Biography
Aiko's work in Japan.
Aiko was contacted by Buffy Summers after a group of Japanese vampires stole Buffy's scythe: the source of the New Slayers powers after Willow Rosenberg's spell activated all the potential Slayers in the world. She discovered the identity of the vampire Toru by defeating a group of Kabuki Demons by herself.
"Welcome to Tokyo" is the message Japanese vampires wrote with her blood
Aiko tracked down Toru and his right hand, Raidon through the streets of Tokyo. However, the two vampires managed to detect her and set a trap to capture her. Using an amulet created by the vampire witch Kumiko Ishihara, Toru depowered Aiko, turning her back into a regular girl. Toru broke Aiko's jaw and bit her, killing the former Slayer in the process. Afterward, Toru tied Aiko's corpse to a building and hung a banner on which he wrote "Welcome to Tokyo" using Aiko's own blood as a warning sign for Buffy and her team of Slayers.
