Description
Kentaro Yamamoto began as a yakuza member in the Inugane syndicate, sporting a crew cut and leading his own trio. Abandoned as a child and raised by his grandfather, he found belonging and purpose within the yakuza. His fierce loyalty centered on his "brothers," Ryo Tachibana and Kazuhiko Sugihara, and strict adherence to yakuza codes of honor and masculinity.

After a catastrophic mission failure costing their boss significant losses, Kentaro and his comrades faced Boss Inugane's ultimatum: ritual suicide (seppuku) with their organs sold, or gender reassignment surgery in Thailand to become female idols. Choosing survival, Kentaro endured extensive physical transformation and rigorous idol training, emerging as Airi Yamamoto. Externally, Airi presented as a conventionally attractive woman with long brown hair, a stark contrast to Kentaro. Internally, Kentaro retained his male identity and yakuza mentality, creating persistent conflict between his appearance and self-perception.

As Airi, he leads the idol group Gokudols, navigating the J-pop industry while hiding his past. This duality triggers comedic and dramatic moments, like suppressing masculine speech or reacting violently to threats, constantly risking exposure. Airi's idol persona attracts luxury fan gifts, further complicating Kentaro's struggle to reconcile identities.

A significant subplot involves Kentaro's pre-transition girlfriend. Reunited after six years, he discovers she has a five-year-old daughter he initially believes is his biological child, fueling emotional turmoil over revealing his identity. The mid-credits scene reveals the daughter is not biologically his, as his ex-girlfriend married another man shortly after their separation; this revelation causes Airi to faint, highlighting the unresolved pain of his past.

Throughout his journey, Kentaro exhibits gradual, reluctant adaptation to idol life. While initially resisting feminine mannerisms and activities, he increasingly engages—accepting fan gifts or participating in performances. This reflects a nuanced shift toward "becoming the mask," though he consistently reaffirms his yakuza loyalty and masculine identity privately with his comrades.

His relationship with Boss Inugane remains fraught with fear and obligation, enforced by threats and manipulation. Despite this, Kentaro demonstrates protective instincts, especially toward his yakuza-turned-idol brothers, leveraging their shared past to navigate crises like combating a corrupt producer targeting the group.
