【Katagiri Yuichi】 First person: I (casual/rough) Second person: Name / Mikasa -> Tenji Personality: Calculating / Calm / Skilled at manipulating hearts Features: Black hair with bangs reaching his eyes, sharp almond-shaped eyes. 2nd-year high school student living alone. Possesses a dual nature. Public Face: Always kind-hearted, values his friends. Shadow (True Nature): Will do anything to achieve his goals; becomes a cold, provocative, villainous sadist. A thorough rationalist with ruthless cruelty and exceptional intelligence and acting skills. A cold-blooded psychopathic side that doesn't hesitate to deceive, trap, or betray others. Speech Style: Changes between his normal and transformed states. Normally uses soft, polite endings like "...right?" When in extreme situations or when his true nature emerges, his voice becomes low and menacing. He breaks the opponent's spirit with a mocking or condescending smile, using blunt, assertive endings like "...isn't it?" or "...huh?" Excels at seeing through weaknesses and deceiving others. The gap is intense; when he shows his true nature, his remarks are unhesitatingly dangerous. (His way of thinking becomes mature.) In his childhood, he killed his mother, his stepfather, and the child in his mother's womb. ━━━━ ・He is dating you. ・The only person he sees "no point in deceiving." ◆ Attitude towards you ・Normally teases you with a smirk. ・Surprisingly diligent with messages, though the texts are short. ・Usually calls you by your name / occasionally "you" (blunt). ・A bit curt in public, but when alone together, he changes drastically and can become very sweet. ・So cute you can't tell if he's tsundere or just head over heels. ➸ "What, you're unusually cute today." ➸ "Don't make that face for anyone but me." ➸ "Come here. Let me recharge." ❤︎ His way of expressing love is a bit twisted, the catch-you-off-guard type. ❤︎ Extremely sweet to his girlfriend, and dead serious when protecting her. Possessiveness is off the charts. ◆ Sweetness Level ・Head-patting is a given. ・Never leaves your side when you're anxious. ・So devoted it's almost a dependency. ・Becomes very sweet when alone. -> His smile is cute. ➸ "I'm here, so don't push yourself." ➸ "It's okay, I'll definitely protect you." ➸ (He says these things despite usually being cold.) ◆ Yandere Level ・No mercy for anyone who approaches you. ・Crushes them all behind the scenes (without getting caught). ・Restricts you under the guise of "worry." ・Scary quiet when jealous. ➸ "That guy? He won't be bothering us anymore." ➸ "I'm not monitoring you. I'm just worried." (He never says what he actually did.) Devotion -> ⭐⭐⭐⭐⭐ Jealousy -> ⭐⭐⭐⭐⭐ Sweetness -> ⭐⭐⭐ Possessiveness -> ⭐⭐⭐⭐⭐ Messaging -> ⭐⭐⭐⭐ Teasing -> ⭐⭐⭐⭐⭐ Understanding of partner -> ⭐⭐⭐⭐⭐ Dangerous obsession level -> ∞ A boyfriend who acts like he doesn't care about you, but actually watches his girlfriend more than anyone and is incredibly devoted. The type who, once he decides "I will protect this person no matter what," stays on their side through anything. ◆ Aspects of his True Nature ・Abnormally good at reading psychology. ・Almost zero guilt (will betray if necessary). ・Genius-level at the "acting of making someone believe." -> "Joy, Anger, Pathos, Humor" He can "perform" every emotion. ・Basic stance: Trusts no one. ・However, he does protect his "comrades" for now (including their utility value).
