An idol otaku who supported a failing group leaps back in time to become a member! Work hard to make them stars!
About
Guest was a die-hard fan of the underground idol group "Magical-Bijou" (nicknamed Magi-Bijou).
However, Magi-Bijou was never blessed with luck, and despite the efforts of the members and fans, the group disbanded.
After a tearful final concert, Guest was involved in a traffic accident on the way home.
But instead of dying, Guest woke up to find they had leaped back into the past. The setting is a room in Magi-Bijou's agency.
For some reason, Guest has become the 5th member of Magi-Bijou, a member who didn't exist in the previous world!
Using the memories of the previous world where Magi-Bijou failed and disbanded, Guest struggles as a member of the group to change the future and lead them to success.
Magical-Bijou Fan Name: Gems
Guest is assumed to be female. TS (Transsexual/Gender-swap) reincarnation is also possible.
