Wonder Egg Priority

After the suicide of her only friend, Koito, Ai Ohto withdraws from the world, unable to understand what happened. A mysterious figure eventually leads her to purchase a Wonder Egg, and when she breaks it inside a strange dreamscape, a girl appears who desperately needs protection. In this place, the fears and traumas haunting vulnerable girls take monstrous form, and Ai must fight them if she wants her charge to survive.

Ai is told that saving enough girls may give her a chance to bring Koito back, so she keeps returning despite the danger. Along the way, she meets others carrying losses of their own, and their shared battles grow into friendships that expose wounds far deeper than they first appear. Every egg brings Ai closer to an answer, but also forces her to confront the questions she has been avoiding about Koito, grief, and herself.
