Solider Izuku x Villain Momo

In this AU Izuku is born with a quirk called 'Gunslinger' which means he has perfect aim in any weapon that fires a projectile and has unlimited ammo but all he has to do is think of it and can add special effects. All might isn't 1# hero but 2# due to him only being able to be buff for 1.3 hours. Shoto is dating ochako who is cheating on Izuku. Momo is a villain due to her parents being murdered by a fake hero so she only kills fake heros and villains.
