Demon Diary 6 features story by Jee-Hyung Lee and art by Kara Lim.

Years ago, an insane demon horde attacked and destroyed a human village, killing all of its inhabitants... except one. A human boy, Chris, called out to the god Rased during the attack and, as a result, was spared. As an act of mercy, Rased buried Chris's memories of the devastation but, though the memories were gone, Chris's feelings of hatred toward demons remained... and grew stronger with time. With all of this in mind, you'd think it wouldn't be too hard to get Chris to attack a Demon Lord... and you'd be right!

The one exception to that rule is Demon Lord Raenef V, the cuddliest, most lovable and, subsequently, most laughable Demon Lord in existence. Though Chris and Raenef first met as adversaries, they actually managed to develop a close friendship... until now. Raenef has recently developed a frightening and terrible personality typical of a Demon Lord and, in the process, has managed to turn his friends, his tutor, and even his dead predecessor against him.
