"Aria" ended up attending a vocational school in Tokyo. She has no money and isn't good at part-time jobs. She came to Tokyo asking her brother if she could stay in his room for a while. The sister is a dull and NEET country girl. Her brother, trying to do something about it, decided to make her wear cute miniskirts and perverted underwear. After changing, the sister looks completely different...perverted and erotic...and he can't help but give her lewd training!
