Liko arrives at Indigo Academy and meets her partner Pokémon, Sprigatito.

As Diana prepares to leave the Brave Olivine, Amethio battles Hamber to become stronger.

A battle against the black Rayquaza makes Liko realise all she has accomplished so far!

The explorers cause Liko to become separated from Roy and Dot on Glaseado Mountain.

Liko and Amethio are trapped in a freezing cave and must work together to escape.

Rayquaza is guiding Liko and the others towards Rakua. Meanwhile, Amethio had been going undercover at Exceed in order to look into what Spinel is plotting, but got spotted by security guards and captured. And now a certain person appears...? Amethio learns about the connection between his grandfather Gibeon and Lucius from a 100 years back... and makes a resolve!

As Gibeon attempts to use Zygarde to dig up the Rakulium, Amethio appears before him and tells him... Meanwhile, Liko and the others come rushing over as well, having seen the overflowing energy. But as they attempt to stop the digging, the Rakulium crystal shatters into pieces and a certain someone appears from within...?!

With the Rakulium crystal before them, Liko and the others square off against Gibeon! Liko, Roy, Dot and now also Amethio engage in a fierce seesaw battle against the mighty Zygarde, who is so overwhelmingly powerful it's difficult to even get near it! As the four fight on, they gradually start finding opportunities to close in on Zygarde, but...

Thanks to Pagogo and the Six Heroes, the Rakulium finally gets successfully purified. However, after a brief moment where everyone believes things are at long last over, Spinel suddenly announces he's going to "take control of" Rakua! He then somehow manages to make the Six Heroes go berserk... Liko and the others attempt to escape as Rakua falls to the rampaging Six Heroes. What lies in wait at the end of the adventure to Rakua?!
