The Dead Melody of Deku

Midoriya was born with a music-based quirk. He could summon musical instruments. He can make others feel what he feels through songs he plays and can even change other's moods. He can empower others just the same with the right song.

When he was younger, he wanted to be a hero by being a musician. Midoriya knew he wasn't physically capable to be a pro but he still could be a hero in his own way. He wants to save those who seek comfort in music.

Unfortunately, due to a villain attack, Midoriya was killed and became a ghost. He was devastated.

It turns out however, he can still use his quirk and others can hear him only when he's playing or singing. This cheers him up a bit. He still finds himself useful.
He knows he can save lives with his music, so that's what he is going to do. Death isn't going to stop him.

A story I Adopted from OwlyPersona125. I will be slightly changing it and editing the story to fit my writing style.
