JANUARY 29, 2026 – Netmarble, a leading developer and publisher of high-quality games, announced a special collaboration between The Seven Deadly Sins: Grand Cross (7DS) and the hit TV anime series FIRE FORCE. The update includes crossover heroes, the 777 Relay Campaign Phase 2, themed events, and various rewards to players worldwide.

Running from January 29 through February 19, the 7DS × FIRE FORCE collaboration introduces three popular characters from FIRE FORCE into the world of The Seven Deadly Sins: Grand Cross. Three new SSR collaboration heroes join the roster: [Hero of Flames] Shinra Kusakabe, [Red Flame Nekomata] Tamaki Kotatsu, and [Frozen Time] Shō Kusakabe. Shinra Kusakabe, the main protagonist of FIRE FORCE, is designed as a versatile combatant capable of reducing damage taken by allies and allowing to expel one enemy under specific conditions. This position allows him to be a flexible option that can change the tides of battle.

Players can recruit the collaboration heroes through the 7DS × FIRE FORCE Pickup Draw. As part of the ongoing 777 Relay Event benefits, players can obtain FIRE FORCE Equipment Supply Boxes at 60, 150, and 450 mileage on a one-time basis. At 300 mileage, one SSR hero from the lineup is guaranteed, while reaching 600 mileage allows players to select and obtain one of the new collaboration heroes.

A variety of themed events accompany the collaboration, including Check-In Events I and II that grant up to 100 Diamonds over 14 days and up to 30 collaboration Pickup Tickets through three-day login rewards. Special Missions reward growth materials and Holy Relic enhancement items, while Tamaki Kotatsu’s costume will be available as the final mission reward. Additional content includes a Roulette Event featuring collaboration gift boxes and Tamaki’s weapon costume. The Collaboration Event Boss Battle against Shō Kusakabe lets players earn rewards and the collaboration title “Adolla’s Conduit” by clearing the Extreme difficulty for 15 times.

The Seven Deadly Sins: Grand Cross translates the storytelling and adventures of [The Seven Deadly Sins] into a highly engaging and entertaining mobile gaming experience. The game features stunning, high-resolution 3D graphics, more than 100 dramatic cutscenes, and is brought to life with the cast of the original Japanese voice actors reprising their characters.
