Hello,
quite some time ago i read a manga about a boy who had to go to a special school
his mother or father or even his grandma attended.
Its a weird school where ppl are put into a faction and receive a body mark they wont know how large the body mark will be before they receive it depending on how large it is the more power you have.
Like always the main char will get a small dot below his eye and will be marked as the weakest but further in the story he will have enuf power to stop time.

The female main char is a girl who also has a small mark but has very strong katana/sword wielding skills in the first few chapters she will face off against a (woman) who has the looks of a fat dude VERY FAT this is her special skill the katana wielding girl will hit the enemy in a weird manner burning all the fat off and that is the end of the fight (this is also how u will get to know its a girl and not a FAT boy)

I dont know if i wrote enuf about the story so u know what i am talking about but it would be very helpfull if u could tell me wich manga this is thanks in advance.

Also at the end (massive spoiler) u will get to know that the school was semi made to harbor a Nuke that is frozen in time and the school keeps it that way near the end it will explode in its original time wich is world war 2.

That's Yakuza Girl I believe. Read that ages ago.
