A band simulator, but all girl-heavy!

She traveled through time and became a young lady from Tokyo. Her worldview seemed to be lonely rock and roll. The golden finger was a band simulator. She thought she could feed back into reality through simulation and become a genius band girl in one fell swoop. However, the first simulation copy was "Save the band CRYCHIC".
After going through untold hardships, they finally succeeded in simulating bands such as CRYCHIC, mygo, and gbc. When they were ready to have fun with the band in reality, they found that their former bandmates came to them one by one.
Takamatsu Deng: Didn’t you say you wanted to be in a band for life?
Nagasaki Suyo: Please! If it weren't for Xiao Kui... I...!
Toyokawa Shoko: It was me who invited you to form a band first...
An He Subaru: It turns out that I am not the only one...
Saotome Aoi finally realized that what kind of band simulator is this? The word "heavy girl" was clearly written all over it!
