Netmarble released the “Perfect 7” Legend Festival update for The Seven Deadly Sins: Grand Cross on May 21, marking the mobile RPG’s seventh anniversary. The centerpiece of the anniversary update is Nemesis Meliodas, a new hero based on the protagonist’s final confrontation with the Demon King in the original anime. The 777 Relay Campaign, which has been running since January 2026, culminates in this release.
Meliodas mechanics and talents
When his talent is activated, Meliodas channels the power of the 7-person combined technique from the anime’s final battle, entering Assault Mode for one turn to deal explosive burst damage. When his talent is not active, Trillion Revenge takes over, granting him damage reduction and putting him into a counter-stance to sustain him through drawn-out fights.
Theme and naming
The name “Perfect 7” ties directly to the anniversary theme. Seven characters, seven years, and a kit that revolves around that number across both the lore and the mechanical design.
Event buildup and rewards
Netmarble began building toward this anniversary in January 2026 with the 777 Relay Campaign, a seven-month program delivering new heroes and rewards each month. January opened with [Era’s End] Demon King Meliodas alongside 100 Diamonds for all players. March brought [Friendly Classmate] Tree Guardian King, a defensive SSR unit built around countering and taunt mechanics. The full rewards breakdown for the Perfect 7 Festival is available through the official game site.
Milestones and launch context
The Seven Deadly Sins: Grand Cross launched in Korea in August 2019, with a global rollout following in 2020. The game has surpassed 70 million downloads across iOS and Android. Seven years of sustained content delivery is a rare benchmark in the mobile gacha space, and Nemesis Meliodas represents the biggest character drop of the anniversary cycle.
