On March 10 at the 15th Anniversary Show Roppongi Vice was unsuccessful against The Hardys in a Las Vegas Street Fight for the ROH World Tag Team Championship, The Young Bucks were involved in the match also.
On April 10, 2016, at Invasion Attack 2016, Roppongi Vice defeated Sydal and Ricochet to win the IWGP Junior Heavyweight Tag Team Championship for the second time.[7] They lost the title back to Sydal and Ricochet on May 3 at Wrestling Dontaku 2016.[8] On October 21, Roppongi Vice entered the 2016 Super Jr. Tag Tournament that began on Road to Power Struggle event. They defeated the representatives of CMLL, Ángel de Oro and Titán, in the first round.[9] After defeating Fuego and Ryusuke Taguchi in the semifinals on October 30,[10] they won the tournament by defeating ACH and Taiji Ishimori in the finals on November 5 at Power Struggle.[10] On January 4, 2017, at Wrestle Kingdom 11 in Tokyo Dome, Roppongi Vice defeated The Young Bucks to win the IWGP Junior Heavyweight Tag Team Championship for the third time.[11] They lost the title to Suzuki-gun (Taichi and Yoshinobu Kanemaru) at NJPW's 45th anniversary show on March 6,[12] before regaining it at Road to Wrestling Dontaku day 3 on April 27.[13] They lost the title to The Young Bucks on June 11 at Dominion 6.11 in Osaka-jo Hall.[14]
On July 2 at G1 Special in USA, Roppongi Vice unsuccessfully challenged The Young Bucks for the title in a rematch. Afterwards, Romero brought up a five-year plan he and Beretta had made three years earlier, which included them winning the IWGP Junior Heavyweight Tag Team Championship and the Super Jr. Tag Tournament, both of which they had already done, as well as Beretta's eventual transition into the heavyweight division. Having failed to regain the IWGP Junior Heavyweight Tag Team Championship, Romero gave Beretta his blessing to move to the heavyweight division, effectively disbanding Roppongi Vice.[15] On August 21, NJPW announced that Roppongi Vice's final match together would take place on September 16 at Destruction in Hiroshima,[16] where they defeated Bullet Club's Chase Owens and Yujiro Takahashi.[17] Both Romero and Beretta remained members of Chaos, with each transitioning into a new role. Beretta moved into the heavyweight division, wrestling in singles competition and as a part of his long-standing tag team Best Friends with Chuckie T, while Romero became a manager for the new junior tag team Roppongi 3K.
On the May 24, 2021, episode of AEW Dark: Elevation, Beretta, along with Chuck Taylor and Orange Cassidy, saved Romero from an attack by Ryan Nemeth, Peter Avalon and Cezar Bononi, briefly reuniting Roppongi Vice as their theme music played and they embraced in the ring.[18] Romero would return to AEW and on the December 8 episode of AEW Dynamite would team with Beretta's current tag team partner, Taylor, in a losing effort against The Young Bucks. After the match, The Young Bucks, along with Adam Cole assaulted the pair. Beretta made a surprise return, having been out following neck surgery, to come to their aid. After fighting off the assailants Romero, Beretta, Taylor, and the rest of the Best Friends stable celebrated in the ring while the Roppongi Vice theme music was played.
Beretta and Romero opened the February 11, 2022, episode of AEW Rampage with a match against the Young Bucks, in a losing effort. They reunited again for the March 28 episode of Elevation in a winning effort against The Factory. They would later appear on the May 18 episode of Dynamite. On the May 25 episode of Dynamite they faced off against FTR for the ROH World Tag Team Championship; however, the match ended in a no contest after a mid-match interruption by United Empire's Jeff Cobb and Great-O-Khan. This led to a triple-threat tag team Winner Takes All match between the three teams being scheduled at Forbidden Door for the ROH World Tag Team Championship, and Cobb and O-Khan's IWGP Tag Team Championship.[19] At the event, the triple-threat tag team match was won by FTR.[20] Since then, Roppongi Vice have been used sporadically on AEW programming in multi-man matches, including on the Zero Hour pre-shows of Full Gear[21] and the following year's Forbidden Door.[22]
