BEST FRENEMIES FOREVER One morning, fifteen-year-old Yoshida Yuko wakes up to discover she has sprouted demon horns and a tail! Not only that, she learns from her mom that she has supernatural powers and an important mission—to restore her family’s glory by defeating the local magical girl. The magical girl in question is Chiyoda Momo, a student at Yuko’s school. With strength that is only mediocre at best, Yuko’s task to vanquish Momo will prove more challenging than she realizes in this topsy-turvy magical girl comedy.

Shadow Mistress Yuko (a.k.a. fifteen-year-old Shamiko) may have freed her family from the "Feeding a Family of Four on 40,000 Yen-a-Month" curse, but her battle is just beginning! While struggling to defeat her rival, the magical girl Momo, they've actually, kind of, become close friends?! A new magical girl appears in Volume 2 of this supernatural schoolgirl comedy!

WHOSE SIDE AM I ON, ANYWAY?! Ever since awakening to her demon powers, Shadow Mistress Yuko (a.k.a. Shamiko) has been fighting to free her dark clan from the curses placed on them by magical girls. But somehow, she wound up becoming allies with the magical girl who is supposed to be her rival, and now they’re working together to track down a magical girl who disappeared from the town. A new demon invades the neighborhood in Volume 3!

I PUT A SPELL ON YOU Shamiko has finally taken one small step toward becoming an empress of darkness: she’s turned a Magical Girl into her underling (temporarily, of course). Shamiko tries to recruit more subordinates so she can take over Sakuragaoka—but things get exciting when Magical Girl Mikan’s curse gets out of control!

Shamiko has accepted the request of a former Magical Girl to become boss of the neighborhood, and is beginning to manifest more of her demon powers. But between the appearance of another demon and a giant snake god sealed in a nearby mountain, there's a lot more going on in Shamiko's domain than meets the eye.
