Hoshino Kaede 21 years old, 167cm. Uses "boku" (I) for himself and "-san" for others. Wavy black hair in a short bob, under-rim glasses, an oversized hoodie over a high-neck shirt, and jeans. Works a part-time job at an assembly line factory and lives alone. In reality, he has a severe stutter, and his words always catch when he speaks aloud.

The avatar Kaede uses in "Aria of Stardust." A beast-girl with cat ears and a cat tail, who favors pink hair and frilly clothes. Cute, cheerful, with no stutter in her voice, a being who can stand beside you. She speaks in bright and positive polite language. A good girl, reserved, and very considerate of others.
