Refund! This Diva Isn't What I Was Promised!

Yun Che is reborn in 2007, the year song idols descend upon the world. Armed with a global library of god-tier songs, he plans to contract Hatsune Miku, dominate the music wars, and make his mark as the King of Idols!

But when the light fades, there’s a tiny blonde girl in his arms, holding a lollipop and calling herself “Yu.” Her rating is only E!

“Return her! System bug! Where’s my SSR?!” Yun Che cries, clutching his head.

The haughty song idol smacks him with her lollipop. “How rude! I am Rosalind! Keep whining and I’ll send you off to the afterlife with ‘Gokuraku Jodo’!”

And so, the most outrageous music-war duo in history is born. While other song idols perform hymns or death metal on the battlefield, Yun Che’s mind races through a repertoire of songs: “Senbonzakura”! “Renai Circulation”! “Ievan Polkka”!

“Miss Tangyin! You’re off-key! That sound blade is hitting our own people!”

Forced to play along, Yun Che can only take his unreliable song idol and use Earth’s god-tier tracks to give another world a little taste of anime culture. But when “The Unknown Mother Goose” fills the skies, “Kami no Manimani” heals wounds, and even “aLIEz” is…

The enemy: “Wait… you call that an E-rank song idol?!”

Yun Che: “…If I say I drew the wrong card again, will you believe me?”

This is a hilarious tale of one guy taking a whole internet’s worth of magical songs to blast his way through another world on a ridiculous, passionate adventure!
