The Testament of Sister New Devil: Storm! #1

In a quiet moment between sisters, Maria persuades Mio that sharing a bath with Basara will deepen their bond—but the ritual awakens the ancient Servant-Master Curse, binding them in a connection neither expected. As the line between loyalty and desire blurs, the three find themselves caught in a delicate, charged dynamic neither can easily escape.

When Yuki decides to move in with Mio and Basara to keep watch, what starts as a straightforward mission quickly spirals into something far more complicated—especially with Maria’s playful magic adding sparks to an already charged atmosphere. Basara finds himself caught between duty and desire, all while navigating the shifting dynamics of a household that’s anything but ordinary.

In "Summer Camp (Part 1)," Basara Tojou finds himself caught between the growing tension of training and the unexpected allure of school nurse Chisato Hasegawa, all while Mio and Maria Naruse push their limits in preparation for the looming battle against Lord Zolgia. Amid the summer heat and campfire stories, old bonds are tested and new feelings simmer just beneath the surface.
