Время позднее, так что обойдемся для начала английским копипастом:

"In the near future, Tokyo has been radically redeveloped to become an "enviro-friendly" city, one where nature and man-made structures freely intertwine, and everyone presumably drives water cars and eats gluten-free soy hamburgers. The main energy source in this reborn city is Mystickers, odd sticker-like objects developed by the Next corporation that can summon energy from whatever they're attached to. Mystickers are a part of normal life in Tokyo, and while they're normally harmful if you're silly enough to stick one on your arm, some people (called Blazers) have the ability to do just that -- they can control the Mystickers' power and use them to make themselves super-strong or able to wield magic-like abilities. Blazer crime has naturally become a problem, and a group of good-hearted Blazers called Guardian has been formed to fight them. And now you're about to join the Guardians."
