Rou

was one of the humans fighting in the Holy War 3,000 years ago.

Appearance
Rou looks identical to Ban, except with a neater haircut and a fringe that reaches his right eye. He wears a dark tank top and elbowguards with spotted, light colored pants and sandals. He wears the sheath of his sword on a belt that cuts diagonally across his waist.

3,000 years ago
King and Diane saw Rou when they are fighting against Calmadios. Rou is seen again talking to Meliodas and they become friends, even though Rou knows that Meliodas is a demon.

When the demon army approaches the Fairy King's Forest, he took the task to defend the forest while Meliodas, King/Gloxinia and Diane/Drole decide to go meeting the Ten Commandments and talk to them.

During the stay, Rou interacted with Geharde.

After the goddess Elizabeth had defeated the Indura and Nerobasta informed everyone of the two Commandments' presence, he attacked a giant and a fairy outside the Light of Grace while his comrades dealt with the guards and threatened everyone to stay outside while Gowther and Merasculla were corrupting the gate of light. He said the he wasn't working with the Ten Commandments, only that their goals aligned, to wipe out all the members of Stigma.

Abilities and Equipment
Not much is currently known about Rou, or his skills as a warrior. As a participant in the Holy War that happened 3,000 years ago, it can be heavily assumed that Rou was one of the few humans who were skilled enough to fight alongside the other races, as well as being strong enough to fight against members of the Demon Clan alongside skilled fighters like Meliodas, Gloxinia, and Drole.

Equipment
Shortsword: Rou has been shown using a shortsword in combat, and is quite skilled at using it, being able to injure a fellow stigma member with it without the latter being able to respond to his movements.
