Mafuyu and Tomo’s life at St. Mihailov Academy has been a nightmare since their father disappeared, but when they come across a wounded stranger on the grounds, all hell breaks loose. Alexander “Sasha” Nikolaevich Hell, that is, who becomes both their classmate and protector even as he continues fighting in a secret war over mysterious artifacts. Meanwhile Mafuyu discovers that nursing Sasha to full strength requires more commitment than expected, as he’s a Qwaser, an elite warrior who can wield the power of an element as an array of weapons. The catch? To do so he has to draw upon a special substance that only a woman like Mafuyu can produce!
