Miasmi

Miasmi is the "animal" enemy of Lupus, created from Lupus' shadow as a result of Lupus' neglect towards some Cursed Ones. Lupus' red shadow developed into Miasmi, the spirit of the injustice Cursed Ones. The Miasmi controlled Andrea, at first, and later Sancho in the century of the Bronze Beast. Sancho became an insane killing machine until Miasmi influence and it took Pizne and Kitsuki a long journey to find out how to put Miasmi to hibernation and defeat Sancho... For a while, until they are reborn as KoLy and Pol, who discover that Sancho has risen again, and with more power because the Miasmi has absorbed some of the power of Kitsuki and Pizne.
