Once Upon a Witch's Death

Traditionally, when a witch turns 15, she's supposed to go out into the world alone to study magic. Makoto's parents, however, believe that their directionally-challenged daughter should get a high school degree. Instead of being sent out on her own, Makoto and her cat Chito find themselves traveling from the bustling city of Yokohama to Aomori Prefecture, where they'll stay with relatives until Makoto finishes school. It's going to be a big adjustment, and it only gets more complicated since "normal" people aren't supposed to know that witches exist… something that she tends to forget.

It all started with the 17 "Origins," whose powers were passed down to individuals who still exist around the world today. A man carrying a coffin and a girl with the eyes of a beast appear in a town. The girl was once cursed by a witch and now searches for her in order to undo the curse. Is the witch who appears before them the quarry they've been searching for? And how can the curse be undone? This quest for revenge against an evil witch begins rolling when the beast captures the witch. This magnificent and intense dark fantasy begins now!

Near the end of the Showa era in the late 1980s, in Misaki town, an old mansion is rumored to be the home of a witch. After moving into the mansion, Aoko Aozaki begins to learn sorcery from a young mage, Alice Kuonji, the rumored witch of the mansion. The Aozaki family oversees the land on which Misaki is built and the heir (Aoko) is tasked with protecting it. Mysterious intruders have been disrupting the bounded field in Misaki, leading Alice and Aoko to investigate. A mannequin or puppet attacks them and is incinerated. As this happens, both of them spot someone running away, a civilian who must not get away having seen magic alive. Unexpectedly, a young boy named Soujuurou Shizuki is drawn to the mansion and comes to reside with them as well.

At the mysterious orphanage where Sheena lives, death is nothing new to its residents—girls who no longer have families of their own, who are raised as weapons of war, taught to kill and take the lives of others without batting an eye. Everyone, that is, except Sheena, who wishes for nothing more than the growing conflict around her to end. On the night of her roommate's death, Sheena meets a strange girl covered in blood, who smiles despite the turmoil surrounding them. The next day, the girl appears as a new student in Sheena's class and introduces herself as Mimi. Initially thought to be a school myth, there are now whispers in the orphanage's halls that Mimi is their secret weapon—an immortal who cannot die. When Mimi is later assigned as Sheena's new roommate, Sheena's world grows even more complicated when she begins living with someone who loves and welcomes death, when all Sheena wants to do is stop it…
