The Oarburgh clan is a notorious and formidable guild of assassins featured as a major antagonistic faction in the prequel manga Akame ga Kill! Zero. Operating from a hidden stronghold, the clan is hired by the Revolutionary Army to wipe out the Empire's elite assassination units. The group is defined by their immense combat prowess, specialized weaponry, and use of ancient, genetically modified insects known as "Wrigglers". Despite aligning with the rebels, the Oarburgh clan's reputation is highly controversial, largely due to their sadistic methods and the sexual deviancy of their leader. Their actions trigger a deadly, all-out conflict with the Empire's Elite Seven—which includes a young Akame—and the Four Rakshasa Demons, ultimately resulting in the destruction of their guild.

(Leadership)

Merraid Oarburgh, also known as "Madam Mera," is the leader of the clan and the secondary antagonist of the prequel. A highly skilled combatant, she fights using a reinforced umbrella, commands the clan's signature "Wriggler" insects, and can drastically boost her physical stats through a dangerous technique called Metamorphosis. Merraid is exceptionally cruel, misandristic, and predatory; she routinely murders men on sight while systematically kidnapping, assaulting, and brainwashing women to force them into her personal harem. Her disturbing obsession with capturing and "converting" Akame drives much of the conflict between the clan and the Empire.

(Reputation)

Babara Oarburgh, widely feared under the moniker "The Eyes of Oarburgh," is an elderly veteran assassin and one of the clan's most senior members. Having been with the group long before Merraid took over, she acts as a top advisor to the leader and a mentor to the clan's younger disciples. Babara is deeply prideful of her past beauty and her long history of successful hits. She relies on her unassuming appearance as a harmless old woman to drop her targets' guards before striking with ruthless, bloodthirsty efficiency. She eventually dies in battle against Gozuki and the Elite Seven, detonating a bomb in a final, failed attempt to take her enemies down with her.

(Membership)

Taeko and Chelsea serve as two of Babara’s primary disciples. Taeko, known as "The Breath of the Reaper of Oarburgh," is an emotionless and stoic killer raised by the clan since childhood. She wields a sword coated in an incurable Oarburgh poison and is responsible for deceiving and killing Cornelia of the Elite Seven, before eventually being slain in a vengeful duel by Akame. Chelsea, who frequently works alongside Taeko and Babara, utilizes her shape-shifting Teigu, "Gaea Foundation," for infiltration and espionage. Unlike the rest of the clan who perish, Chelsea survives the events of the prequel and eventually becomes a key member of Night Raid in the main Akame ga Kill! series.

(Notable members)

Other notable enforcers include Gilberda and Cassandra, both of whom are deeply devoted to Merraid and dress in traditional maid outfits. Gilberda was sold by her parents as a child due to her innate, terrifying superhuman strength; she can harden her muscles to the point of blocking bullets and fights on par with the inhuman Rakshasa Demons using her bare hands. Cassandra, who was also abandoned by her parents due to being born with four arms, uses her unique anatomy to seamlessly wield four bladed chakrams in combat. Both women fight fiercely to protect the clan's hideout during the Empire's final ambush but are ultimately killed in action.
