Soshite Kono Sora ni Kirameku Kimi no Uta XXX

Rumina’s (Lumina) father has died of some disease and the 2 twins, Edios and Michael have died in battle. One day she goes on some scavenger adventure with Pelmo and opens a Pandora’s box. From there comes out a ghost who takes over Pelmo’s body and tells her that he can revive any people who did not die of natural causes. She doesn’t listen to the full rules of his contract and agrees to revive both Michael and Edios. Unfortunately this causes everyone to forget that she’s the Queen or who she is. Instead Michael becomes King and Rumina finds herself running around the castle hoping for someone to recognize her face.
