Fandom: My Hero Academia

On special occasions, Shoto pulls out Endeavor's credit card to treat himself and his friends.

He can also perfectly replicate Endeavor's signature and knows how to erase his credit card history to cover the evidence of splurging Endeavor's funds.

The only one who's figured out how he learned to forge and hack so well is Izuku, who pledged to carry the secret with him to the grave.
