This is what the mutant beast "Zeal" has reached at the end of evolution, the ultimate overmind. Its gargatuan body, penetrating even the clouds, is but a shell of materialized energy released by Zeal, and its body is inside somewhere near the shell's chest. Sometimes fight, sometimes join hands, the monsters and heroes have developed an intriguing relationship. They are likely to continue to harm the planet. However, the monsters know, that whenever they do so, "those guys will come". Of course, the monsters have no intention to be defeated. With the thought that the time of defeating the heroes has finally come that day, the monsters stand in the way of the heroes for any number of times.
Who are the Cosmic Monsters?
In the broad universe, there are evil beings who attempt to invade and conquer peaceful planets. They pillage and plunder relentlessly for a variety of resources found in those planets, including materials, mana and emotional energies. Some monsters come to Cray as they try to escape from "Dimension Police", while some come to invade the planet. They join hands for their own agenda and fight against the heroes. Their "aesthetic of evil" is "the end justifies the means". Even though they fought alongside the heroes to protect planet Cray from other invaders, their action was nothing more than a result of their "aesthetic". They would fight until they annex the planet, the universe, and everything.
