At the age of 20, Chihiro Minegishi (Horie Mana) had been wandering around, taking shelter in park awnings and internet cafes. There was a special reason why Chihiro lived a homeless life. Her mother passed away due to illness when Chihiro was young, and her father, Tetsuya, had gone missing, leaving Chihiro to live a hard life all by herself. Suddenly one day, debt collectors came after her. It turned out that Chihiro's father, Tetsuya, owed 100 million yen in gambling debts, and as the guarantor, Chihiro was now being pursued for the debt. From then on, Chihiro received help from Kuni Toyota (Takashi Tsurunou), a net cafe employee with great influence in the otaku community.
