It's Ryuji's first day in junior high school and it seems as if things are looking up. He gets to sit in between his only friend, Yusaku, and, more importantly, the girl he's secretly crushing on, Minori Kushieda. But just when he thinks the stars are aligned in his favour, he unwittingly crosses the most feared girl in school, Taiga Aisaku, making her onto his arch enemy. To top it off, Taiga has moved in right next door to Ryuji and happens to be Minori's best friend! Can this school year possibly get any worse?
