They were permanent fixtures on El Dorado cards. The same year of his debut in El Dorado, Oosugi debuted in Michinoku Pro as Rei, a masked character representing a spirit of the forest. Initially face, Rei was defeated by Ken45º in order to turn him a member of his heel stable Ken Gundan along Mototsugu Shimizu and Banana Senga, changing his costume from white to black. However, the stable was dissolved and Rei returned to the face side. Then Rei adopted a purple outfit and mask based in the Evangelion Unit 01 from "Neon Genesis Evangelion", having a successful feud with Shibaten. In 2008, Oosugi changed his gimmick to Yapper Man #2, taken from the anime "Yatterman". While part of El Dorado, Milanito started wrestling for Big Japan Pro Wrestling.
