Brocken Blood

In the 17th century, German alchemist Johann Schultz created a witch and infused its power into his blood. Centuries later, Shurutsu Kenichi, a high school student and third-generation German, secretly acts as a Brocken heir to combat those misusing the artificial witch theorem. His cousin, Yomoda Rena, devised a scheme that led to this conflict. Despite his efforts, Kenichi inexplicably transforms into a Magical Girl "Heroine." The story includes the one-shots "Nurse Assault!" and "!Bloomed in Action!"
