Cassandra, or shorted to Dora was a member of the Oarburgh Clan in Akame ga Kill Zero. She is noted for having a rare condition called polymelia, an extremely rare congenital anomaly characterized by the presence of supernumerary (extra) limbs, which leads to her having four arms. Her parents sold her to a circus where she began her early training with swords.

After Taeko and Babara's deaths, Cassandra (with other members of Oarburgh clan) arrived to eliminate the Elite Seven. Before their ambush on the Elite Seven, Cassandra joined in on Merraid's orgy, and corners Chelsea, who didn't want to participates, but was powerless against Cassandra's holds. Cassandra and Gilbera pursue Poney and Tsukushi, with Tsukushi catching Cassandra's chakrams Cassandra and Gilbera pursue Poney and Tsukushi, with Tsukushi catching Cassandra's chakrams.

On the beginning first battle with Elite Seven Gilberda and Cassandra were fighting with Poney and Tsukushi, girls from Empire fled.

While Merraid was teaching Akame about the true world, they met up with Dora and Gil. Merraid involved Akame into the orgy, kissing her in front of both Gil and Dora. When Akame later distracted the Oarburgh's for Kurome to get the insect cure, Cassandra and the others tried seducing Akame, and it was strongly hinted that Akame was sexually assaulted. Later Cassandra met with Akame and asked her why she didn't seem to be into it when she was kissed by Merraid, Akame was thinking that Cassandra found out about her plan but Dora started saying to Akame that she seemed to prefer recieving love rather than giving it and believed that Akame doesn't want to be loved.

Mez killed Cassandra Mez killed Cassandra During the Elite Seven and Four Rakshasa Demons ambush on Oarburgh's hideout, Cassandra went with Merriad as she fled, eventually choosing to stay behind and delay her pursuers from following her leader any further. She would evntally stop Akame, Suzuka and Ibara as they followed their trail. Cassandra expresses some minor bashful frustration at Akame’s betrayal of their attempt to have her join them, Cassandra then proceeded to engage them in battle, with Akame’s reply to Cassandra that she will ensure all her targets will rest in peace. The battle commences with Cassandra summons some Wrigglers that Mera left behind for her. As the battle intensifies, Cassandra manages to holds her own against Suzuk and Ibara, with Cassandra inflicts several sword strikes that Suzuka couldn't deflects, but Suzuka turns the tide by using her immunity to Wrigglers, having doused herself in the special insecticide that Dr. Stylish created. Causing the Wrigglers to avoid her. While she was busy fighting both Suzuka and Ibarra, Akame gets away and continuous to pursue Merraid.

Leaving Cassandra had to deal with Rakshasa Demons. At some point Gozuki,Sten,Mez and the surviving members of the Elite Seven finally caught up with Ibara and Suzuka,where they thus then joined them in the battle and successfully defeated Cassandra, with Mez seemingly inflicting the final blow on her, thus killing her.
