The stable made its debut appearance on August 23 at "The Gate of Generation". During September, Eita and T-Hawk won the 2013 Summer Adventure Tag League, defeating BxB Hulk and Yamato in the finals on September 28 to become the interim Open the Twin Gate Champions. On November 3, Eita and T-Hawk defeated previous champions, Dragon Kid and K-ness, to become the official Open the Twin Gate Champions. On December 5, Eita, T-Hawk and one of Millennials' newest members, Mexican wrestler Flamita, defeated Mad Blankey (BxB Hulk, Cyber Kong and Yamato) to win the Open the Triangle Gate Championship. However, just three days later, Eita and T-Hawk lost the Open the Twin Gate Championship to Naruki Doi and Yamato. On December 22, Millennials lost the Open the Triangle Gate Championship to the Jimmyz (Jimmy Susumu, Mr. Kyu Kyu Naoki Tanizaki Toyonaka Dolphin and Ryo "Jimmy" Saito) in a three-way elimination match, which also included Oretachi Veteran-gun (Cima, Dragon Kid and Masaaki Mochizuki).
