ミコト

Mikoto is an artificially created human based on Iceman's body. Iceman names her based on her identification number 3510. The word Mikoto can also be written as 命, which can also be pronounced as 'inochi', meaning 'life'.

She was given a master key to the research facility by Mizushima so that she and Iceman could escape. She gave birth to Iceman's child, but was recaptured and butchered by scientists for research. The master key was passed down through her descendants and eventually became Eruruu's hair ornament.
