After two and a half years of activity, the All Out unit disbanded at the All Out Final Fight event that took place on March 12, 2021.[18]
Pheromones (2021–2023)
In August 2021, Iino changed his ring name to Yuki "Sexy" Iino when he formed a new unit called Pheromones with Danshoku Dino – now going by the moniker Danshoku "Dandy" Dino – and Yumehito "Fantastic" Imanari.[19] On November 3, Iino along with fellow Pheromones stablemates, Dino and Imanari, won the vacant KO-D 6-Man Tag Team Championship by defeating the team of Sanshiro Takagi, Shinya Aoki and Yusuke Okada at the D-Oh Grand Prix 2021 II event in Ōta.[20]
In the 2022 Ultimate Tag League, Yuki Iino and Yumehito Imanari finished second of the B Block with 4 points and failed to advance to the final. On February 14 at the Ultimate Tag League event in Shinjuku, Iino beat Shinya Aoki in a Turkish oil wrestling match to win the DDT Extreme Championship, marking his first singles championship victory in DDT since his debut in August 2017.[21] On April 10, at April Fool 2022, Pheromones lost the KO-D 6-Man Tag Team Championship to Damnation T.A. (Daisuke Sasaki, Minoru Fujita and MJ Paul).[22] On June 12, Pheromones teamed with Akito (as Akito "Co-Chin" Nishigaki) at CyberFight Festival 2022, a joint event between all CyberFight brands, to defeat Shinya Aoki, Sanshiro Takagi, Yumiko Hotta and Kendo Kashin.[23] In June, Iino entered the King of DDT Tournament, defeating Mao in the first round.[24] However, in the second round, Iino lost to Jun Akiyama.[25] On July 16, Iino lost the DDT Extreme Championship to Akito in a 3-on-1 handicap match in which he was teaming with Dino and Imanari, with Sanshiro Takagi as a special referee.[26]
On March 21, 2023, at Judgement 2023, Iino challenged Yuji Hino to a KO-D Openweight Championship match at Mega Max Bump 2023. At the request of Hino, he would fight as Yuki "not Sexy" Iino and abandon his Pheromones persona and behaviour for the match. On March 31, 2023, Iino and Dino fought to a no contest against Bussy (Allie Katch and Effy) at GCW vs. DDT, a joint event with Game Changer Wrestling (GCW) held in Los Angeles, CA.[27] On May 3, at Mega Max Bump 2023, Iino lost to Yuji Hino.[28] On October 4, Pheromones disbanded. The following month, Iino, now shedding the "Sexy" moniker, entered the annual D-Oh Grand Prix competing in the A Block.[29] Iino ended the tournament with 4 points, finishing fifth of his block and therefore failing to advance to the final.[30]
Burning (2024–present)
On January 5, 2024, during the Sweet Dreams! 2024 tour, Iino saved Burning leader Tetsuya Endo from an attack by Damnation T.A. after a match. Endo then granted his request to join the Burning stable.[31] On February 7, Iino and Endo defeated Damnation T.A. (Daisuke Sasaki and Kanon) to win the KO-D Tag Team Championship.[32] On March 17, at Judgement 2024, Burning made their first defense against All Japan Pro Wrestling's New Period (Ryuki Honda and Yuma Anzai).[33] The following month, the duo successfully defended the title against Jun Akiyama and Tomomitsu Matsunaga.[34] In May, Iino entered the King of DDT Tournament but was defeated in the first round by Daisuke Sasaki.[35] On June 6, at Gleat Ver.&: Gleat×DDT, a joint event between Gleat and DDT, Iino teamed with Kazusada Higuchi and Yukio Naya to defeat Gleat's Bulk Orchestra (Hayato Tamura, Kazma Sakamoto and Ryuichi Kawakami).[36] On July 21, at Wrestle Peter Pan 2024, Burning successfully defended the KO-D Tag Team Championship for the third time against Pro Wrestling Noah's Go Shiozaki and Atsushi Kotoge.[37] The duo eventually lost the tag team title to Schadenfreude International (Chris Brookes and Takeshi Masada) on August 10.[38] On August 12, the duo defeated 1 Called Manders and Gringo Loco at Never Ending Noisy Summer, a joint event with GCW held in Korakuen Hall.[39] On September 7, Iino defeated Kanon and won a Right To Challenge Anytime Anywhere.[40] The very next day, Iino cashed in his contract to successfully challenge Mao for the DDT Universal Championship.[41]
