I Am Your Protector

Izuku, a hero-in-training, is battling hard against his childhood friend (now rival) Katsuki, to prove that he will best him and become the number one hero. With determination in his heart, Deku will do anything to become stronger.

Moved by his aspirations, Tenya Iida, Deku's best friend, agrees to help him perfect his shoot style and increase his strength and mobility to allow him to use more of his power. But after Iida sacrificed his arm for Midoriya's safety, his feelings for his friend start to take a different turn. Perhaps he was more than a friend all along...
