Kevin loses his Samurizer in an attack by the Nighlok Skarf (who eats it) while out in town near the local swimming center where a swim meet is being held. There, he reunites with one of his old swim team members and begins to have thoughts that he should return to swimming, as his friend is not as good as he was, and his Samurizer is still missing. Mike calls Kevin’s Samurizer so they can track down Skarf, discovering the Samurizer is in the Nighlok’s arm. Elsewhere, Dayu finds a part of Deker’s Uramasa as she is approached by Serrator who tells her where she can find Deker so they can serve under him in exchange for Dayu’s harmonium and Deker’s Uramasa getting fixed. Dayu and Deker enter the fray with Skarf so Deker (who is wielding a different sword) may fight Jayden in his Super Samurai mode. However, Dayu and Deker end the fight prematurely by destroying Skarf (since Serrator mentioned that the destruction of Skarf can unlock his secondary power), giving the Rangers the chance to retrieve Kevin’s Samurizer. When the Nighlok enlarges, he gains a shield, forcing the Rangers to form the Samurai Gigazord for the first time, with Jayden using Shogun mode to break through the shield and destroy the Nighlok. Later, Kevin goes to the swim meet to see his old friend win after using Kevin’s advice.
