The main character has been sucked into the digital world called Pixekai and "your avatar immediately meets a quirky professor and is given a vague mission to explore a large and varied world, taming as many of the 250 different Micromon as you can, and leading them into battle against other tamers for fun and profit". Players are also instructed to defeat 4 Legion Members in order to achieve the title S-ranked tamer. As you explore, a darker grander story starts to unfold, with a Team Rocket-esque evil corporation called Black Root, a mythical Micromon called Vaithe, and eventually a plot to save the world ensue. By the end of the game the bridge between the real and digital worlds is crumbling and only the player can stop it. There are various mini-plots involving the unique towns, including a love story and a game of hide-and-seek with 2 mischievous twins. Touch Arcade notes "thanks to some excellent, colorful graphics, it's still a fun place to explore. Each of the towns has a very different style, and although there are a lot of reused objects, the towns and the houses have a nice lived-in feeling to them". A side-quest involves the player collecting four chip fragments.
