桃瀬 香織

Nagisa's best friend and Yuuto's natural enemy. She is the student council president and has maintained top grades since she entered the school. Her high-spirited, playful personality, and unparalleled fondness for crude jokes have made her an enemy of Yuuto, who is worried about the negative influence she may have on Nagisa. She blows his mind, when she supports their love affair. She is an indispensable ally for their anal sex escapades, preparing tools for anal development and imparting her sexual knowledge, and setting up places for sex with her own connections.
