Ok, so I kind of want to try Rise of Mana now, despite the fact that it looks like a cheap mobile knockoff. Evidently as part of a special event with the Vita version of the game in Japan, the original Secret of Mana trio (boy, girl, and sprite) make an appearance, as bosses no less. You'll also have the power to possibly recruit them on your team using the shop.
After July 22, the quest will be gone. Yeah, I need to change my Vita's region again.
