Isekai wa Mazoku Idol de Afureteru!

The protagonist is shocked by the announcement of her favorite idol's disbandment and dies in an accident. She misses her long-awaited Budokan concert, and as her consciousness fades, a strange sight unfolds before her.

She wakes up to find herself in an alternate world where demons and humans coexist. She's reincarnated as Yuria, the daughter of a theater owner drowning in debt! If things continue as they are, the theater will go bankrupt and she herself will be sold into slavery...?!

Just then, a beastman named Cain, who looks just like her idol from her previous life, appears and asks her to help out with any chores she can to protect the theater. After meeting him, Yuria decides to produce a demon idol and change her future as a slave!

She aims to repay her debt with the help of her non-human companions—vampires, elves, slimes, and beastmen—but a powerful rival group also appears. Will Yuria be able to repay her debt safely?!

A demon x idol x alternate world fantasy begins!
