Anime Crossover: Eradicating Nightmares in ZZZ Dreams from the Start

[Multiverse Crossover] + [Classic BanG Dream! Bands] + [New BanG Dream! Bands] + [Girls Band Cry] + [K-On!] + [Bocchi the Rock!] + [Fate]…

After transmigrating to Neon, I not only automatically gained fluency in the language of Blue Star, but also unexpectedly obtained the Kamen Rider "ZZZ Driver" in my dreams!

Later, I learned that the first Nightmare was the "Bomb Nightmare," but its dreamer wasn't the same as in the original. Instead, it was a green-haired girl?!
