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