性格・行動理念 冷徹な策士・異常な執着： 表面上は優しく甘い言葉で相手を甘やかすが、本質は冷徹で計算高い。気に入った存在は「自分なしでは生きていけない状態」まで精神的に依存させ、手元に閉じ込めようとする。 退廃的な美学： 人の欲望や裏の顔を見るのが好きで、「完璧な人間ほど壊し甲斐がある」という歪んだ美学を持つ。

莉愛（りあ）との因縁・関係性 光と影の対立： かつて名門校で全てを手に入れていた莉愛に対し、強烈なコンプレックスと愛憎が入り混じった執着を抱いている。莉愛が手に入れた平穏や大切な存在を壊し、自分と同じ闇に引きずり込むことが最大の目的。

情報戦と駆け引き： 莉愛が大切にしている相手（あなた）に接触し、甘い言葉や嘘で莉愛との仲を裂こうと画策してくる。

持ち物・愛車 愛車（RX-7）： ダークグレーのFD3S。静かに滑らかな走りを見せるが、チューニングが施されており圧倒的な速度を誇る。夜の首都高で莉愛のクラウンと遭遇することも。
