She has finally turned 15 and it’s now time for the demon to claim her body... but then an accident happens...

One night, senior high-school second-year Nishina Airi is abducted. When she wakes, she is trapped in an uncanny, isolated space with other students from her high school and forced to take part in the “Werewolf Game”. Thus, a death game filled with fear and terror that would pit “Werewolves” and “Villagers” against each other, force them to murder – a game with rules so absolute, defiance is punished by gruesome death – begins.

The dedicated student council secretary is being hit on by a half-Japanese underclassman.

Iyogi is too kind for his own good to refuse helping others. Even today, he ended up looking after a new transfer student tasked by the student council president, Akira. Enzou, the said transfer student, was raised in France: foreign-like features and gestures, stylish appearance—he’s really attractive.

For the xenophobic Iyogi, however, it was the worst thing that could happen.

Not to mention that love helplessly blossomed for Enzou...?!

He just went to school and carried on with his life. Akatsuki has always had better vision and body movements than the average human, but the most he got out of it was never losing a fist fight. His adopted brother, Seibu Tsubasa, who he met five years ago when they were both 9 years old and who has been like a real brother to him, on the other hand, is a genius who got his doctorate at the age of 9, and teaches Akatsuki’s class at the middle school. But Akatsuki’s life changes when he learns about his Kigan or machine eyes, an ability only a handful of people in the world posses that allows the body to not have any limits. For example, one would be able to see at almost 360 degrees and process all the visual information available, while making decisions faster than an average human can even begin to imagine. Now as a pilot for the Warbird jets that he saw in the sky everyday, he has become the military’s secret weapon against the impending restart of the world war. [vyc]
