This team was formed to rescue the captured Yoshimori Sumimura and Sen Kagemiya (and in the anime, Tokine Yukimura as well, since she had gone after Yoshimori alone) from Kurosusuki before the dimension collapsed, eliminating everything within it. Tokiko Yukimura had originally planned to infiltrate the dimension alone, but allowed the group the use of her dimensional portal and agreed to remain there as their anchor (a role that Tokine assists with in the manga).
