According to Square Enix, the Japanese developer has teamed up with LEVEL-5 to bring Yo-kai Watch characters and gear to Final Fantasy XIV this summer. The characters and weapons, seen in the images below, will be seen and earned as part of special quest rewards.
Square Enix/LEVEL-5 have also mentioned that this won’t be the only Yo-kai Watch and Final Fantasy crossover. In the latest Japanese Yo-kai game, Yo-kai Watch 3: Sushi and Tempura, players can happen upon two new Yo-kai: Chocobonyan and Mooglenyan (based off of the iconic Final Fantasy chocobos and moogles, respectively).
Final Fantasy XIV is available on PC, PlayStation 3, and PlayStation 4; Yo-kai Watch 3: Sushi and Tempura versions come exclusively to Nintendo 3DS on July 16, 2016 in Japan.
