Basic plot...
In Japan, ten year ago, Mushi appeared, no one know where they came from, nor what exactly they are, but they look like bug/insect, and latch on to a person and feed on that person's dream. Some people says it's a reward other say it's a prank, but people that got a mushi, gain ability through their bug.
To combat this threat, and to keep the information of Mushi a secret, the japanese government formed a special environment protection agency to keep it a secret, and study the phenomon.
The people that got Mushi, when the Mushi finish eating a person's dream, the host die, and the bug become a grown mushi, gaining unparalleled power and durability.
When a Mushi get destroyed, the host lose all their ability to think and emotion, following only orders.
