Muramo「ムラモ」 is a New Generation Holy Knight and he was the first victim to be forcibly transformed into a Demon mutant by Hendrickson.
Muramo wears a set of full-body armor with a helmet exposing his face. He has brown hair and black eyes that were the result of drinking the Demon blood and survived.
Muramo is a very serious and hot headed man, as he was quickly draw to anger and willingly to fight Hendrickson, despite not knowing who he was or what he was capable of.
Muramo along Parada, encounter Hendrickson who easily destroyed the Liones Castle, nearly killing all Holy Knights and the Seven Deadly Sins inside and Muramo is ready to fight him. However, his partner calms him down and try to speak with Hendrickson until the latter uses Blood Awaken which awaken the demon blood that transforms the New Generation Knights into hybrid Demons, including Muramo, who eats his partner.
Later Muramo climbs to the top of the ruined tower and attempts to attack the Sins and the Holy Knights but is pushed back by Guila's Explosion. When Ban and King begin to root out every single demon plant within the New Generation throughout the capital, Muramo was presumed to have been reverted back to normal and lost his powers.
As a Holy Knight, Muramo's combat capabilities must be far above the level of an average human. However, due to the demon blood he drank and survived the ingestion, it is possible that Muramo is much stronger than a lower-ranked Holy Knight.
After being reverted back to normal, Muramo lost all of his powers.
Muramo possesses a double-edged sword that he uses in battle.
- His name and appearance is based on Daisuke Muramoto from Woman Rush Hour comedy duo.
