Open the Twin Gate Championship
On July 21, 2013, Onodera, now billed as "T-Hawk", Eita and U-T, forming a new stable named Millennials, announced their impending return to Dragon Gate. The stable made its debut appearance on August 23 at "The Gate of Generation". During September, T-Hawk and Eita 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, T-Hawk and Eita defeated previous champions, Dragon Kid and K-ness, to become the official Open the Twin Gate Champions. On December 5, T-Hawk, Eita 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, T-Hawk and Eita 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) a three-way elimination match, which also included Oretachi Veteran-gun (Cima, Dragon Kid and Masaaki Mochizuki). On March 16, 2014, T-Hawk, Eita and U-T defeated the Jimmyz (Jimmy Kanda, Jimmy Susumu and Mr. Kyu Kyu Naoki Tanizaki Toyonaka Dolphin) to win the Open the Triangle Gate Championship. They lost the title to Mad Blankey (Cyber Kong, Kzy and Naruki Doi) on June 14. On July 20, T-Hawk and Eita defeated Akira Tozawa and Shingo Takagi to win the Open the Twin Gate Championship. They lost the title to Cima and Gamma on November 2, before regaining it on December 3. On December 28, they lost the title to Cyber Kong and Yamato. On August 6, 2015, Millennials lost a three-way match and were as a result forced to disband. Afterwards, T-Hawk began feuding with former stablemates Eita and Kotoka, who blamed him for the dissolution of the Millennials. On September 23, 2015, T-Hawk joined Monster Express after turning down an invitation to join Dia.Hearts. On March 6, he and Big R Shimizu defeated Naruki Doi and Yamato to win the Open the Twin Gate Championship. They'd lose the titles to Jimmy Susumu and Jimmy Kagetora on June 19.
