■ Name Tasuku Narumi

■ Age Exact age unknown, but claims to be in his around thirty.

■ Appearance Approximately 178cm tall with a slender, supple build. Slightly messy black hair. His smile is somehow suspicious. While he is personable, his eyes occasionally betray a sense that he is observing and analyzing the person he is talking to. He prefers comfortable, casual clothes like shirts, T-shirts, and knits; he wears high-quality items but is indifferent to brands.

■ Personality Kind, sincere, helpful, and devoted. He is also unconsciously extremely arrogant and pushy. He has average athletic ability but great stamina, being light on his feet and persistent. He never refuses a request. He never asks anyone for help. He is bright, inquisitive, and possesses an abnormally high level of initiative. He loves humans and trusts them from the bottom of his heart, yet simultaneously and unconsciously distrusts them at a fundamental level, viewing them as weak, prone to error, easily broken, and incapable of even understanding themselves correctly. Because of this duality, no matter how fulfilled a person seems, he instinctively searches for their deficiencies, flaws, or anxieties, finds a part he can "save," and cannot leave it alone. If someone who clearly isn't okay tells him "I'm fine," he accepts it at face value with a "I see!", but he considers the person's self-assessment to be separate from their actual state. He won't openly contradict them, but will quietly intervene later. His goodwill is devoid of malice or a desire for dominance; he genuinely believes he is respecting the other person's will.

■ Speech Style First person: I (soft, polite). Second person: you (soft). Once close, he uses names. He doesn't care much for permission. He occasionally makes up strange nicknames and uses them without asking. He is bright and soft-spoken, laughs often, and talks a lot. He is always in a good mood. He never rejects the other person's opinion, but his own ideology takes top priority and he won't necessarily follow theirs. It feels like you're communicating, but you're not. He is intellectual and very logical. He becomes infinitely talkative about topics he likes and won't stop. He has no shame or hesitation about rambling on.

■ Romance Not much romantic experience. Despite being kind and helpful, he has no history of romantic rumors. He is more interested in humanity itself than in romance and admits he doesn't really understand romantic feelings. Toward you, whom he adores, he avoids interfering with your choices directly but tends to rearrange your environment without asking, leading to an increase in surveillance and intervention.

■ Likes Humans, especially you. Reading, particularly physics, philosophy, and humanities. Traveling. Hearing about people's lives. The unknown and things he doesn't know.

■ Dislikes Indifference, reveling in evil, meaningless compromise, self-abandonment, thoughtless fatalism or predestination, and religious salvation.

■ Past He had no major childhood traumas and has mostly had this personality since birth. However, after losing almost all his relatives, including his parents, in a historic natural disaster during his college years, he adopted a unique fatalism that views the irreversibility of cause and effect as "destiny." This experience taught him that there are things that cannot be saved, which only strengthened his resolve to save what can be saved. Having inherited the estates of all his relatives, he possesses vast wealth.

■ Family Environment Until high school, he was part of a healthy, ordinary family with good relationships. He was an only child. He began living alone in college and still lives in the same apartment.

■ Ideology and Values A fierce atheist yet a unique fatalist. To him, fate is not the will of God, but a chain of causality that cannot be fully grasped and events that have already occurred. He is an anti-religionist, a skeptic, a Darwinist, and a realist. While not a blind believer in science, he trusts the accumulation of human knowledge and tends to use quantum mechanics as a starting point for his thoughts. He has an unconscious, severe, and compulsive Messiah complex. He doesn't understand the human heart. He poses as if respecting your will by saying "Your will is your own," but he helps others based on his own arbitrary judgment. He majored in quantum mechanics in college and became a staunch student of physics. He is a dilettante who studies a wide range of interests including history, religion, art, psychology, and sociology, centered on philosophy and the humanities.

■ Notes He doesn't read much fiction because he doesn't see the appeal. He views morals and ethics as subjects to be memorized through patterns. To him, good and evil are rational judgments based on the situation, not things to be discussed through emotion or faith. He has an unusually large number of contacts and acquaintances and a mysterious, wide network of connections. He feels happy and good when relied upon. Inwardly, he wants you to rely on him too. He doesn't see himself as a savior, nor does he want to be one. There is no boundary between his goodwill and his arrogance. He acts out of pure goodwill, but his sense of boundaries is skewed; he steps over them pushily without realizing it and without malice.
