BanG Dream!: Star Beat

Toyama Kasumi is a shy first-year high school student who has lost the ability to sing and express her emotions after being mocked for performing her favorite song. Struggling with loneliness and unable to make friends in her new school, she finds solace only in an exchange diary kept on her desk, where she communicates with a mysterious individual named Saaya. Saaya appears to attend classes at fixed times, serving as Kasumi's sole emotional outlet during her melancholic days. Everything changes when Kasumi notices a trail of star-shaped stickers leading her through the streets. Following them, she arrives at a pawnshop and discovers a unique star-shaped guitar called the Random Star. Captivated by the instrument, Kasumi feels a sudden desire to transform herself and chase her dreams. However, she soon meets Ichigaya Arisa, a girl at the pawnshop who offers her an unexpected proposition. Instead of purchasing the guitar, Kasumi can have it if she agrees to join Arisa's game known as BanG_Dream!, setting her on a path toward self-discovery and music.
