The rangers start off in a battle in their zords against giant moogers. Later, back at the mansion, the rangers start to talk about a way to stop the nighlok when Jayden points out the Black Box. Jayden doesn’t think it’s a good idea since no one has ever completed it when Emily says that maybe Antonio could do since her programed the claw zord and even though he has lack of symbol power training and to Jayden’s dismay, they agree. Jayden takes The Rangers to the Tengen Gate where they meet the gate’s guardian, Daisuke, to hand them the Black Box- a weapon made by the first Red Samurai Ranger centuries ago, but was never finished. Daisuke tells the Rangers a folk tale about a Nighlok king who turned a woman and the man she loved into Nighloks. While Xandred is incapacitated regenerating in the Sanzu River, a Nighlok named Arachnitor tries to overthrow him and tries to force the sealing symbol from Jayden.
