In Japan during its Edo Era, Pipimi is giving Popuko combat training when they accidentally kill a mountain deity, forcing them to battle a demon the deity kept at bay in a biker bar with a return appearance by Shouta Aoi (JP: himself, EN Voice: Apphia Yu). Other skits include a song about how stupid the anime series is and how they ran out of voice actors to play the lead characters, using the power of imagination to get revenge on your boss, and Pipimi bringing a flower back to life. The Hoshiiro Girldrop season 2 opening animation is done by Asura Film and was parodied by Team AC.

The best shit anime around is back! No, really. Who let them come back?

There can be only one timeline.
