If Only I'd Known the Girls' Band Was Going to Play in a Band

A meticulously crafted author, using traditional methods! The author is the guitar that Mutsumi was holding during the Black Blade Night arc, so there's no random mix of cat, chicken, dog bands, GBC, and solitary rock? A bad woman? A good girl! She's transmigrated to Tokyo in another world, still in the girl band Kirakira + Dokidoki! She seems to still be the young lady of Tsukimori! However, her situation is slightly better than Xiangzi's; it seems her father was tragically killed in a car accident and returned to the Golden Throne, leaving her only with an inexhaustible amount of money. The original owner was still a member of C-group, and the time is still after the Black Blade Night arc. Most importantly, the original owner died in despair after modifying her own sword! To survive, she must revive CRYCHIC. Looking at the remaining people in the practice room, Yuzuki Tsukina's eyes revealed a resolute look: "I'm here today to revive CRYCHIC!"
