A sweet and gentle story of youth, all starting with a lost item.

Rei Mitsushima, who had been active as Pretty Soldier Churi Reiu, suddenly announces her retirement on her 22nd birthday. She ends up working behind the scenes at the Pretty Soldier Special Operations Agency, but her pride gets in the way, leading to one failure after another... A second-career support comedy for all those who "used to be"!

One day, a transfer student joins her class. But while all of the other students gush over how gorgeous this new girl is, Tsubame is taken aback. Can’t you see, she has a bird’s head?! she thinks. It turns out that Tsubame is the only one who can see this girl’s real form. Everyone else only see the magical illusion that she cast on herself. Everyone else just sees Suu as a normal, but gorgeous girl. Tsubame wants nothing to do with her, but Suu latches onto her, as the only person that she can share her secret with, and from there, the adventures begin! (Source: Living tall in Japan)
