Following The Guerillas of Destiny's ejection from Bullet Club at No Surrender Hikuleo began to become more aggressive to stable leader Jay White, who was responsible for kicking out Hikuleo's brothers. This led to Hikuleo answering White's "U.S of Jay" open challenge at Mutiny in April 2022, however White defeated Hikuleo, who gave White the "too sweet" gesture post-match, confirming his loyalty to Bullet Club.[24] At Windy City Riot, Hikuleo teamed with his Bullet Club stablemates and Scott Norton, losing to United Empire.[25] Hikuleo teamed with White, to defeat Kazuchika Okada and Rocky Romero of Chaos at Capital Collision in May.[26] Hikuleo was scheduled to compete in an 8-man tag-team match at AEW x NJPW: Forbidden Door, teaming with Bullet Club stablemate El Phantasmo and one night only members The Young Bucks against Darby Allin, Sting and Los Ingobernables de Japon members, Hiromu Takahashi and Shingo Takagi, however it was announced that Takahashi wouldn't be able to compete at the event, due to suffering from a fever, so the match was made a six-man tag-team match, without Hikuleo.[27] Despite this, Hikuleo appeared at the event in the corner of Bullet Club. Despite interfering in the match, Bullet Club was defeated by Sting, Allin, and Takagi at the event.[28] In September, Hikuleo made his return to Japan at NJPW Burning Spirit teaming with Kenta and Taiji Ishimori to defeat Togi Makabe, Tomoaki Honma and Kushida.[29] Later in the Burning Spirit tour on September 25, Hikuleo betrayed Bullet Club by attacking Jay White and siding with Tama Tonga, turning face and joining the Guerillas of Destiny stable with his brothers Tama Tonga and Tonga Loa along with Jado.[30] On January 4, 2023, at Wrestle Kingdom 17, Hikuleo competed in the New Japan Rambo match, but failed to last till the final 4.[31]

Hikuleo appeared in the crowd on Night 2 of Fyter Fest in July 2021, watching the IWGP United States Championship match between Jon Moxley and Lance Archer, thus making his All Elite Wrestling (AEW) debut. After Archer's victory, Hikuleo entered the ring to have a stare-down with the victor, hinting at a future match between the two.[45] The match was scheduled for the following week at Fight for the Fallen, where Hikuleo, who was accompanied to the ring by his father King Haku, lost to Archer.[46] Hikuleo appeared on the August 11, 2021 episode of Dark, defeating Thad Brown.
In summer 2021, Hikuleo began making appearances in another NJPW partner promotion in the United States, Impact Wrestling. By autumn 2021, he was listed as a member of the Impact roster,[48] and he, Chris Bey, and El Phantasmo established themselves as a U.S. based branch of Bullet Club in Impact Wrestling.[49] Hikuleo teamed with Bey in his Impact debut, defeating FinJuice at Victory Road.[50] On the October 21st episode of Impact!, Hikuleo and Bey faced off in a #1 contendership match for the Impact World Tag Team Championship, but the match ended in a no contest. Therefore, at Bound for Glory, a three-way tag-team match was set up between the two teams and Tag Team Champions, The Good Brothers with the titles on the line. At the event, The Good Brothers retained the championships.[51] At Turning Point in November, Bey and Hikuleo were once again unsuccessful in capturing the Impact World Tag Team Championships from The Good Brothers.[52]
