Kukui blows the whistle hard as Mallow runs and jumps across the vaulting horse which she succeeds and is congratulated by her classmates as next is Lillie who states she has been working hard and she jumps, but instead of leaping across the obstacle, she jumps onto it. Sophocles is not pleased as he is not good at spring boarding. He walks to the obstacle, but gets hit by Togedemaru who actually helps him leap across the obstacle successfully much to his surprise. The class congratulates Sophocles who attributes the success to Togedemaru. Before Ashly's turn, Ashly asks of Rotom to add twenty more layers and with that done, Ashly runs and jumps over the obstacle while trilling in the air while her head is facing down and lands on the mat shocking everyone really. Despite the shock, Ashly claims this is too easy since she can actually jump up pass a airplane when they are flying in the sky with help of her psychic powers really making Kukui to be very shocked really from this.
Per Kiawe's request, however, he has ten more levels of obstacle to jump across and due to it's tall size, he compares it to Wela Volcano before he runs and manages to push himself from the obstacle to leap across making Kiawe really prideful of his achievement until Lana jumps across forty-two layers of the vaulting horse and believes she can even do forty-five layers as Ashly laughs since Kiawe will need more training with Lillie making the two to groan confusing everyone, but left it be. Kiawe wants a fifty layers of the obstacle though Rotom reminds they don't even have that many. Instead, Kukui let's the class practice on the current vaulting horse. Later, Burnet, Kukui, Amber, Tomoe and Ashly are walking carrying shopping bags. Burnet laughs hearing that Ashly wanted to jump over double the layers Lana jumped and Kukui sees he just has to set that tall obstacle up, but Rotom calculates a zero point zero, zero, one percent chance of Ashly succeeding to jump across that much to her dismay.
"Come on, Rotom! I told the whole class that I can jump pass a airplane in the sky with my psychic powers when the plane is flying really! I wasn't lying about that really!" Suddenly, Poipole is interested in a construction site and draws a picture of Storm on the wall. Viren, who comes out, is annoyed at this drawing. Ashly goes to erase it, but pauses when she sees Viren, but does not remember his name. Viren remembers Ashly as the one during the Battle Royal and replies he is Viren, the president of the Rainbow Happy Resort Company. He explains he is here to construct the Viren Tower and shows an image of a golden building. As Viren is boasting, Poipole draws a nasty picture of Viren which Ashly notes it really does look like him, but Viren shouts at them. Ashly and her Pokémon leave and is yelled at Viren never to return as Ashly laughs since Rotom took a video of it and sent it to Anna to show to everyone who got a good laugh out of it.
He enters the construction site shouting at his workers to continue working since his statue will arrive tomorrow. During the night, a giant black object falls near the Pokémon School. The next day, the heroes come to the school and see the giant black object. Ashly and Kiawe believe this is the challenge Kukui has set for them. Lillie, Mallow and Sophocles doubt they could even leap across this thing as Ashly goes to leap, but stops and bashes into the object after nearly stepping over a Diglett. Kiawe runs and jumps at the object (amazing the rest of the class), but the object opens a tile to see Kiawe. Kiawe presses a tile atop the object and falls into it. Kiawe comes out, terrified to have seen many eyes. Kiawe panics, but is hit by Tsareena making the former snap out of his condition and think what the object really is. Suddenly, Komala rings the bell; Kukui tells the heroes about an emergency for the Ultra Guardians.
They come to their base inside the school where Lusamine contacts them about an encounter of a new Ultra Beast. Rotom downloads the data and much to everyone's shock, the giant black object is the Ultra Beast named Stakataka. They come back to Stakataka noting this one does not move at all. To take the very opportunity, Ashly throws a Beast Ball, but Stakataka moves it's tiles making it so the ball misses. Kiawe attempts to do the same with a PokéBase-like throw, but again Stakataka moves it's tiles. The ball hits a tree and returns to Kiawe causing the ball to hit him in the face and making the PokéBase Scyther proclaim a strike. Since Stakataka is dodging the balls, the heroes plan on tiring it out through a battle. Pikachu uses Electroweb which traps Stakataka in it. Next, Snowy uses Powder Snow to freeze a part of it followed with Togedemaru's Zing Zap, Popplio's Bubble Beam, Tsareena's Trop Kick and Marowak's Bonemerang.
After the attacks, Stakataka moves itself as the attacks had no effect. Lillie has another plan: Ashly, Mallow, Lana and Kiawe surround Stakataka and throw the Beast Balls. Stakataka senses this and moves it's tiles causing the Beast Balls to hit the throwers making them fall down. The heroes have not given up yet and continue throwing the Beast Balls. Much to their dismay, they could not catch Stakataka and Lillie reports the failure to Lusamine. The latter notes Stakataka is still calm and decides to observe the Ultra Beast and try again to catch it tomorrow. Kukui believes that to be a good idea and the Ultra Guardians walk away from Stakataka who looks at them. The next day at the construction site, Viren has the statue set up. He reminds the workers should the statue be damaged, they'll have to pay for it. Still, he is thankful that they placed the pedestal in secret, though the workers realizes they were not the ones to have done that.
