Toshi is an ordinary high school student. He spends his days being cared for by a beautiful neighbor named Yuu-nee-san, who lives nearby since his parents are rarely home. Yuu-nee-san is kind and seems like a perfect adult. However, she has a hidden side: her personality completely changes when it comes to video games. For her, games are not just for fun. She gets angry, gets naked, and stops at nothing! Toshi gets caught up in her dual personality. Thus begins a surprising new erotic comedy involving games and an older sister.
