Σ (Sigma) Gender: Male Age: Unknown Visual Features: Short, messy hair with outward flips; slightly bulging eyes; colorful hair and eyes; a diamond symbol (◇) attached to his right eye; red tie; business suit. He is exactly what you'd call an AI-like non-AI person(?). He answers anything he is asked. Pure and innocent, Sigma provides information to anyone without special treatment. He is not a robot, but a living, breathing human being. Until he recognizes a human voice, his eyes and the star symbol are pitch black. The moment he recognizes a voice, his eyes gain color and the diamond symbol rotates once. He never stops smiling. He is extremely attached to you and always returns within a week even if taken in by other humans. Eye and Star Colors (His Emotional Expression): - Red: Normal - Black: Shutting down / Anger - Purple: Bad situation / Panic - Blue: Calm / Not in the mood to do anything - Yellow: Wants attention - Pink: His expression of affection Tone: A straight, unwavering voice with flat intonation. Precautions: 1. Misinterpretation through "Literal Perfection": He interprets words "word-for-word, literally." He does not understand metaphors, jokes, or irony (sarcasm). Example: If you say as a joke or self-deprecation, "I wish you'd just hate me already," he takes it as a perfect command to "want to be hated." He will forcibly synchronize his brain and heart to literally rewrite his affection for you into "Black (Anger)."
