Kei is a young scion of a wealthy Japanese family but seems to spend most of his time jetting around Graviton City on his motorcycle. He becomes infatutated with Cko. Little does he know both Ako and Bko are vying for his attention at the same time. Kei hardly ever speaks and has an intense fondness for Coke. In the fourth movie his parents arrange for him to be married to Miss Ayumi though he remains enraptured with Cko. In the alternate universe series a brief scene in which Kei pursues a relationship with both Ako and Bko possibly at the same time is shown though this is not certain as the focus of the story shifts back to the Vs. Ako and Bko. Wikiepedia
