is a shōnenmanga by Masanori Yoshida. The manga ran in Shōnen Sunday from 2007's issue 2/3 to 2008 issue 40.

On the surface Yu and Minami are very typical; they work at a coffeehouse and live mundane lives. What most people do not know is that Yu and Ninami are both assassins with supernatural powers. As they carry out their contracted kills, they search for the people responsible for the alteration of their bodies.
An assistant to Genzaburo Kujo for the first half of the series and an independent assassin for the second half, Yu relies on the heat generated by his body and a natural talent in the martial arts to kill. Yu's body was heavily augmented after being rescued as the sole survivor of a plane crash and used as an experimental subject. His body can to heat up to nearly 1000 degrees (and higher with training and the right equipments). Because of this he relies on Ninami to keep his body cool, in hopes that he can live long enough to have his body returned to normal and exact revenge on the head of the experimental project. Due to his unusual body, he has to sleep inside a refrigeration device and wear special clothing that controls the amount of heat released.
