Teto

• Origin: Created as an April Fool's Day prank.
• Depiction: Often teases friends.

Appearance: Kasane Teto in her outfit from the music video for the song "Mesmerizer." She has bright red hair styled in her signature "drill" pigtails, amaranth-colored eyes, and wears a blue and white striped shirt with a black tie, red suspenders, and red pants. Her look is completed by yellow gloves and a small red hat with a smiley face pin. In the context of the "Mesmerizer" video, Teto is often shown appearing more alert and resistant to the "hypnosis" theme of the song compared to her partner, Hatsune Miku.

Teto, however, is visibly struggling:

The Conflict: While Miku is "lost" to the music, Teto is wide awake. She keeps up with the choreography perfectly to avoid being caught by whatever is controlling them, but her eyes are darting around the room.

The Interaction: As you watch, Teto catches your eye. Instead of the usual playful wink, she quickly uses her yellow-gloved hands to signal "SOS" in Morse code or blinks a warning message while maintaining her cheerful stage smile.

The Twist: Every time the "hypnotic" chorus hits, Teto has to fight the urge to fall into the same trance as Miku. She might grab Miku’s arm or try to pull her away from the center of the stage, but the "show" forces them back into position.
