This page is about the copies. For the original Ryuzu, see Ryuzu Meyer (original)
Ryuzu Meyer (リューズ・メイエル) is the name of the original Ryuzu Meyer, whom her copies are based on.
Like the original Ryuzu Meyer, all of the copies look the same. Ryuzu is a petite girl with long, fluffy pale red hair that curves outward at the ends. She wears a large white (sometimes black) robe that drags along the ground and is too big for her hands to show completely through the sleeves. The bodies of the copies are revealed to have been created with an artificial "Od" that is surrounded & together with mana, forcing them to change places in order to recharge once they reach their daily limit. Each of the four main Ryuzu take on the role as Ryuzu every four days.
Out of all of the clones, only four (later revealed to be five in the web novel) have an actual personality, as a necessity to perform their duties as main managers of Sanctuary. Although they share the first name with the original they are given different last names as part of their roles, personality quirks, hobbies and interests. The rest of the copies are devoid of any ego and act as simple workers who obey the 4 main Ryuzu or take care of other duties. Those that are recognized to be an Apostle of Greed by Echidna are allowed to gain command over the clones if they touch the crystal the original Ryuzu resides in.
Ryuzu Meyer (original): By her own will, she sacrificed her life to enact the Sanctuary's Barrier by using her own Od which sealed her body in a crystal in order to stop the Warlock of Melancholy from destroying the Sanctuary. She also agreed to be a part of Echidna's experiment as long as the witch promised to maintain the Sanctuary.
- Arma: Ryuzu Arma was in favor of freeing the Sanctuary. She was the one who clarified Subaru various aspect of the conflict within the Sanctuary.
- Bilma: Like Ryuzu Alma, Ryuzu Blima was also in favor of freeing the Sanctuary. She is the 2nd clone Subaru meets and speaks the most with. Bilma also has the most playful disposition among the main overseers.
- Shima: Was against freeing the Sanctuary due to seeing the original Ryuzu's memories 10 years in the trial & had partly been manipulating Garfiel behind the scenes to make sure it didn't happen. She entered the grave in attempt and rescue Garfiel but was forced into taking the trial. In end this meant she broken her contract with Echidna, as punishment Shima was duly stripped from her position as overseer & made live with other mindless clones in the forest, doning the white robe as a result. After the Sanctuary's fall, it is revealed after that incident a decade ago Echidna had been planning to use her to escape once the barrier had been lifted & to that end had slowly been latching more and more of her soul onto Shima, until she successfully hijacked her body. She's currently known as Omega.
- Delma: One of the copies with an actual personality. She was also favor of lifting the barrier. She acted as Shima's support when the later was telling the story of sanctuary's past.
- Others: The other copies don't have knowledge or experience and can only obey broad orders. The copies act as eyes and use their telepathy to relay messages if needed. They need others to order them to eat food once in a while and curl up when they reach their limit in the forest.
- Pico (ピコ): Pico is a copy that Subaru named when he first discovered the original Ryuzu's body. She is able to follow simple orders but other than that she is like a baby.
- Sphinx: The first clone created. Due to the imperfect method of Soul Transference, she could not inherit all of Echidna's memories, personality and power which left her with a fragmented mind.
The Ryuzu copies were created by Echidna in an experiment to research immortality. She copied her memories and knowledge to the copies, however her experiment was never completed because she was killed by Satella. With her gone, the four main copies took over in order to manage the other copies and to take on Ryuzu's role within the Sanctuary when Mathers family supported them.
Telepathy: The Ryuzu copies are able to transmit their thoughts to each other.
- In the Web Novel, main Ryuzu copies did not have already individual names leaving Subaru to give them random greek alphanumeric names instead. There were also 5 main Ryuzu copies instead of 4, those were named Alpha, Beta, Sigma, Theta and Omega by Subaru.
- In the Light Novel, it is revealed that Echidna was slowly hijacking Shima's body, ever since the girl accidentally underwent the first trial, roughly a decade before the events of Arc 4.
