Roe2

Roe2 (also written as Roe₂ or Roe Two) is Shiroe's alternate character (alt) in the world of Log Horizon. She is a female Half-Alv Summoner (with the subclass Vampanella), originally created on a different server (Mare Tranquillitatis).

In the story, her body becomes inhabited by a Traveler entity known as a "Fool" — an artificial being investigating the nature of Theldesia's Empathiom resource — rather than remaining dormant. This makes her an ally to Shiroe (whom she refers to as her "big brother") and an opponent to the more destructive Genius entities.

She appears as a tall woman with glasses, wearing a white coat similar to Shiroe's cloak, and has a striking resemblance to him despite her more curvaceous figure (which earned her playful nicknames like "Ero-ko" from some characters). She is a powerful, level 90 summoner who aids in the larger mysteries of the world after the Catastrophe.
