The Lost Son of the Devil's Footprint

Shinra Kusakabe and Sister Iris of the Special Fire Force company 8, recently had a child with Shinra and Iris's powers. He vowed that he will never let anything bad happen to their son, Izuku, as he and Iris decided to raise him to be the person he could be. But, a villain took Izuku as the couple were crushed that their son was taken, for years they looked for him so they could take him back home. Little did they know, All Might was the villain that took Izuku, as he made up the story that he found him on the streets and assumed that Izuku was abandoned. Inko didn't quite know how to deal with it but agreed to raise him until they found Izuku's parents and got a proper explanation on why they abandoned him. All Might didn't want to let him go as he wanted a powerful son to keep as a Symbol of Peace. But it all went downhill when Izuku was diagnosed as quirkless, was forbidden from seeing Izumi, bullied by a lot of people, abused and neglected by All Might, and it never seemed like he could properly smile. The only people that stood by Izuku were his "mom" Inko, his "sister" Izumi, and his friends Katsuko Bakugo and Ochako. One day, Katsuko and Izumi were captured by an Infernal, and the Infernal was far too deadly, and it seemed like it would be the end for them, but Izuku saw them in danger as he felt a change, his muscles started to get burned up as in that moment...

He smiled like a devil, his feet burst with flames as he fought and won against the Infernal. Izuku was shocked as he later on learned of his past and what All Might has done as he goes home to meet up with his true family. With his friends, Izuku becomes the captain of the new Fire Force Company 9, as he gathers Pyrokinetic users to fight against a new threat in the form of a new group made up of Pyrokinetic Radicals and Sentient Infernals.

Izuku is the lost son of the Devil's Footprint, and now! It's time for him to smile like the devil hero he's supposed to be.
