In the 17th year of the San calendar, when Bohr Kelermo was compiling the illustration handbooks for the animals and monsters, he found the secret as to how the monsters released their extraordinary powers. From then on, he started to study about transplanting the blood of the monsters.

The death rate was more than 50 percent, and even when there were no deaths, the organs that had been formed by deified cells countercharged, turning one into a terrifying creature.
