Wonder Egg Priority

A pair of mysterious voices lead 14-year-old Ai Ohto to a strange egg, promising her a chance at what she wants most.

Ai meets Neiru, a girl buying Eggs; despite Ai's frosty reception, that could change after the next time they crack their Eggs.

While buying Eggs for herself and Neiru, Ai meets Rika, a former idol who is there for the same reason; Rika quickly pushes her way into Ai's life.

With Rika out of action, Ai is on the run and struggling to protect two girls from the most devious killer she's faced yet; meanwhile, a fourth child is also fighting to protect the girls in the Eggs.

Ai, Neiru, Rika, and Momoe are quickly becoming close friends as they continue to protect Eggs; however, as they grow closer, questions pile up and tensions rise.

The girls are attacked by a dangerous new type of enemy while trying to protect their Wonder Eggs; Acca and Ura-Acca may have a solution, but Ai is more concerned with the budding relationship between her mother and Mr. Sasaki.
