The Vividteam has defeated the Alone, but a new threat arises. With the Autobot's help, can they save the day again?

Origin story for A-Rise, set before Love Live: Gunpla Battle Project.

Otonokizaka is going to close down! Honoka and her friends form a Gunpla fighter team so that they can join the tournament, boosting the school's popularity to prevent it from closing. (Sort of like S1 of the show, but with Gunpla battle instead)
