Strahl: Himerareshi Nanatsu no Hikari

Strahl (シュトラール ～秘められし七つの光) is an interactive movie game originally developed by Data East featuring animation by Toei Animation. It was originally intended to be released as a LaserDisc-based arcade game under the title of Chantze's Stone (チャンツェストーン) in 1985, but was shelved. The game would resurface a decade later for the LaserActive's Mega-LD module under the title of Triad Stone (トライアッドストーン) and on the 3DO Interactive Multiplayer and Sega Saturn under its final title.
