The female VTuber was likely Arielle-VT , based on the recent Meccha Chameleon VTuber stream lineup and clip references that include her among the participants.

Why this is the best match

  • The most relevant recent Meccha Chameleon VTuber video I found lists Arielle-VT alongside several other VTubers.
  • Another related Meccha Chameleon VTuber stream is also from the same recent cluster of uploads, which makes this the strongest context match for your “juked everyone on a Minecraft map” description.

Confidence

  • Moderate , not absolute: the search results confirm the event and cast, but not the exact clip moment you described.

Quick note

If you mean a specific clip or meme going around forums, the answer could depend on which stream moment people were reacting to, but Arielle-VT is the most likely name from the available public references.
