The Gathering of Many

34 people. 17 universes. 17 pairs: a boy and a girl from each one. Someone wanted these 34 gathered in one place, but how, who, and why? Will they be able to satisfy their captor enough for him or her to send them back home? Rated T for innuendos, sexual themes (and maybe encounters), language, and Sakura Kyoko, Shiguma Rika, Yuuki Rito, Hyoudou Issei and Araragi Koyomi's behavior.
