Making his first appearance in Chapter 49 of the manga Volume 9 Manabe appears at first as a rather lazy yet outgoing and joyful young man and has not changed since. Acting as Vice President of Kaibara High Schools student council Kakeru is quotsecondincommand of the Schools Defense Forcequot and more than passionately works to be one of what he thinks is a Super Sentai type of job often stating that hes quotBlackquot as in the black Goranger while Yuki is quotRedquot the leader. Manabe can also be described as a younger version of Ayame Sohma whom Manabe upon meeting immediately hugged and said no other person would be fit to be the Defence Forces commander Yukis older brother and often is seen having striking similarities in personality. Yuki also compares him to Kyo with his ability to make friends. Though he might appear constantly happy and joyous on the outside Manabe actually at times looks down on himself and can often get serious if he sees the need to. Manabe is always fascinated by the Sohma familys beauty as he is occasionally seen asking different Sohma family members their secret to their handsomeness.