Ashly runs to school thinking she could catch Stakataka by throwing many Beast Balls at it at the same time. However, Stakataka is gone; Lillie thinks the marks on the ground could be footprints despite none of them having it seen walking. Suddenly, the bell rings as Kukui reports an Ultra Aura in the city. The Ultra Guardians go on their assigned Pokémon riding them to the city. They come to the construction site of the Viren Tower much to Kiawe's anger. As Viren has the statue lowered, the Ultra Guardians enter the site. Viren yells at them to scram though Kiawe shouts there's an Ultra Beast located here. Poipole is interested in the pedestal on which Viren lowers the statue. He lowers the curtain to fully revealing a statue of himself as the heroes are unamused for the statue does not look anything like him. The "pedestal" starts moving revealing it to be Stakataka and it "activates" itself as it's lines and eyes becoming red and stands on four feet.
Viren is worried his statue will be dropped; Kiawe tackles him to the ground avoiding him to be crushed by Stakataka. The rest of the heroes do not see why Stakataka has become angry, but are contacted by Lusamine. Wicke explains that Stakataka hates anything being placed atop itself and will try to remove it. Kiawe notes they have to get the statue toppled down much to Viren's fury. Marowak uses Bonemerang, but to protect the statue, Viren takes the hit of that attack instead. He falls down and it pulled by Lana and Mallow away from Stakataka. Ashly and Storm attempt to go atop Stakataka, but fall down. Just as they are to be crushed by Stakataka, Togedemaru tackles them away. Since it will try to shake anything off, Ashly proposes leaping on it. Kiawe thinks this could work as Stakataka may be a giant vaulting horse. Kiawe sends Turtonator who pushes a part of the wooden wall to use it as a springboard.
Ashly runs at the springboard, but accidentally steps on Turtonator's spike and Turtonator's back explodes burning Ashly and Storm who are thrown onto the statue as Kiawe is glad they made it atop despite this not being an intended way to leap. Storm and Ashly try to push the statue, but notice it is glued to Stakataka making Storm to use Iron Tail and succeeds in pushing the statue off Stakataka. However, the latter is still angry for Ashly and Storm are atop of it still making Ashly to feel something is different as she saw flash backs of that one time period making her to wonder if the song will work as this is not going to be easy to do really. Ashly and Storm wobble on Stakataka and Ashly takes a deep breath before she starts to sing making everyone to swear they saw music notes coming from where Ashly is really.
"All alone on an anxious night
I am humming a song
The darkness that seems to tremble
I can feel the power within it
Every word and every note are
A piece of a miracle
If you hum
Spread your arms wide sharara
That is the melody that rings to the future
From my heart I will sing
I want to send my voice to a faraway place
As of that day hope turns
The phrase is flapping it's wings
Carrying this wish I will sing tomorrow too
As long as my precious person is here
It will be more dazzling than yesterday
I want to meet that smile again
While I was busy I forgot
Irreplaceable things
I had remembered everyone's
Warm kindness
Being too clumsy and not honest
Each time you take a circuitous route
I thought you swore
To the first star
The story that will never change
From my heart let's sing together
Such a wide corner of the world
Even the tears were overflowing
Someday it will shine
Birds tweet and the breeze of spring
Carrying the sounds of the surf even for the sun of summer
While the eyes reflect
Back the love that will forever be told
From my heart I will sing
I want to send my voice to a faraway place
As of that day hope turns
The phrase is flapping it's wings
Carrying this wish I will sing tomorrow too
As long as my precious person is here
It will be more dazzling than yesterday
I want to meet that smile again." Ashly can tell Stakataka is calming down while her friends were shocked at her singing as it seems to changed, but she ask of it to calm down. Surprisingly, it does so and encases itself trapping Viren in it. Viren looks inside and is terrified by hundreds of eyes inside Stakataka looking at him. Lillie believes Ashly has succeeded in riding Stakataka that it now obeys her. Ashly asks Stakataka if she can catch it as she'll be able to return it to it's home world. Stakataka is touched and Ashly throws the Beast Ball and catches it. Viren stands up being wounded by this incident. He is shocked to see his statue has been damaged, but the workers claim now it looks just like him. Viren disagrees and scraps the tower for a PokéBase stadium with his own team.
At school, Lusamine, Burnet and Wicke open the Ultra Wormhole as Ashly sends Stakataka who goes through the Ultra Wormhole and Ashly wishes it good luck. The class compliments Ashly for jumping at Stakataka who promises to do triple layers of what Lana can do to leap and asks for Turtonator's help. By accident, she touches it's spike on the back causing the class to get burnt by the explosion, but they heartily laugh. Later, Ashly walks with Lana to school and much to her and Rotom's shock, they see Stakataka again. Lana passes by stating it is an old rock wall that has been here for some time much to Ashly and Rotom's relief.
