Following the first season's gag action theme, the second season titled To Be Heroine features an original story and a new set of characters. You is about to leave home when she suddenly enters an incredible world. Appearing in front of her is an eight-year-old naked boy, and before she could even grasp the situation, she's attacked by assassins from a mafia group who were chasing the young boy. What was even more unrealistic for You was that the leader of this mafia was another assassin's attack. Who are those naked kids, why did her shoe turn into a warrior and above all, what kind of world did eight-year-old boy come from? Just like the first one, he's also almost naked! While trying to escape from the attackers, You loses one of her shoes and by a strange kind of magic, her shoe turned into a warrior who was able to save her by blocking the You enter?

2150 AD. The battle against the silicon-based Festums from outer space reaches a new phase. Fragments of the North Pole Mir were scattered throughout the world. Eventually, they began to act on their own as independent Mirs. Most hated humanity and attacked them, but some chose to coexist with mankind. Some with the same way of thinking existed within the human race, as well: those who were both human and Festum. They added to the chaos of the battle and brought about even more hatred.
