Square Enix announced there will be crossover content between Final Fantasy XIV and Yo-Kai Watch. Thirteen new Yo-Kai inspired weapons (one for each job) will appear in Final Fantasy XIV, as well as Yo-Kai themed minions and a Whisper Mount. The minions will be easy to collect, but the weapons will be a harder get.
For Yo-Kai Watch 3, there will be Final Fantasy themed fusions of Jibanyan called Chocobonyan and Mooglinyan. The game is set for release in Japan in July, which will coincide with the release of the crossover content. While Yo-Kai Watch 3 doesn't have a Western release, fret not Final Fantaseers, the Final Fantasy XIV content will see non-Asian release.
It should be noted that Level 5 studios, makers of the Yo-Kai Watch series, also developed Dragon Quest VIII: Journey of the Cursed King for Square Enix in 2004. Below are images of some of the weapons and the Yo-Kai characters.
