OFFICIAL DOS DESCRIPTION - Dr. Aiko Tanaka was one of the leading researchers of the Department of Stability in the first few years of its formation. He spearheaded the research conducted at the SKYA facility in Switzerland.

As a former marine biologist and oceanographer, Tanaka noticed several similarities between the metaphysical dimension now known the Reef and coral reefs in real life. He coined the terms the Reef and the Shore for the metaphysical dimension and the human dimension respectively, and was also the first to call the unknown physical matter from the Reef Coral due to its resemblance to coral.
