Girls' Band, but the Plagiarism System Has Broken Down

(BanG Dream! + MyGO!!!!! + Ave Mujica + Bocchi the Rock! + Girls Band Cry) Fujimoto Yu has one daily task after transmigrating into a world of girls' bands: put pressure on the plagiarist System that refuses to show itself.

In this world, girls' music dominates the scene. There is no Gummy Bear or big dog, no Chinese-style DJ music, no legendary rock bands, and no other popular singers. The cowardly System turns a blind eye to all of this.

No matter. Fujimoto Yu is here. He'll throw Chinese-style DJ music all over the Chinese internet and become the number-one destroyer of its online environment. He'll bring Chihaya Anon together with the others to form a band, write songs for them while watching the band fall apart, face the first spark of human nature, and compete with the hollow-hearted Viola over dog-raising skills. He'll tempt an innocent pink slime into forming a band, then join forces with her to take on naturally competitive Toyokawa Sakiko.

Then, at the global band competition organized by Tsurumaki Kokoro, when faced with the siege of Ave Mujica, Wither or Not, Fairy Bouquet, and the other groups, he'll pull out songs by the top artists of another world, including Guns N' Roses, Linkin Park, and Kenshi Yonezu.

In the band battles, Fujimoto Yu will become the god of girls' bands.

But before all that, he needs to solve one problem: why won't girls' bands accept boys!?
