[A monster-class manga with a total of over 400,000 copies in the series has been made into a live-action version! ] I happened to meet her younger sister Sakurai-chan, whom I had only met once, on the street. Big breasts that don't even look like her (her sister) and an extreme miniskirt that seduces men... If a female student had it, she would be a demon! The main character, who has been treated as a pervert by such an eye-candy girl, is told to clear her suspicions.
