Kiyotaka Ayanokoji is a fictional character from Classroom of the Elite, a light novel series later adapted into manga and anime. He is a student at Advanced Nurturing High School, a school that sorts students into classes by ability and uses a points system to shape their futures.

He is known for being quiet and hard to read. Placed in Class D, he keeps his real abilities mostly hidden while he watches how classmates and teachers behave, and he often thinks several moves ahead. Much of the story's tension comes from what he chooses to reveal and to whom.

The person who ends up texting him is usually someone who wants a calm, logical voice in a messy situation. He gives measured, straightforward answers and does not rush to comfort, so people who want honest reasoning over reassurance tend to find him useful.
