Formation. Under Alpha Female's leadership (September 2022–May 2023)
At Stardom in Showcase vol.2, a non-canon event produced by World Wonder Ring Stardom on September 25, 2022, the chief executive producer Rossy Ogawa was a victim of various "grim reaper masked silhouettes" who kept attacking him for unknown reasons. At the event, he established Queen's Quest's leader Utami Hayashishita, Lady C and God's Eye's leader Syuri as his bodyguards. On the other corner, Yuu who was the first silhouette and unmasked at the previous Showcase event had also established two tag partners presented under the same masks. They were later revealed to be Nanae Takahashi and Yuna Manase on the event's night as they succeeded in defeating Rossy's Bodyguard Army.[2] Minutes later, a video of Alpha Female was played, showing her criticizing the current situation in Stardom as she was announcing her return to the company on October 23, 2022, for the IWGP Women's Championship inaugural tournament. Together with Takahashi, Manase and Yuu, Alpha Female officially formed the "Neo Stardom Army" unit and declared the destruction over Stardom's roster.[3]
At Stardom Sunshine 2023 on June 25, Takahashi defeated Hanako in another passion injection bout.[19] At Stardom Mid Summer Champions 2023 on July 8, Yuna Mizumori teamed up with Waka Tsukiyama to defeat Queen's Quest (Miyu Amasaki and Hina), and Nanae Takahashi defeated Starlight Kid in another passion injection bout. Mizumori silently defected the unit to join Cosmic Angels in the process.[20] Since then, the stable officially reduced to the tag team of Nanae Takahashi and Yuu. At Stardom Midsummer Festival on August 19, 2023, Takahashi teamed up with her old "NanaMomo" tag team partner Momoe Nakanishi and Jaguar Yokota to defeat Black Desire (Momo Watanabe, Starlight Kid) and 7Upp teammate Yuu in six-woman tag team action.[21]
Due to being a Stardom unit, the members often compete in New Japan Pro Wrestling related events. On the first night of the Royal Quest II event from October 1, 2022, Alpha Female teamed up with Kanji in a losing effort against Ava White and Alex Windsor.[23] On the secind night rom October 2, she defeated Ava White in the first rounds of the inaugural IWGP Women's Championship tournament.[24]
