Aiko was the Tokyo cell leader until her assassination by Toru's pack. Upon their arrival, the castle received Buffy, Willow, Satsu, Leah, Rowena, Xander, Renee, Dracula, and a group of Slayers from Scotland headquarters, in their battle against Toru's pack to recover the Scythe.
After Renee was assassinated, her ashes were spread over the castle's yard. Buffy promoted Satsu as cell leader, and the two spent their second night together before her departure.
During the destructive aftermath of Twilight's creation, the squad fought the invading placenturians in downtown Tokyo. With squad leader Satsu's absence, an unidentified Slayer commanded the others to attack at the flanks of a certain demon, as its throat was inaccessible. The Twilight-empowered Angel then beheaded it, offering them a hand, as he'd been helping Slayers around the world against the invading creatures.
