Unaired episode bundled with the first Blu-ray/DVD volume of W'z.

Bundled with the limited edition sixth volume of the manga. It will be between 10 to 15 minutes long and will adapt the events of the first volume. The hero and author of Sanzoku Diary is Okamoto Kentarou. When he was young, he lived out in the country, and he knew an old man who was a hunter. In 2009, Kentarou was inspired to leave Tokyo and return to Okayama Prefecture to become a hunter himself. Using an air rifle and traps, Kentarou hunts, prepares, and eats various animals. The manga covers all his hunting-related activities in close detail.

On her way to school one day, Suzume Iwato stumbles upon Souta Munakata, a young man searching for abandoned areas. The high school girl directs Souta to a nearby ruin, but out of pure curiosity, she herself decides to head to the same destination. Once there, Suzume discovers an isolated door with a dreamlike universe lying beyond it—a place that she can see and feel, but not enter. A strange stone rests on the ground nearby, but it turns into a cat-like creature and scurries away when Suzume lifts it. Suddenly afraid, she heads back toward her school, not realizing that her act of leaving the door open will have consequences. With the "keystone" released, the evil within the other universe can now freely escape and wreak havoc throughout Japan. Intending to correct her dangerous mistake, Suzume joins Souta—whose true goal is to prevent evil from festering—in finding and locking all open doors before the country is destroyed.

Six short movies featuring the daily lives of Chisato, Takina, and their friends. Each movie will have a different director and storyboard.
