Perhaps it was more a matter of when than if, Dragalia Lost has announced a collaboration with Princess Connect Re: Dive for late November! A Voracious Visitor will feature Pecorine as part of the event story, as well as a summonable Adventurer. The official news post notes that Pecorine will be the only Priconne character who will be appearing in this event despite the Karyl and Kokkoro cameos in her art, and she is NOT a limited character!
A Voracious Visitor is a raid event in which Pecorine will get to know and cooperate with adventurers from the world of Dragalia Lost in an original story. Two adventurers from the world of Dragalia Lost will appear in the event story as you’ve never seen them before, alongside a brand-new dragon! One of these adventurers will join your roster if you manage to befriend them during the event, and the other can be summoned in a showcase. The dragon will also be available in a summon showcase.
Presumably these characters and dragon will not be limited as well, but specifics were not given. Additionally, to celebrate Princess Connect being canon in Dragalia Lost, players who start playing before 13 December 2020 21:59 PT can get a bonus gift of 1,200 wyrmite! The preview video for the event, featuring MAO singing the event’s theme song, can be viewed below:
