Ruvii Redcore

Her YouTube channel was created on 24 March 2026, and her Twitter account was created in March 2026.

She debuted on 8 May 2026 at 5:45PM PST on YouTube.

• Ruvii is one of 7 clones created by the organisation Ares Eterna, the purpose of the redcore program is unknown but is implied to have something to do with the ruined world in which Ares Eterna resides.
• In the lore video Ruvii is sent on a mission to an unknown source and is esekai'd into the world that includes her genmates, This then quickly breaks the conditioning enacted on her by Ares Eterna. One explanation for this is that Ares Eterna clearly has access to other universes so in order to find capable candidates for the program they acquire them from said universes. Hence if one is returned to your universe of origin it would be possible to break conditioning.
