- Izuku still winds up at the training camp but as a field medic.
- Izuku still gets injured a lot, though nowhere near as much as in canon.
- Shoto still thinks that Izuku is the secret love child of someone he has a close relationship with. This time it's Detective Tsukauchi.
- Jerkass: The story has a pantry of unpleasant characters. The cakes go to Officer Mori for doing paperwork while Izuku is running screaming from a kidnapper while carrying the victim.

- Paying for the Action Scene: Izuku overpays some kids for the pitcher of lemonade he grabbed from them to neutralize a Villain's Quirk.
- Point of Divergence:
- Izuku manages to predict when three Villains are going to make an appearance after a long time quiet, which leads to them being caught. And since they're caught, that means All Might doesn't use up his limited time in his Hero Form. Which means he's on-site at the USJ when the League attacks, which results in much fewer injuries than in canon.

- Izuku keeps getting stabbed in the leg.

- What the Hell, Hero?: All over the place.
