Two demons, called Megami Izanami and Fiend Tokisada, were scrapped from the game. Both had artwork created for them by series demon artist, Kazuma Kaneko, but went it ultimately went unused.

Tokisada would eventually appear in Shin Megami Tensei: IMAGINE and Shin Megami Tensei IV as both a boss and an ally. Izanami also appeared in Shin Megami Tensei IV and plays a large role in Persona 4, albeit with a differing design.

In a change from the normal Character Designer of the Megami Tensei series, the character design for NINE was handled by Yasuomi Umetsu, most well known for the creation of the violent hentai anime titles Mezzo Forte and Kite.
