The narrative tension in Sunrise's modern continuation Yoroi Shin Den Samurai Troopers reached a boiling point in Episode 21, titled "Keikoku" (Warning). Directed by Yoichi Fujita, the series pushed its emotional stakes to the absolute limit as the unified front between the Samurai Troopers and the Ten Braves faced a catastrophic fracture at the hands of Ramaga.
Following the dire cliffhanger of the previous broadcast, Ramaga's commandeering of Kai's physical form proved fatal for the heroic ensemble. In a desperate bid to obtain the Shield of Hegemony, Ramaga systematically cut down Kamanosuke, Seikai-Nyudo, Isa-Nyudo, and Saizo to claim the required baptismal lives. The poignant farewell between the Nyudo brothers—exchanging a final gesture of camaraderie before perishing—left online communities in collective grief as long-awaited face reveals were marred by tragic timing.
Desperate Last Stand
As Sasuke arrived only in time to witness Saizo's final breath, the remaining four Samurai Troopers remained trapped in an alternate dimension. The narrative contrasted their bond—highlighting how former enemies spent time learning kanji, training, and sharing meals—with the grim reality of their current defeat. Sasuke's solitary defiance using a cherished origami throwing star represented a heart-wrenching attempt at retaliation, though ultimately falling short against Ramaga's foresight.
With Ramaga sealing Sasuke's life force into the Mirror of Hegemony to claim the shield, the episode appeared set to conclude on an unyielding note of defeat. However, the post-credits next-episode preview dropped an unexpected narrative twist, dropping references to parental lineage that ignited immediate speculation regarding Kai's true origins ahead of the upcoming September 8 broadcast.
