Omega

''This page is about Omega–Ryuzu Shima's body which is currently being used by Echidna. For other copies from Arc 4, see Ryuzu Meyer (copy) and for the original Ryuzu, see Ryuzu Meyer (original)''

Omega (オメガ) the current Ryuzu copy which contains the soul of the Witch of Greed. Before the fall of then Sanctuary, the clone was known under the name of Shima – one of the original four clones who were tasked with overseeing the Sanctuary itself.

Currently, Omega, accompanied by Colette and Palmyra, is on her way to the City-state of Kararagi.

Appearance
After possessing the body of the Ryuzu Meyer copy Shima and taking the name Omega, Echidna naturally took on the physical form of her host. Omega looked as though she was a petite young girl around ten to twelve years of age. Her beautiful yet pale face was adorned with a long refined nose and almond-shaped cyan eyes,  She wears a large white robe that drags along the ground and is too big for her hands to show completely through the sleeves. As Ryuzu Meyer was a half-elf, Omega's ears were inhumanly pointed. Her long fluffy hair flowed down her back and curved outwards. The only noticeable change Echidna had on the body of Ryuzu was the color of her hair. Ryuzu's hair was naturally rose-colored, however under the influence of Greed, her hair changed to Echidna's white. Befitting a girl her physical age, Omega was rather short, failing to reach even halfway up Subaru's chest.

History
Around 400 years ago, Ryuzu agreed to participate in Echidna's experiments, resulting in the creation of the clones as a part of a project to create eternal life.

10 years before the events of Arc 4, Garfiel ran into the Tomb and challenged the Trials. Out of concern for him, one of the Ryuzu clones–Shima–followed suit and accidentally underwent the first Trial. Seeing this as a good opportunity, Echidna used that occasion to latch a tiny bit of her soul onto her. For the following ten years, she slowly filled the host with her soul, bit by bit.

After the fall of the Sanctuary, Echidna managed to completely transfer her soul into Shima and renamed herself Omega after viewing the memories left in the soul. She then decided to take it slow and first get accustomed to the new body.

She decided to go to Kararagi, her goal remained unknown. While on her journey, Omega met Colette – who had been shunned from her village for being a "witch,” and her friend Palmyra. In actuality, it turned out that she was unconsciously behind the killings as she'd come under the possession of a Meteor that transformed her into a beast. The two girls decided to travel with Omega after the latter failed to straighten things up with the villagers.

They are currently in Gusteko.

Abilities
Pyroxene Crystal (輝石 Kiseki): Omega carries a necklace with her that contains the five souls of the other witches, Minerva, Carmilla, Typhon, Sekhmet and Daphne in it.

Magical Powers: Since Shima's body was not the most suitable host for Echidna to possess, she was forced to leave out her experience with magic. She is still familiar with the usage of magic but is unable to properly cast more advanced spells. According to her estimates, it will take her roughly two years to regain all her skills and powers.

Other Abilities: Omega can project the soul of the Witch of Greed, making it appear as if she's physically standing by Omega's side. By doing so, Echidna starts emitting an intense aura of wickedness and madness which is enough to drive people mad and kill them in thirty seconds. It's mentioned by Echidna that a Sage could endure her aura.

Trivia
