Bocchi the Rock! Re:

Hitori “Bocchi” Gotoh is an introverted girl. During her middle school years, she started playing the guitar, wanting to join a band. But because she had no friends, she ended up practicing guitar for six hours every day all by herself. After becoming a skilled guitar player, she uploaded videos of herself playing the guitar under the name “Guitar Hero” and fantasised about performing at her school`s cultural festival concert. But not only could she not find any bandmates, before she knew it, she was in high school and still wasn`t able to make a single friend! One day, Nijika Ijichi, the drummer in Kessoku Band, reached out to her. And because of that, her everyday life started to change little by little.
