街でおきた殺人事件。

主人公「川蝉陽太」の恩人でもある少女「孔雀石透子」は殺人容疑で逮捕され、

自身が犯した殺害を供述する。

しかし、透子は証拠不十分で釈放――

周囲はそれを許さず、透子を大きな洋館に幽閉してしまう。

祖母がいなくなり一人暮らしとなった陽太は、透子と共に洋館で暮らすことを決意する。

そして、透子とは仲のいい少女・青葉梟みおん、クラス委員長の燕沢夜、

クラスの変わり者・瑞葉伊鶴も加わり5人での共同生活が始まる。

料理を作ったり、連絡を取り合ったり、他愛もない会話や喧嘩をしたり、

そんな生活を陽太は楽しいと感じていく。

真犯人は誰なのか、なぜ透子は罪を被ろうとしているのか――

鳥籠に囚われた少女を、救うことはできるのか？

Touko was taken into custody on suspicion of committing murder and testified that she was the culprit. However, she was subsequently released due to insufficient evidence. The general public did not approve of this, so she ended up being imprisoned in a large mansion.

Youta was once saved by Touko when he was young, and he decided to live with her in the mansion after his grandmother was hospitalized, leaving him all alone. They were joined by Touko’s friend Mion, the class rep Yoru, and their eccentric classmate Izuru. He felt that it was a pleasant life, cooking together, chatting about random things and having the occasional argument.

But who is the true culprit? And why did Touko confess to the crime? Can the caged girl be saved?
