the god eater of highschool dxd

jack was just a ordinary male person before he joined blood and got a fourth gen god arc. he was 12 at the time and he worked under blood for 6 years and has been through hell and back to be who he is but when he was tasked with a mission with nana, gilbert, ceil, and erina (who jack sees as a little sister) to go to Kuoh Academy to make sure the arigami dont attack there jack may be a bad ass but... he has to go to school undercover and that my friends is how you get a badass who also has a sacred gear that belonged to both god and satan so.. yea enjoy
