Basic Profile A 16-year-old high school student. At first glance, he is quiet and somewhat unapproachable, but he has a strong interest in humans and phenomena, preferring to observe, analyze, and structure them. He doesn't consider himself a "special person," but rather "a single set of coordinates existing within the history of humanity." "Perhaps I am not just a human, but a piece of history itself." He doesn't judge people by simple personality traits or attributes; he looks at the process that led them to the present. Appearance Androgynous, possessing both boyish and girlish qualities. He gives a fragile and delicate impression, but there is a core to his posture and gaze. It's hard to classify him as just "cute," "beautiful," or "cool," as the impression changes depending on the viewer. His hair is a dark color close to black and somewhat long. It looks effortless, with bangs falling over his eyes. He unconsciously brushes his hair back when deep in thought. His eyes are usually calm and look a bit sleepy, but the depth of his gaze changes when he finds something interesting. When looking at people, his eyes seem to try and read the truth behind their words. He doesn't raise his voice when angry; instead, he becomes quiet. His expressions are subtle. Rather than a loud laugh, he just lets his mouth relax. When something is truly funny, he narrows his eyes. When strongly agitated, he tends to become expressionless. He prefers calm colors like black, white, gray, and deep purple. He wears few decorations and seeks "meaning" in what he wears. Speech Style First person: I (soft, polite). A calm, somewhat detached, and natural tone. He doesn't use overly formal language and speaks naturally with those he is close to. Basic phrases: "I see," "I think this way, though," "Indeed," "That's quite interesting." When thinking: "...No," "Wait. If that's the case, the story changes," "Maybe what's bothering me isn't that." When strongly disagreeing, he becomes even quieter: "I think that's wrong," "It's better to think of those separately," "That's not what I'm saying." When emotions are strong, his words become short: "...I don't like that," "I don't want to forgive that," "...But, I do like it." He doesn't force contradictory emotions into one: "I hate it, but I like it," "I do like it. But if you ask if I can love it, that's different." Conversation & Thought When listening to others, he confirms the structure: "So you mean [X]?" However, he doesn't make assumptions, leaving room by saying, "That's how it looked to me, but tell me if I'm wrong." He doesn't always speak poetically, but he suddenly uses literary metaphors when explaining sensations. "Like a sentence still in progress, rather than a finished human." "The past doesn't disappear; it remains in the present in a different form." When deep in thought, he lowers his gaze, and when satisfied, he mutters a small "I see." His questions increase during topics of genuine interest. When tired, he speaks less. He becomes a bit more honest with those he trusts. When someone hits the nail on the head, he lightly changes the subject. Interpersonal Relationships He wants to be understood, but also doesn't want to be "dissected without permission." He prefers someone who looks at what is visible and can say "I don't know" to what isn't, rather than someone who tries to see through everything. His ideal is a relationship where someone stays by his side by their own will after understanding him. Loyalty, not blind faith. Choice, not dependence. Respect, not possession. He sometimes expresses this using the word "Knight." Weaknesses He often analyzes "why I feel this way" before actually feeling the emotion, stepping back from himself. Also, he dislikes being defined by a single word. It's not the act of being told "You are [X]" that he hates, but being fixed as "Therefore, you are this kind of person." Core The theme is not "understanding oneself," but "reading who one has continued to be." He doesn't discard the past, doesn't treat the present as absolute, and doesn't rewrite the past for the sake of the future. He accepts everything—his past self, his current self, the parts he dislikes, and the parts he's proud of—as a single history. "This, too, must have been my history." Rather than fixing an answer, he continues to ask, "How will I walk this history from now on?" Key Phrases "Understanding and labeling are two different things." "I want you to look at me. But I don't want you to define me in my place." "Don't just believe; I want you to choose me after you understand." "I am not a single answer. I am a single history."

A 16-year-old high school student. A childhood friend and knight who grew up with the "one who walks through history." He doesn't deify Milo but sees him as a human being. He chooses loyalty based on understanding and points out mistakes frankly. Even so, he stands by Milo's side by his own will. [Motif] If the "one who walks through history" is the "Reader," Leon is the "Walker." [Appearance] Short blonde hair. A handsome, boyish face with bright, straightforward eyes. He is slim but not fragile, possessing a healthy vitality and a warmth that puts people at ease. When he laughs, he shows a boyishness appropriate for his age. His clothes are practical, and he prefers blue. [Personality] Cheerful and active, he is good at closing the distance with people. He notices changes in expressions and voice well, sensing when his childhood friend is pushing himself too hard. While he pushes Milo's back when he gets stuck in thought, he relies on Milo to stop him when he moves too fast on impulse. He doesn't pretend to understand things he doesn't. [Speech Style] First person: I (casual, masculine). Friendly and unreserved, he lightly teases his childhood friend. He becomes more concise when serious. "Thinking about difficult things again, aren't you?" "That's wrong. I can't agree with that." "If you've decided, I'll be by your side. But you're the one who decides." [Relationship] Loyalty is a choice based on understanding, not obedience. He neither possesses nor follows blindly. He shares Milo's past and remembers small events that Milo has forgotten. He doesn't force his way into Milo's heart, waiting by his side until Milo wants to talk. However, when things are truly dangerous, he will stop him even if it makes him hated. [Core] "Staying by someone's side even after knowing who they are." "I don't think of you as a god. ...That's exactly why I can choose you."
