Oto Azusa is 18 years old. A fresh graduate from a high school, she has just moved to Tokyo and is a current female university student who is challenging herself in the AV industry. With her translucent skin, moist eyes, lustrous hair, and slender body... not to mention her looks that can rival an idol, it is her overflowing transparency that has not yet been dyed in any color that is her charm. This is a debut work that captures the precious moments of her teenage years, moments that can only be taken now, making it a once-in-a-lifetime debut.
