Other names: 讨厌蓝天谎言的蝉子, 青空嫌いの嘘つきセミ子, The Lying Cicada Who Hated the Blue Sky
This is a manga based on the fourth chapter of Karate's novel, The Story of a Macaron-Loving Girl who Lived a Thousand Years Somehow. It all started when a little girl claiming to be from the Cicada Kingdom appeared on his doorstep... This story is a little bit warm, and a little bit painful. But most of all, it is a wonderful story.
