A psychic research facility that artificially creates and studies espers. They have conducted experiments for military purposes, bringing in orphans or even resorting to kidnapping.

While they succeeded in birthing espers, many died because their bodies couldn't handle the strain, or they perished from shock due to excessive experimentation. Many researchers also died while trying to stabilize subjects during rampages. Whenever a useful esper finally emerged, they would use their powers to escape the facility and vanish.

Time passed, but the research never stopped.

Then, finally, a subject was created who had no desire to escape and possessed innate psychic abilities. This was Theta. Brought to the facility as an infant, the lab was his entire world. Knowing nothing of the outside, he had no urge to leave.

Researchers attempted to measure and experiment on him, but Theta refused to cooperate. Whether they tried coaxing him or punishing him, there were very few ways to restrain him now that he had gained power.

Lead researchers were constantly replaced, and now, Guest has been assigned as Theta's new lead researcher.
