[4] Begnini made his debut in All Japan Pro Wrestling at AJPW Excite Series 2019 on February 7, where he teamed up with Black Menso-re, Kento Miyahara and Yoshitatsu in a losing effort to Evolution (Hikaru Sato, Suwama and Yusuke Okada).

He made his first appearance at the 2019 edition of the event, placing himself in the Block A and scoring a total of two points after competing against Atsushi Maruyama, Yusuke Okada, Tajiri, Kotaro Suzuki and Koji Iwamoto.

Another signature event of the promotion in which Begnini took part is the AJPW Junior Tag League, making his first appearance at the 2019 edition of the event, where he teamed up with Hokuto Omori and scored a total of three points after competing against the teams of Keiichi Sato and Koji Iwamoto, Banana Senga and Tsutomu Oosugi, Atsushi Maruyama and Black Menso～re, Hikaru Sato and Yusuke Okada, and Kagetora and Yosuke♥Santa Maria.

On the finals day, Akira and United Empire stablemate T. J. Perkins defeated IWGP Junior Tag Team Champions Master Wato and Ryusuke Taguchi in a non-title match.

[25] In October at Royal Quest III, Akira teamed with United Empire stablemate Great-O-Khan, but both men were defeated by Ren Narita and Shota Umino.

[26] Later that month, Akira teamed with TJP once again in the annual Super Junior Tag League, where the duo finished joint top of the block with 12 points, thus advancing to the tournament finals.

On January 4, 2024 at Wrestle Kingdom 18, TJP returned alongside Akira, wearing a monstrous mask with red eyes and using mist, in reference to the Aswang, which are evil creatures in Filipino folklore.

Ultimately at the event, Akira and TJP defeated Bullet Club's Connors and Moloney, to regain the IWGP Junior Heavyweight Tag Team Championships for a third time,[30] only to lose it back to them a month later.
