Shin Megami Tensei The Roleplaying Game: Tokyo Conception is the fifth edition of the Shin Megami Tensei TRPG series, based on the 2003 role-playing video game Shin Megami Tensei III: Nocturne. It was originally published in Japan by Jive and released on September 1, 2004, followed by a number of supplementary material. Overseas, the game was published by LionWing digitally in November 2024 and physically on July 15, 2026, following shipment delays that were originally intended to release in April 2025.[3][2] In Japan, the new edition by Hobby Japan was delayed due to needing to reprocess Kazuma Kaneko's artwork,[4] but it was released in June 2026.[1]
A novelization based on a campaign set in the game, Shin Megami Tensei III: Nocturne TRPG Replay Saikai: See You Again Next World, was published in 2005.

| Shin Megami Tensei - The Roleplaying Game: Tokyo Conception is a deep yet accessible TTRPG for 3-5 players + 1 GM that perfectly captures themes of the original Shin Megami Tensei™ video game series, allowing players to wield familiar spells such as Agi and Megido against legendary demons like Jack Frost, Metatron, and the Moirae Sisters.
Tokyo Conception further preserves the franchise's essence by incorporating staple elements such as demon negotiation, the Affinity system, and punishing status ailments like Poison and Stun while also introducing more typical TTRPG mechanics such as critical hits, fumbles, and exploding dice, to ensure encounters are both challenging and rewarding.
Tokyo Conception is based on the world of Shin Megami Tensei III Nocturne™. The game designers have recreated every region with great attention to detail. The book offers nearly 100 pages of stats for every demon, including bosses like Ahriman, Baal Avatar, Noah, and Kagutsuchi itself, and plenty of seeds for brand-new adventures. For video game enthusiasts who enjoy Japanese RPGs and are interested in exploring the world of tabletop roleplaying games, Tokyo Conception is an excellent starting point, as no prior knowledge of the Shin Megami Tensei franchise is needed to enjoy the game. For existing and seasoned TTPRG enthusiasts, Tokyo Conception contains plenty of familiar gameplay features, compelling pre-made scenaios, engaging mechanics, and a deep character advancement system that can be played over days, weeks, months, or longer! |

Overview
In Shin Megami Tensei The Roleplaying Game: Tokyo Conception, players assume the roles of survivors of The Conception, the cataclysmic event that transformed Tokyo into the Vortex World. Playable character types include humans, Demons, and Fiends, the latter being half-human, half-demon beings similar to the Demi-fiend. Player characters are defined by statistics carried over from main Shin Megami Tensei series, including HP, MP, Strength, Magic, Vitality, Agility, Luck, and elemental affinities. The game also introduces tabletop-specific mechanics such as Fate Points, character backgrounds, goals, and contacts, which represent relationships with non-player characters.
The game uses a percentile system based on two ten-sided dice to resolve actions and combat. Its mechanics adapt many gameplay systems from Shin Megami Tensei III: Nocturne, including the Press Turn System, demon negotiation, demon fusion, elemental affinities, Magatama, and status ailments. Characters can recruit and fuse demons to form customized parties, while progression is achieved through improving attributes, learning new skills, acquiring new Magatama, and strengthening demon allies over the course of a campaign. The rules also incorporate tabletop role-playing mechanics such as critical hits, fumbles, and exploding dice. The core rulebook includes nearly 100 pages of demon statistics, including many demons and bosses from Nocturne, as well as scenarios and setting material designed to support campaigns set in the Vortex World.
Following the release of the English edition, LionWing Publishing issued an updated digital version incorporating numerous editorial revisions and rules clarifications. The revised edition corrected typographical and formatting errors, standardized terminology, clarified descriptions for skills, Magatama, elemental resistances, damage calculations, and demon negotiation, and corrected various gameplay statistics, item descriptions, and character sheet errors. Several demon and skill entries were also revised, although the game's core mechanics remained unchanged. Some minor issues, including omitted alignment information for certain demons in the Demonic Compendium, remained unresolved in the updated release.
Supplements
Following the release of Shin Megami Tensei The Roleplaying Game: Tokyo Conception, two official supplements were published that expanded the game's rules and setting. Subsequent Japanese and English editions differed in how these supplements were distributed.
Amala Shinkai
Amala Shinkai is a supplementary rulebook originally published in Japan. Developed as the tabletop counterpart to the Maniax edition of Shin Megami Tensei III: Nocturne, it expands the setting of the Amala Labyrinth and the Amala Network while introducing additional gameplay mechanics. The supplement includes rules for Fiends, advanced spells, expanded demon negotiation mechanics, and additional setting material intended for higher-level campaigns.
The original publication was released as a separate supplement. Hobby Japan later incorporated both the core rulebook and Amala Shinkai into a single revised volume, whereas LionWing Publishing's English localization includes only the original Tokyo Conception core rulebook and does not translate or reprint Amala Shinkai.
The White Vortex
The White Vortex is an official adventure module originally distributed in Japan as a promotional item through a lottery accompanying the first printing of the core rulebook. It contains a complete scenario set in the Vortex World together with encounters, supporting rules, and guidance for Game Masters.
The module was not included in Hobby Japan's revised edition. For the English release, LionWing Publishing translated the module and distributes it as a complimentary digital download to customers who purchase the game directly through its official storefront.
