Netmarble has launched a new update for The Seven Deadly Sins: Idle Adventure, as they have added the Demon King's Deputy Zeldris to the roster. There isn't much to this update compared to others.

Fans will know the boy’s name is Zeldris, and he is a rather important character in the franchise. The boy is an elite warrior from the Demon Clan, and he is one of Meliodas’ younger brothers.
