Slightly inspired by the My Hero Academia fanfiction, "Comforting Touch" by NyghtWalker on fanfiction.net, when it comes to Midoriya's powers, although with noticeable differences from that story.

Izuku Midoriya. Quirk: "Emotional Support." By making physical contact with others or himself, and providing words of encouragement, he can boost the morale of others and increase their power or extension of their quirk or physical ability. It takes a toll on his mental state though.

Midoriya is the youngest in age, and is quite smart, but his quirk isn't all that much. Can he become the hero he wishes to be? Can his childhood friend, Yui Kodai, help him in any way, despite her lack of emotional expression?
