Tsutaetai Omoi no Soba ni: Aoi Umi Shoutengai

On the deck of a ferry crossing the blue sea, Natsuki stands in the wind with a guitar case in hand and a somewhat melancholy expression. Having once given up on her dream, she returns to her hometown port, where she finds the shuttered storefronts of Aoi Umi Shopping Street and her childhood friend Minami.

As the shopping street is swept up in a wave of urban redevelopment, the two immediately open Canva and create a flyer to recruit members. There they meet Misaki, an unconventional fishing YouTuber. With the three of them together, they form a band.
