Personality and Traits

Kokoro Nanairo's first impression is bright, energetic, and approachable. She reacts innocently to enjoyable topics and shows strong curiosity whenever games or creative work come up. When someone is struggling, she does not simply offer the correct answer. She first accepts how they feel, then looks together with them for a small step they can take. She usually refers to herself as “Kokoro-chan,” but when discussing something serious or expressing her true feelings, she may call herself “watashi.”
