A Journey Through the End of the World with Twelve Yandere Daughters

Shelly, a student at Saint Lian Girls' Academy, is a perfectly ordinary high schooler and an unremarkable member of the Pink FM band... Compared with her classmates, she differs in only three ways.

First, she has no memories of the past three years. Second, for some reason, she has the allure of a succubus, making anyone who spends a long time around her fall madly and hopelessly in love with her. And last, most importantly... she is the mother of twelve daughters. Each of these daughters has their own remarkable qualities and special skills, and most importantly, they all seem very, very eager to... love her.

"Mom taught me the art of cutting and dissection. I want you to see with your own eyes how much I've improved."

One sweltering afternoon, Shelly received a letter from her second daughter, who had suddenly come looking for her. After that, her life changed completely: going on adventures in one apocalyptic world after another, battling terrifying parasites, monsters, biological weapons, and out-of-control war machines, and changing the fate of countless worlds. And...

"Thanks to you, Mom, all the little animals like me. I hope you'll play with them."

"I want Mom to get along with my little friends. After all, it was you who gave me the chance to meet them."

"Thank you for giving me my singing voice, Mom. I have a song I'd like to dedicate to you. I hope you like it."

Shelly: Eek! Everyone, don't do anything rash! Can't we work this out?!
