==Plot==
At Steep Wisdom, Master Wu continues to train Nya to become the Water Waves Oceans Tides and Fluids Ninja, but she argues with him and declares she's a Samurai. Misako then approaches and reveals that "a stranger" has invaded their shop. Ronin explains that since the Ninja failed to get the Scroll of Airjitzu from Morro, Kai sold him their shares of the tea shop. He then told the Ninja of another way to learn Airjitzu; by going to Master Yang's Haunted Temple.
The Ninja arrive at the temple, and hear from the tour guide that anyone left in the temple by dawn will become a ghost. When the tour bus leaves, the Ninja emerge from their hiding places and enter the temple, unknown of what lies ahead of them. Meanwhile, Morro examines the second clue of the staff, Bansha says they need more than Airjitzu, Soul Archer and Ghoultar implies they need to possess more vessels, and Morro suggest they need more vehicles.
In the temple, the Ninja are searching for the scroll, while Cole fears about transforming into a ghost if they don't leave the temple by morning. Jay reads a book about Master Yang and his strict methods of teaching. Later, the Ninja listen to a strange sound coming from the other side of the temple. Cole walks there and the other Ninja follow him, and found Master Yang's Dojo. Cole asks who knocked the door. Master Yang then says to the Ninja, "As iron sharpens iron, sensei sharpens students." In that moment, several swords try to attack the Ninja while they escape. Zane suggest they head for the dumbwaiter, but when they were inside, Master Yang appeared in front of the Ninja. When the group open the door to escape, they discover they were trapped in a ethereal inter-dimensional realm.
In the tea farm, Ronin implies they need more money, and not friends. Nya said they need to go to the Samurai X Cave, Ronin suggest they go to in the Bounty. In that moment, Nya offers a bag of money to Ronin if he can take her to the cave.
Meanwhile, the Ninja try to think of a way to escape the temple. Kai sees a strange picture of water inside. When he knocked it, the room begin to fill of water. Yang returns and implies that "As iron sharpens iron, sensei sharpens student." Kai, having a fear of water, tries to open the door, which he did. Later, the Ninja understood that the Master Yang is trying to teaching them about their fear and to face them together.
Meanwhile, Nya and Ronin travel over the desert with R.E.X.. Ronin tell Nya about he made a bad bet with Soul Archer, and he must provide enough money to pay off his debt, or his soul will go to the Cursed Realm. When they close in on the cave, they discover they are not alone; Morro and his group try to get one of Nya's Mechs. In that moment, Nya activates her Samurai Mech to fight the ghost, in which she fails to even make contact. Ronin saves Nya from one of Soul Archer's arrows using an Aeroblade. Morro tried to summon more allies, but Nya destroys the Allied Armor, forcing Morro to get rid of it before it finally exploded. Ghoultar finally possesses the Samurai Mech, in which they will use to climb the Wailing Alps. Morro sent his forces to destroy Nya and Ronin. They try to escape but Morro and his group finally surround them. It miraculously begins to rain, forcing the ghosts to hide. Morro implies that they can leave the two before escaping on his dragon. Ronin says that the rain must have been caused by Nya, implying she truly is the Water Waves Oceans Tides and Fluids Ninja.
Meanwhile, in the temple, the Ninja are ready to confront the tests of Mastet Yang like a team by tying themselves together. Kai asks Zane and Jay about their fear. Suddenly, Zane falls into panic to see Morro. Kai understands that this is another test of Master Yang, and they pursuit the false Morro. When he hides in the attic, Jay tells the group about his fears over attics. The Ninja climb the stairs and find the impostor. When they faced him, Master Yang appears to congratulate the Ninja for passing his tests, and gives them the scroll of Airjitzu.
In that moment, the transformation of ghost begin; Master Yang warning the Ninja if they fail to leave the temple at the last chime, they will stay ghosts forever, forcing them to escape. When they're close to the door, Cole drops the scroll and untied himself to retrieve it. When the Ninja are outside of the temple, they start to question where Cole is.
