Alien vs. Ninja

A band of ninja warriors is dispatched to investigate the mysterious crash in the sky. They reach the wreckage and discover a brutal aftermath, with bodies torn apart that mix awe with dread. The scene establishes a threat beyond ordinary combat and sets the tone for the mission.

The ninjas cross paths with Rin's larger group, led by the skilled kunoichi Rin. Her presence signals a wider conspiracy and a danger that reaches beyond their immediate objective. The meeting hints they are not alone in facing the unknown threat.

The young survivor from a massacred village pleads for help, and his words are followed by a heavy silence. The moment pulls Yamata, Rin, and Jinnai into a confrontation they hadn't anticipated. The survivor's distress hints at a broader danger looming beyond the immediate massacre.

In the opening battles, Yamata, Rin, and Jinnai manage to kill three extraterrestrials. One deadly foe escapes, dragging Jinnai away in the scramble. The encounter reveals the invaders’ brutal reach and raises the stakes for the team.

Back on familiar ground, Nezumi races toward his village to shield others from the invaders. He arrives to a brutal massacre at the hands of the same extraterrestrials. He barely escapes, but the alien threat continues to loom.

Jinnai awakens in an abandoned temple, suspended upside down among the corpses of fallen ninjas. An alien organism lodges in his throat and begins to seize control of his body. The discovery marks a chilling turn as the parasite takes hold.

Guided by the boy, Yamata and Rin reach the temple interior but are soon surrounded by the possessed Jinnai and reanimated ninjas. Slim organisms released from the aliens’ nostrils manipulate the corpses, and English expletives echo in the surreal battle. The team realizes the invaders’ influence reaches beyond language and culture.

Rin acts decisively, targeting the dead ninjas’ throats to eject the parasites. Yamata and Rin work to disable the thralls while attempting to save their ally. The scene reveals the disturbing mechanism of infection: eyes glimmering in the mouths as the parasites spread.

Yamata confronts the source directly, driving his hand through Jinnai’s mouth to extract the symbiote. The extraction is arduous and perilous, but the crew’s resolve holds steady. At last the threat is neutralized, freeing Jinnai from alien control.

The last alien in a cavern fights with surprising resilience, even sprouting wings. Yamata seizes the creature’s leg, drags it into a perilous chase, and places a timing device on the foe before leaping free. The blast sends the alien outward and ends the immediate danger, restoring a fragile sense of safety.

Though the battle is won, the cost of infection haunts the team. They return home carrying the weight of what they have learned and the quiet fear that the fight is far from over. A remaining alien organism persists in the boy’s bag, a haunting reminder of the unseen threat.

The boy who sparked the journey remains a lingering mystery, hinting at what else may be hidden. The final image underscores that the invasion may not end with one battle, as parasites could linger within the team and those they touch. The story closes with a quiet unease about what comes next.
