Miyako Misumi

Six months ago, Hikaru vanished for a week. Now, as his best friend Yoshiki senses something amiss and confronts him, the harrowing truth emerges.

In 2045, two children born on the moon and three kids from Earth try to survive after an accident on their space station leaves them stranded.

Ai, a young girl with shut-in tendencies, who tries not to interact with others. She keeps one of her eyes hidden behind her hair. One day, she happens to stop by a deserted arcade, where she meets "Aka." Spinning the gacha at their urging, she acquires a "Wonder Egg," and from that moment, her fate begins to change...

A secret life is the one thing they have in common. At school, Hori is a prim and perfect social butterfly, but the truth is she's a brash homebody. Meanwhile, under a gloomy facade, Miyamura hides a gentle heart, along with piercings and tattoos. In a chance meeting, they both reveal a side they've never shown. Could this blossom into something new?
