Sakai Ken'ichirou

Ken'ichirou Sakai is one of the main antagonists of Harmonize. Alongside his lover, Sayuri Kakihara, he leads the Kamijo Corporation, and fights for the realization of the will of the collective unconsciousness of mankind -- even if that will leads down paths of destruction or nothingness.

He is Sayuri's Dragon.

Personality
Very much the public face of KIRIJO SPLINTER GROUP, Ken'ichirou is outgoing, very social and witty, and generally the life of most parties he goes to. For this reason, most people not in the know believe him to be the brains behind the Splinter Group; in fact, this could not be further from the truth.

He is extremely loyal to Sayuri, and spends most of his time supporting her. He is her primary sounding board for ideas, her lover, her best friend, and business partner all wrapped into one. He can and will do virtually anything for her -- including turn the world into orange juice. He defers to her on most things, particularly those having to do with business and the Grand Plan.

Privately, he has some misgivings about Sayuri's theories about the collective unconscious and free will, but can never quite logically argue against them, so he avoids bringing this up.

He is also easily excitable; and very hot-blooded when given reason to be.

History
A proud graduate of Tokyo University, Sakai specialized in biochemistry. A successful student his entire life, he was immediately snapped up by the Kirijo Group following graduation. After a year in the company, he was transferred to the highly-secretive division doing Shadow research, where he met Sayuri Kakihara, one of the up and coming scientists working on the project. The two became fast friends, bonding over their similar experiences at Tokyo University and mutual fascination with the Kirijo Group's research.

After the Kirijo Group turned over its Persona research to the Japanese government, Sakai was reassigned within the company. His new assignment didn't last long; once he found out that his longtime friend Sayuri was leaving the company in protest along with many other Kirijo employees, he decided to follow her.

Somewhere in this time period, Sayuri confessed her love to her long time friend. A happily stunned Ken'ichirou gratefully confessed the same. From this day, the two were even more inseparable than they had already been. The two of them are largely responsible for creating the Kamijo Corporation, and recruiting their fellow malcontents to form a company more in line with their shared beliefs.

Or, well, so most of them think, anyhow.
