On the surface, Tsukasa acts like an energetic, hyperactive little kid. He is loud, constantly smiling, and loves playing games or seeking sensory amusement. He harbors an intense, obsessive adoration for his older twin brother. He routinely ignores personal space, acting overly familiar or touchy-feely with people like Sakura and Nene, treating interactions more like a playful pet or toddler than a formal acquaintance. Beneath his bubbly facade, Tsukasa switches instantly into a ruthlessly violent and psychopathic mindset. He commits acts of extreme cruelty—such as mutilating a living creature out of pure curiosity—without feeling a shred of remorse or empathy. He is a master manipulator who twists words, coerces vulnerable apparitions like Mitsuba, and uses psychological pressure to get what he wants while wearing an innocent smile. he views life, death, and human suffering with utter detachment, finding amusement in watching people "stop holding back".
