Amusement Park ~ Astaroth Chapter ~
Amusement Park ~ Vomit Chapter ~ is chapter 53 of the Boku wa Tomodachi ga Sukunai light novel series. It is chapter five of volume five.
At the park restaurant, where the Neighbor's Club gathers and eat, they discuss what they have done around the park. As Kodaka retorts on Maria's request to ride the Black Dragon again, Sena toughly declares that she is willing to ride the Black Dragon again but adds that she won't, knowing that her club-mates are frightened. Hearing this, Yozora and Sena begin to bicker until it ended with a challenge on them riding the Black Dragon together until someone surrenders and admits defeat.
After lunch, as Sena and Yozora go and compete at the Black Dragon, Kodaka and the rest go to ride numerous thrill rides and visit a haunted house. As they ride the Ferris wheel, Kodaka, who is admiring the view of the Black Dragon roller coaster from their spot, asks how Yozora and Sena are doing. Afterwards, they agree on searching for them.
Heading to the Black Dragon's entrance, Yukimura notes to Kodaka that they have found Sena and Yozora. Finding them, Kodaka is taken aback as Sena and Yozora reveal that they had ridden the Black Dragon eight times, which resulted in having them both completely exhausted and sick. As Sena declares for a ninth round, Kodaka convinces them to call off their competition. Sena and Yozora suddenly both vomit on Kodaka as they were about to declare on not losing to one another, much to Maria's disgust as Kodaka looks at them in dismay.
