Episode 6

Episode 6 refers to the sixth episode of the Null & Peta anime series.

Summary
Null and Peta are playing at the beach, with Null actually relaxing under the umbrella doing recreational math. When a crowd of grade-schoolers appears, Null runs away.

When Null passes a nearby kiosk, a female clerk named Kaki assumes she wants to buy snow cones. Null is too startled to speak properly and ultimately runs off to the beach again.

Kaki follows her, with Null's forgotten purse and two snow cones. They sit together and have a friendly chat about kelp and snow cones. After that Null, Peta and Kaki spend the afternoon with "typical" beach activities.

The episode concludes with Peta briefly adopting Kaki's nickname for Null, "Miss Apolo-giant" (orig.すまんもすー！, where すまん is a casual apology).

Trivia

 * This episode contained the first hint at the simulated world when after Kaki runs off into the background, the other people's presence flickers for a moment.
