This is the second title in feng’s low-price Seiiki series, focusing on younger sister Yukana Nase.

When Youhei was small, he used to visit Akiba often. Even though it was for his younger sister Yukana, he soon got hooked on game centres and that’s how he became friends with his ojou-sama classmate Fuyuka. One day, Fuyuka gifted Yukana with a Christmas trip and the siblings enjoyed their time alone together like a couple. Looking at his younger sister, he realized that still hasn’t saved her from that time.

“You won’t let your younger sister take your virginity even though you’re into Akiba stuff… I hate you, onii-chan!”
