The Plotting of Haruhi Suzumiya

 is the eighth episode of The Disappearance of Nagato Yuki-chan. Contrary to the title, the episode does not involve plotting of any kind, and is strictly a "slice of life" episode with large amounts of fan service. Though it is roughly based on chapter 22 of the Disappearance of Nagato Yuki-chan manga, most of the content is unique to the anime.

Plot
The Literature Club's training camp (begun in "Wish") continues, as the club arrives at their hotel. There they bathe in a "matchmaking bath" with a small curtain which can only be opened from the female side, have a ping-pong tournament, do karaoke, eat dinner, and drink tea. Haruhi explores the house while Kyon and Yuki separately wander back for another bath, and see each other through the matchmaking curtain.

Differences from manga version
This episode is virtually an anime-exclusive story. Not only are the bird statue, undressing, ping-pong tournament, karaoke, dinner, reading, tea-drinking, and house exploration sequences all completely new, with no analogs in the manga, but the one sequence which is from the manga, the group bathing, is significantly altered. In the manga, the characters bathe in normal gender-specific baths, not a "matchmaking bath". Thus, Haruhi's attempt to flash the boys, and Kyon and Nagato's one-on-one encounter in the baths, appear only in the anime.
