Can't remember the title of the manga/anime, it was recently made into an anime. I'm looking for a shounen MC with long white hair. At first he appeared with a mask and apparently the world's power system is based on how many people you've killed (there's like a kill count number next to a star symbol) the higher the number, the stronger he is. He's apparently a general (?) who lead a team of the strongest soldiers but shit happens and there's a time skip + dimension change (?)
He was in a class of soldiers called A1? A? But the class got left behind in the dimension that was collapsing? Or when to shit? And he's in love with his best friend's daughter, not on purpose. His best friend (short black hair) was tortured/brainwashed so he became "evil". The main villain is a blonde guy who's the former boss of MC in the military?
Anyway, ive tried searching on google but nothing came up and i think the manga/anime name is in english? Please help if anyone knows the name, this has been bugging me for weeks ╥﹏╥
