Black Hotpot Gives Girls a Bad Smell ___（;´∀`) (闇鍋は美少女が残念な臭い（;´∀`), Yaminabe wa Bishōjo ga Zannen na Nioi（;´∀`)) is the pilot episode of the Haganai anime series. It was bundled and sold alongside Light Novel Volume 7's limited edition.

Summary
Rika then said that it is impossible as Kodaka agreed. At the far end of the table, Yozora and Sena, both visibly exhausted, asked the other to give up. Both then picked something from the hotpot and forced it in their mouth. Yozora and Sena then both suffered the consequence of the food.

Kodaka then recalled back a few moments ago as Yozora offered to have a black hotpot as the members were all happy with the idea. Kodaka then wondered what happened as he looked on and saw Maria, whose eyes were pale and mumbles that a demon is coming. Kobato then tells her brother to escape while he can since he cannot beat it.

Yukimura was just moving his chopsticks without food as he kept calling Kodaka. Rika then said that if it were food that they've been eating, it would be disinfectant, but the smell alone instantly knocked out Rika. Yozora and Sena begin the round again and both ate something. However, this time, both cannot hold it anymore and with dead eyes, both turned to Kodaka...

"You idiots ! Don't do it !"

It was to no avail as the vomit slowly tainted the memories of Kodaka. Later, Kodaka opened the curtains, revealing that it was almost night time as Kodaka sighed and began to wipe off the vomit on him saying how this unfortunate story whereby the two heroines regurgitated on the very first episode, the story of the lives of the Neighbors' Club.

The story then ends for now...

Credits
During the credits, as the Ending song plays, pictures from the light novel appeared.

After the ending song, Kodaka was shown to say that he wished to forge a strong bond with the club members, how to hone their minds and bodies to perfection and using that strength, they will bolster each others' feelings, to empower the whole.

"This is the Neighbors' Club."

Yozora then stood there, confident and said those words.

The Opening Song of the Anime then came up as fragments of the anime were shown. The story the gave a brief introduction to the characters :
 * Miss Troublesome: Mikazuki Yozora
 * Meat: Kashiwazaki Sena
 * Girl Genius: Shiguma RIka
 * Wholesome cross-dresser: Kusunoki Yukimura
 * Heterochromatic: Hasegawa Kobato
 * Young Sister: Takayama Maria
 * Protagonist: Hasegawa Kodaka

Kodaka then commented that he liked the song as Yozora said that he still has to improve it to please her. Kodaka asked how, as Yozora said that they just need to remove meat (Sena) from the song and footage as Sena angrily tells Yozora that she is insane and said that her absence improves nothing but, in fact, the anime will probably go down the drain without her.

Yozora then said that a meat like Sena is the only one who will go down the drain as Sena said that a goddess like her would never be that as Sena said that if she sang the Opening alone, it would have been perfect and would hog the top of all charts. Yozora then said that there is no way she could and tells her to think about the club and go to a fridge.

Sena asked why as Yozora said that it would remove the stink and asked Sena to appreciate her kindness as Sena said that Yozora doesn't have any.

Kodaka: "Speaking of which, what about my part ?"

Both Sena and Yozora: "YOU HAVE NOTHING TO DO WITH THIS !"

Kodaka resigned to his fate

"Hey meat, you've been playing that game all the time right ?"

"No, i did not !"

"Hmph."

And hence, the episode ends.
