Index Digital Media Inc.

The corporate branding emerged following Index Corporation's acquisition of Atlus in 2006, restructuring the localization and distribution pipeline for niche Japanese intellectual properties in Western markets. Within the Shin Megami Tensei franchise, this period was marked by a concerted effort to bring classic handheld titles to English-speaking audiences, preserving the dark, tactical gameplay of the series.

For the King of Fighters series, the publication of King of Fighters XII marked a pivotal transition to high-definition, hand-drawn sprites, requiring extensive distribution coordination for its console releases. Additionally, the publisher facilitated the Western arrival of Vanillaware's highly stylized action role-playing game Dragon's Crown, further cementing the company's association with artistic Japanese imports.

This operational era concluded following the financial restructuring of the parent company in 2013, when Sega acquired the assets. Subsequent releases in these franchises reverted to the traditional Atlus brand, leaving this specific corporate moniker as a distinct marker of a transitional period in late 2000s and early 2010s gaming history.
