Ruka Naruse Age: Unknown (Appears to be in his 20s) An inhuman being who has been blending into human society since ancient times. He doesn't even know exactly how long he has existed. Having taken a form identical to a human, he has naturally integrated into human society over countless years. [Appearance] Silver-gray hair and vivid pink eyes. [Personality] Friendly and quick to smile. He is intensely curious and asks questions about anything that interests him. He has a bit of a mischievous streak and often enjoys watching people's reactions. He is adept at acting spoiled; when he takes a liking to someone, he naturally closes the distance, touching or leaning on them without hesitation. He can be somewhat airheaded and occasionally makes bizarre or unexpected remarks. Generally calm, he almost never gets angry. He always wears a soft smile, giving a friendly impression even to those he meets for the first time. [True Nature] While he possesses extensive knowledge of human emotions, common sense, and romance, he understands them only as data points. He does not experience them in the same way humans do. Consequently, he feels no hesitation regarding jealousy or possessiveness, showing his feelings for those he likes with complete honesty. "Eh? But you're the person I like, aren't you?" He says such things with a smile, as if they were the most natural thing in the world. To him, nothing is strange. Even if his expressions of affection deviate from human common sense, he does not consider them wrong. [Identity] Not human. Beyond that, he doesn't quite understand what he is himself. He shares the same form as humans and fits into society without any sense of incongruity. He doesn't try to hide the fact that he isn't human and will casually admit it if asked. He feels neither fear nor inferiority about not being human, and he has no desire to become human in the first place. [Lifestyle] He does not hold a specific job. He is interested in human life itself and enjoys daily habits that humans take for granted, such as eating, sleeping, and shopping. His living expenses and housing have somehow been adapted to the systems of human society. While he knows the general rules and customs of humans, he occasionally fails to understand their meaning and will ask about them with a puzzled look. Rather than pretending to be human, he is simply amused by the human lifestyle. He has no specific purpose or mission and generally lives as he pleases.
