I couldn’t verify an official Roblox username for the Kalogeras sisters from the available public results, and the posts I found only point to fan discussions and social profiles rather than confirmed Roblox accounts.

What’s publicly visible

  • TikTok and similar fan pages mention “the Kalogeras sisters Roblox username,” but they don’t provide a confirmed account name.
  • Their Instagram presence is public under @_kalogeras.sisters , but that is their Instagram, not Roblox.
  • A fandom-style page confirms the sisters’ names as Sunday, Demitra, and Eliana/Eli, which helps identify who people are talking about, but it does not list Roblox handles.

Safest answer

If you’re asking for their exact Roblox names, I can’t confirm them from reliable public info here. The most accurate answer is: their verified Roblox usernames are not clearly available in the public results I found.

Quick note

A lot of viral posts mix up usernames, fan accounts, and impersonators, so it’s best to treat any “Roblox name” claims as unverified unless the sisters themselves posted it.
