Well, the overarching arc of Pecorine/Eustiana stepping into the light and reclaiming her throne all comes down to this, with a newly-masked Karyl joining Kaiser as her right hand and primary weapon. It’s not clear how much of Karyl’s cooperation is forced, either by magic or deference to Kaiser, but there’s no disputing she’s in a bad way.
When Karyl attacks Diabolos and captures three of their members, Shinobu and Miyako manage to escape and head to the Gourmet Guild to give them the bad news: Karyl has turned her coat. Soon all of Landosol learns this, when Kaiser uses Labyrista’s ability to encircle the city in a shell, then project a giant Karyl who will be the instrument through which Kaiser will sacrifice its citizens.
It’s not just the Gourmet Guild that springs into action to stop Karyl and Kaiser. Doctor Yuni and the Friendship Club collaborate with Kasumi and Tamaki, and the good doctor discovers that the truth that was “out of joint” all this time was the person sitting on the throne: a false princess who has manipulated the minds of everyone in the kingdom.
By the time Yuki, Kokkoro, and Pecorine arrive in town, the place is crawling with Shadows, but adventurers, warriors, mages, and ordinary folk alike manage to hold their own, with the latter even saving Yuuki and Kokkoro when things are looking their most grim. Peco goes on ahead, and from that point on it’s really all about her and Karyl, whose attacks she either dodges or absorbs as she manages to tackle her.
When Yuni uses her “Rosetta Network” of pet rocks to broadcast the truth about the princess currently on the throne, Kaiser orders Karyl to kill everyone—and Karyl is powerful enough to make it happen. But her rain of purple magic bolts ends up hitting no one. As much as she wants to obey her majesty, she just can’t hurt anyone anymore. Kaiser doesn’t take no for an answer, and uses magic threads to manipulate Karyl like a puppet.
Karyls mask falls, she starts to cry and beg someone, anyone to destroy her so she can’t harm anyone else. Instead, her attacks, and Kaiser’s hold on her, are neutralized by a stalwart Pecorine, who finally, finally finds the proper time to tell her dear friend the truth about her true identity. While the duel this week isn’t nearly as badass as the Kaiser-Labyrista bout, it’s a hell of a lot more emotionally charged.
Pecorine does this in front of most of the town, revealing herself to be the real Eustiana von Astrea and vowing to not only save Karyl, but protect her people as well. Considering the power we saw on display from Kaiser last week and all the tricks she has up her sleeve (from Metamorregnant to Labyrista’s power), I’d say the gloves will be coming off next week, which means Pecorine…which means Eustiana will most likely need a little help from her many, many friends.
