The Skills Development Laboratory is a facility operated by Haijima Industries. The facility is primarily used to examine the skills of children with Ignition Abilities to teach them to control their dangerous powers. Some children stay for many years until they move into the outside world. According to Shinra, the scientists view the child as tools and the building was devoid of warmth. However, the laboratory currently allows children to experience modern entertainment through books, toys and puppet shows. In spite of this more relaxed appearance, the staff have recently intensified the research into the Adolla Burst, pushing their child subjects into experiencing permanent injuries or death in order to understand the Adolla Burst. As a result, the researchers hide the presence of Nataku within the facility while putting him through rigorous combat trials with Kurono.
