The land is currently in the middle of a harvest festival that the group end up taking part in, where Friede takes great interest in the Yabasocha belonging to Seille, a girl he meets there. Meanwhile, Roy and Achigator accidentally touch a machine set up at a stall, which causes them to switch bodies...?!

After hearing that Briar is at Terasu Pool, Liko and the others start climbing Oni Mountain. On the way, Kanuchan is overjoyed to spot some nice iron, and starts pounding it with its hammer. Dot is overwhelmed with emotions from seeing Kanuchan's hammer grow in size so suddenly... but then a wild Otoshidori shows up and takes Kanuchan's iron.

As Liko and the others reach Terasu Pool, they locate Briar, who becomes extremely excited when she sees the Terapagos Liko has with her!! When they ask Briar about Terapagos, she takes out the Scarlet Book and starts explaining to them how it concerns the adventures of her ancestor Heather in Area Zero of the Great Crater of Paldea...

The details surrounding an unknown adventure that took place a hundred years ago will now transcend vast time and finally be revealed!!

Friede suggests Liko and the others meet with someone named Sohdayo who can help them locate Entei. When they land on the savannah, they're immediately attacked by Rikikirin... but just then, Sohdayo suddenly shows up. He introduces himself as a "truthful Pokémon journalist"... and is actually a former member of the Rising Volt Tacklers?!

While visiting Randou's hometown Asagi City, Liko and the others meet the fishing boat rental operator Mamoru, a passionate fan of Kinjiro, a movie star of yesteryear. Mamoru tells them about his enthusiasm for the "VS Samehader" movie series Kinjiro starred in.

An eyewitness report has led the Rising Volt Tacklers to conclude that Entei, which is highly related to volcanic activity, is likely to appear near an undersea volcano, and take turns lying in wait for it there. And then one night, Entei appears with a loud roar, challenging Liko and the others to a battle in order to test them!

Liko and the others return to the Paldea region in search for more information on Entei, and go see Pokémon League chairwoman Omodaka to get permission to enter Area Zero of the Great Crater of Paldea.

Liko and the others finally locate Entei in Area Zero! However, this Entei seems kind of different from normal Entei. Liko, Roy and Dot challenge it to a battle, getting help from Friede as well, but moves that should be effective against a Fire type like Entei aren't having much effect either?! But why...? And will Liko and the others manage to overcome Entei?

The Black Rayquaza once again appears before Liko, Roy and the others, and they all challenge it to a battle together in order to gain its approval! However, despite incorporating the terrain to great effect in their combo attacks, they gradually end up driven against the wall by the overwhelmingly powerful Rayquaza! Liko's wishes... Roy's desire... What's going to happen to them at the end of this fierce battle against the last member of the Six Heroes?!

Rayquaza guides Liko and the others to a mountain towering high into the heavens.

As the group soon learns, local legend has it that disaster will strike when the Black Rayquaza appears.

Liko and the others finally arrive in Rakua, which was located at the peak of Mt. Kumli. Here, a virtual paradise spreads out before them, with rich and plentiful nature and many wild Pokémon living in peace and quiet! Deeply moved by this sight, they start searching for 100 year old traces of Lucius. But a certain Pokémon is keeping an eye on them...

In the center of Rakua, Pagogo releases the barrier it set up a 100 years ago... but then the Explorers suddenly appear, having been lying in wait for the barrier to get released so they can obtain the Rakulium...! The decisive battle in Rakua over the Rakulium now begins: Friede VS Spinel, Liko VS Onyx, Roy VS Sango and Dot VS Agate!!

It has been one year since the decisive battle in Rakua. One day Roy, who has continued adventuring with Captain Pikachu, learns about a Pokémon that's acting abnormally, and decides to investigate. A young boy named Uruto then appears, accompanied by a Yamirami... In the forest, Roy and Uruto spot a Kekking on a Rakulium-induced rampage?! How can this be, when the Rakulium was supposedly completely destroyed? Liko, on the other hand, is attending Sekiei Academy, when she suddenly...

Liko and Roy once again set out on a journey, this time in order to restore the truth about the Rising Volt Tacklers. Using information they receive from Dot, they chase down a Pokémon affected by Rakulium. This leads them to a place with countless holes in the ground, as well as traces of Rakulium...! Suddenly, a savage Haganeil shows up! How will Liko and Roy take on this Pokémon that boasts an impregnable defense?!

Gurumin receives an eyewitness report regarding the Black Rayquaza! Liko and Roy go to the town where the eyewitness lives, where they find the passionate Gurumin fan "Nyabby Girl".

A battle starts, and Nyabby Girl sends out a Gaogaen, which Masquernya is at a type disadvantage against... What will Liko do?!

When Liko and the others learn that more and more Pokémon in a forest are getting sick, they begin to investigate whether or not this is because the Pokémon are affected by Rakulium. In the process, they run into Molly, who's treating poisoned wild Pokémon! Molly is currently working at a Pokémon Center... but the happy reunion gets interrupted by cries from scared Pokémon coming from the depths of the forest....! As they continue further in, they find a berserk Ruffresia scattering poison in all directions...?!
