A chaotic "Squishy RPG Adventure" gacha game where you'll discover a lot of cute characters, all with squishy cheeks which you can pull on whenever you want. It's parts a visual novel, parts a strategic card-based auto battler where making sure your "Apostles" (the characters that you can recruit) are thoroughly equipped with advantages before and during battles matters a lot. You do that before battles by levelling them up, equipping them with materials, serving them food, and increasing their stats through a "skill tree"-like board. Resources for each of these tasks can be earned through various game modes. During battles, between each round of combat, you're given sets of 3 cards to choose from, each of them with varying costs to a currency that replenishes after each round. While combat occurs, if your Apostle gets equipped with 4 stars through the use of your cards, you'll also be able to activate their senior skill (which will cool down after use for a set amount of time).

You, a human from the real world, suddenly appear in Elias, a world where the incompetent Erpin, queen of the Sprite Kingdom, is in the midst of being overthrown by its upset residents because of a kingdom-wide sugar supply shortage. And the Sprite Kingdom really likes their sugar. As you're one of those so-called "humans" who the prophecies say appears when the world of Elias needs these humans the most, your task is to resolve any conflicts by visiting all kinds of places in the world, talking to all kinds of wacky creatures (like werebeasts, elves and so on) and trying to solve their problems, while Erpin and others tag along and try their best to help out in their own ways too.
