They started talking online and she convinced him to join his schools chess club. Once he did he feel in love with the game, he started to worship Dispeariss for "bringing him into the light", he loved the rush of despair he felt when he would loose in a chess game to the point where he got addicted. Once he found out that Dispeariss was attending Star Shine High, he bribed a talent scout to let him into the school. Once he learned that Dispesriss was Chika, they started to create the killing game together. Kiyoshi is often Calm and mysterious. He hides his age and he believes his "true ultimate" is the ultimate despair.
