In a deep, remote forest, a blond-haired girl runs amidst heavy rain and wind. Some pursue her, while others extend a hand to help her. As various motives tangle together, the girl, named Sana, makes her flight to the outside world for the first time in her life. In the end, Sana arrives at the bustling district of Kabukicho in Tokyo's Shinjuku Ward. In a convenience store there, she meets Kashimura Zoroku, the quintessential "stubborn old man."
The younger can call a bow, while the

يمكن للأخت الصغرى أن تستدعي قوسًا، بينما يمكن
 .للأخت الكبرى أن تستدعي أيّ شيء ذا سلسلة

La sorella più piccola
A mais nova pode usar arco e flecha,
Младшая умеет призывать лук,
а старшая все предметы с цепью.
