Rilakkuma and Kaoru

Six young people from New York City, on their own and struggling to survive in the real world, find the companionship, comfort and support they get from each other to be the perfect antidote to the pressures of life.

Many years ago, the last remnants of humanity were forced to retreat behind the towering walls of a fortified city to escape the massive, man-eating Titans that roamed the land outside their fortress. Only the heroic members of the Scouting Legion dared to stray beyond the safety of the walls – but even those brave warriors seldom returned alive. Those within the city clung to the illusion of a peaceful existence until the day that dream was shattered, and their slim chance at survival was reduced to one horrifying choice: kill – or be devoured!

Native American siblings Kodi, Summer and Eddy have a secret: They’re "Spirit Rangers" who help protect the national park they call home!

The story is set in the galaxy located near the center of the universe. There are Planet Aernia (a planet for Heroes) and Planet Orbs (a planet for robots), governed by Orbiton, in this same galaxy. Various countries are present in Planet Aernia; they are, Volculm (volcanic country of fire), Zylan (oceanic country of water), Elvan (green-rich country of forest), and Aleum (celestial country of clouds). Antania, is a nucleus of all the present countries. It has an academy that fosters Heroes. Under the reign of the Governor General, Antania upholds a national policy to train Heroes to prevent Planet Aernia to be infringed by the Dark Desire. Heroes are not only the reliable source of battle who have special abilities to freely use the battle discs, but also a symbol of unfailing justice.
