The Research of a Workaholic Fiend's Soul!?
In the Underworld known as "Darkworld", "Kozaky" was famous for being the top authority of linguistics. But because he overworked himself, he went insane, and has since immersed himself in studies far different from linguistics. However, the Darkworld Academy of Science refuses to acknowledge his research...

Though he's not very strong, he fights with his head!
This is a photo of "Kozaky", from around the time he snapped. Since he was expelled from the Linguistics Society due to going bonkers, he has been attacked by other monsters, but manages to survive using his smarts.

??##Together with his research colleague, the two continue to make cutting-edge breakthroughs??##
"Kozaky" showed his natural talent in the Darkworld Linguistic Society. He joined up with "Magical Scientist", who had a brain equal to his own, and together the two are continuing to develop new things!

He researched for several years, day and night, without rest!
He left saying, "I've already lost my mind," and dedicated himself to constantly researching, day in, day out, without rest. While trying to come up with his own original theory, he currently studies on how to make monsters stronger.

The fruits of his research: His own personal robot!
He built the robot "Giant Kozaky" through all of his hard research. However, its incredible strength baffles the human mind, and has lead to it being compared to, and even confused with an Archfiend! Its serial ID number is 539.

A request for physical enhancement
Looking at the successful development of "Inpachi", "Gagagigo" requested physical enhancement, explaining that he wanted more power so he could better serve his master. "Kozaky", seeing no reason to refuse when he could get more data out of it, began a dangerous series of experiments to enhance "Gagagigo"...

His experimental body goes on a rampage!!
It seemed like the experiment was successful. "Gagagigo" was definitely enhanced. However, he lost his true sense of self as a result, and went on a rampage. In fact, "Magical Scientist" predicted the experiment would have a 0% chance of success, but "Kozaky" refused to listen.

'''His laboratory exploded. His current whereabouts are unknown...'''
