sad it's just his ability cause if he dies by someone else or himself he goes back 1 day and he wanted to go back to a certain day before someone became really strong and kill them so he had to kill himself a lot of times
