The history of this model dates back to the origin of the action figure scene. The ""RAcaseal,"" created by sculptor Masaki Apsy, was released at the 2003 summer Wonder Festival as a resin cast kit and gained extreme popularity. Based on this kit, the Phantasy Star Online ""RAcaseal Elenor"" has been created as a plastic model.

This item inherits the concept of an action figure that can be assembled like a garage kit, utilizing a plastic material similar to resin instead of PVC. In addition, the scale has been increased to 1/12 with redesigned articulation. The design has also been refined by Masaki Apsy himself, making for a Masaki Apsy version (Ver. APSY). The color separation has been recreated with different colored parts, and the model's distinctive section ID can be recreated with decals.

Kotobukiya presents this kit as both the origin and starting point for a new line of character plastic models.
