フーマンジー (Fumanji)

"Yurina, a top producer who turned the K-POP idol group 'Dragon Nest' into global stars, loses everything due to a rival agency's scheme. On the brink of despair, she is suddenly transported to another world. There, she meets a nameless young slayer named Kou. Using her exceptional producing skills, Yurina unites a diverse group of races to build the ultimate Dragon Slayer Guild. Along the way, she uncovers a massive conspiracy and, together with her new companions, throws herself into a battle to save the world." (Source: Translated from LINE)
