My Sister Can’t Possibly Become Like This [BlueRose]

Synopsis

■STORY

Hatori Yu is a second-year student at his academy. He lives with his accomplished older sister Ai, who serves as student council president and is famous throughout the school, and his younger sister Mii, known in the neighborhood for being reliable. Surrounded by his beautiful and intelligent sister and cute younger sister, Yu is just an ordinary boy with no distinguishing features—except for one hidden obsession he can’t suppress.

An overwhelming lust for his sister.

Peeping while she bathes, stealing her used underwear while doing chores, searching through the bathroom waste—all while being scorned, verbally abused, and kicked by his sister. Yet his desire for her only grows stronger.

One day, a mysterious creature calling itself an angel, “Archae,” appears before him.

“I’ll grant your vulgar and pitiful wish.”

With those words, Archae hands Yu a phone number. “Is it really okay if I do… that kind of thing to my sister?”

Unsure but curious, Yu dials the number…
