While the Brave Asagi is being repaired, Liko, Roy and Dot have gone to the Orange Academy in order to learn about the Terastal phenomenon. While there, they meet Director Clavell, as well as Top Champion Omodaka and the Paldean Elite Four and learn about their coming trials to learn how to Terastallize while participating in the Orange Academy's school life. How will their first day go?

Liko, Roy and Dot have gone to visit Kaede, the Gym Leader of Cercle Town, for Liko's Terastal training assessment test. They make it to her shop "Patisserie Mukuroji" without any issues, but then Sango from the Explorers barges in and the situation somehow turns into a confectionery cooking competition......?! How will Liko and Nyarote's Terastal training go?

Roy's opponent for his Terastal training assessment test is Colza! Roy is eager to battle him, but Colza has to postpone the training due to being busy preparing the art festival that's going to be held in Bowl Town. Just then, Nemo happens to pass by and asks Roy for a battle, which he agrees to. But when Colza watches their battle, it seems he has some thoughts about Roy's battle style...?

Now that Liko and Roy have taken their assessment test, the last one in line is Dot, whose tester Gym Leader Nanjamo tells her the assessment test will be streamed live on Donnamonja TV. Dot battles Roy as a rehearsal for the stream, but is so nervous about the cameras she's unable to work well with Kuwassu...?!

Dot and Kuwassu are finally going to take Nanjamo's assessment test! They had researched Nanjamo's battles in advance, developed a strategy and taken infallible countermeasures... or so they thought, but they still end up struggling greatly against Harabarie, who's a poor type matchup for Kuwassu. In addition, an unexpected incident takes place...? Will Dot be able to pass the test?!

Liko, Roy and Dot are observing and gathering information on wild Pokémon in order to find a subject to write a report on. Dot tells Liko about a mysterious phenomenon called the "Flower Pillar" that will reportedly bring happiness to those who see it, and Liko decides to search for it with Nyarote to write a report on it. But for some reason, Nyarote is currently in a rather bad mood...?!

As Liko, Roy and Dot continue observing wild Pokémon for their report, Kaiden gets frustrated with its inability to fly properly in strong wind to the point of getting into a fight with Hogator. That night, it secretly sneaks out of the tent to practice flying by itself, but when Roy and Hogator notices it's gone, they go searching for it. However, unnoticed by them all, a shadow draws near...

Liko, Roy and Dot go into a forest to search for something called "the unworldly" that a mysterious person told Roy about. As they cautiously head through the forest, they meet three people that look just like them?! Apparently these three Trainers have also encountered "the unworldly"... But just what IS "the unworldly"?
