The Twin Angels—Haruka, Aoi, and Kurumi—defeated the demon king Zelusifer and protected world peace.

They lost their powers as Twin Angels to save the injured Lilica and Eris, but they discovered new challenges and hope, and returned to their calm and peaceful daily lives. However, one day, they received a message from Tenshi-chan, a fairy who had completed her role, stopped functioning, and was supposed to have disappeared.

"Help me, Haruka... Aoi..."

One day, a mysterious transfer student suddenly appears at the school. Later, in Italy, Eris and Lilica go missing while recovering. And what's more...?!
