Ototama ~Boku-tachi Girls Band Desu~

"We're gonna found a band for sure, I promise!"

With this promise, the protagonist had parted with a boy from his childhood. But already 10 years later, it was time to move again. Summer passes and by late September, the protagonist had already returned back to his hometown again, due to his father's job situation.
He wonders if that friend from back then still remembers their promise...

Being torn on whether to be hopeful or to give up, the protagonist introduces himself to the class as the new transfer student, is met with baffled eyes and gets hugged by a girl unfamiliar to him.

Could it be? That's the boy from his childhood! The protagonist is also baffled by how much his appearance and looks had changed. Does he still remember the promise they had made when they were children?

The protagonist looks at him sincerely and asks him for his support if he still wants to continue making music.

And from this day on, he and three other boys begin forming a band, whose goal it is to perform a gig on the school cultural festival's stage.

While as pursue that goal, their bonds deepen and these boys don't realize they've already awoken to a new pastime of their's.
