Monogatari - S04

In October of his third year of high school, Koyomi Araragi meets a transfer student named Ougi Oshino, introduced by his junior, Kanbaru Suruga. Ougi says she wants to discuss something with him. While sketching a map of Naoestu High School, she notices something strange. This oddity uncovers a hidden story-one that changes Koyomi’s school life completely. It’s a tale that exposes "what" defines Koyomi Araragi. It’s the story of the "beginning" of everything.
