Canon to the story: Yes
Timeframe: a month after Todoroki moved into the Cacciatore house.
Relevant characters: Jesse, Todoroki, Anima
Shouto was having trouble sleeping. This was to be expected, as it was only his first few weeks living in the Cacciatore's house. The scarred teen decided to go and make himself some tea, but he noticed some lights on. Walking downstairs, he found the married couple with guitars in a room with weird foam pyramids lining the walls.
"Hey," Jesse called to the dual quirk user, making him jump; he thought he was hidden.
"What is this room?" he asked.
"It's a music room. The foam makes it so only the instrument is heard, not the echo. We were going to have a small guitar session. Do you want to listen?" her tone was soft. Shouto decided that it would be fun, and accepted. When he entered the room and closed the door, he felt disoriented for a moment. The smallest noises he was used to drowning out were non-existent, making him hallucinate a sound for a moment. When he took a seat, the werewolves played. Jesse started with a trill up the scale before snapping.
It was fast-paced, with Anima playing the undertone. Jesse was making the harmony, which felt more akin to a Spanish style. Shouto felt the emotion in the piece, and when he closed his eyes, he was seeing dessert with the heat on his skin. He didn't listen to music much, but with the feeling of losing yourself in the tone, he could definitely see why others did. After a few minutes, the duo finished the song, bringing Shouto back into the foam-padded room.
"Could I learn how to play like that?" he asked quietly. Jesse was almost bouncing in her seat.
"Oh, I'd love to teach you! Here." she handed the bewildered teen her instrument before sitting next to him and telling him how to hold and play the basic notes of the musical tool. It was a Saturday night, so they didn't need to worry about school.
"Looks like you get to pass on the teaching Musica gave you," Anima said with a smile. He then went to the kitchen to make some tea for the impromptu music night. He was guessing that this would soon be a common thing.
Needless to say, he was right.
Yes, the one who taught Jesse was actually Musica, as in the Greek demigoddess. Heroes have weird contacts. As for the song, I was listening to an acoustic guitar cover or Gerudo valley by TheOnlyDeerAlive.
