Rock in Soul

One day, Haru, a high school girl with a strong desire for approval, finds an old guitar in the music room's storage room. She carelessly touches it thinking it's okay to just scratch it a little, but ends up dropping it and scratching it...? Haru quietly returns the guitar and pretends nothing happened, but when she gets home, the guitar is in her room for some reason! A girls' band comedy about Haru, a modern high school girl who dreams of becoming a buzzkill, and Aki, a high school girl from the 90s who was obsessed with guitars! (Source: Kadokawa, translated)
