Shin Megami Tensei – The Roleplaying Game: Tokyo Conception Announced, Releasing Q3 2024


LionWing Publishing has officially announced ‘Shin Megami Tensei – The Roleplaying Game: Tokyo Conception,’ which was previously leaked through an Amazon listing. The book is available though the LionWing store with both physical and PDF editions, with the estimated release window of Q3, 2024.

Based on the very iconic, world-renowned video game series, this TTRPG is perfect for 3-5 players + 1 GM (Game Master) and is page-packed with familiar spells, characters, demons, and revolves around the iconic Vortex World. The book was designed and written by famed Japanese TTRPG author Yusuke Tokita, who has decades of experience in tabletop game design and has honed his craft to develop a unique design style over the years. Along with Tokita, the designers of this book have recreated every region from the game in amazing detail, and the book contains nearly 100 pages of stats for every demon, including bosses like Ahriman, Baal Avatar, Noah, and even Kagutsuchi!



Shin Megami Tensei – The Roleplaying Game: Tokyo Conception is a deep yet accessible TTRPG for 3-5 players + 1 GM  (Game Master) 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.


  • EXQUISITE WORLD DETAIL – 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.

  • A BOOK SUITABLE FOR ALL SKILL LEVELS – 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 scenarios, engaging mechanics, and a deep character advancement system that can be played over days, weeks, months, or longer!

  • CLASSES AND PROGRESSION – In Tokyo Conception, players start out by choosing one of three character classes: Human, Fiend, or Demon, with each class possessing its own unique strengths and weaknesses.

  • FACTION DYNAMICS – While a lot of Tokyo Conception deals with fighting demons, it definitely doesn’t stop there. Kagutsuchi still burns brightly in the middle of the Vortex World, and it awaits to judge those who would offer their Reason as the basis for the new world. Will players support one of the three existing factions? Help the manikins develop their own Reason? Or will they use the robust faction rules to establish their very own? The choice is theirs… if they have the will.

  • DEMON NEGOTIATION – Similar to the video game series, players must carefully navigate Tokyo Conception’s Talk Flowchart and use an array of talk skills to engage in conversation and negotiate with demons to earn items, gems, or even acquire their Demon Cards. Make a wrong move, though, and the demon may attack or even flee entirely!
