Roe2

"I understand perfectly! The black stuff being poured here is a sauce, then does that mean the black stuff being poured is soy sauce?"

- Roe2, Volume 8

Roe2 is Shiroe's alternate character avatar, a Half-Alv Summoner-Vampanella. Although she was originally on Mare Tranquillitatis, her body ends up being used by a Fool who is intent on finding out who was rightfully in possession of Theldesia's Empathiom, whereas the Genius are simply intent on harvesting it by killing Landers and Adventurers alike. As a result, Roe2 primarily opposes the Genius and aids her "big brother's" (Shiroe's) cause.

Appearance
Roe2 has the appearance of a tall woman dressed in a white coat wearing glasses, with rather voluptuous curves. Notably, she dons the same cloak as Shiroe and bears a striking resemblance to him. In spite of that, few people have figured out that she was actually Shiroe's alt.

Personality
Roe2 is naive about Adventurer-created items such as food, and is rather curious about them, considering that the mind in control of the body is a Traveler, who normally are ephemeral. She takes a liking to being called "big sis" by Tohya and Minori, and complains that her "big brother" (probably meaning Shiroe) gave her an inconvenient subclass. However, despite taking a liking to Tohya's Party, she finds human societies illogical and claims that they have an inefficient social structure.

Gold of the Kunie arc
After the Abyssal Shaft Raid Party wipes out, Roe2 appears near Seventh Fall, rising out of the snow and staring at the moon. On Mare Tranquillitatis, Shiroe notes that he had created an alt, meaning Roe2, on the test server.

Route 43 arc
Tohya's Party, while traveling in the Sakawa Region, encounters a group of People of the Land facing against a horde of Ogres when they first hear a voice through the trees warning them of more higher level ogres being on the way. As the Group is fighting the monsters, Roe2 appears out of the forest to join them in battle and summons a Princess Wraith to aid them in battle. She also formally introduces herself to the group and reveals that she is a vampire as shown collapsing under the heat of the sun who is also traveling to the south in order to change her subclass, complaining that the person who chose it for her gave her a rather cumbersome one.

She mentions that she was on the moon, having switched with somebody approximately three months before the group met her and landing in Oou (the location of the Goblin King). After staying with the group in the town of Yuyugi, she volunteers to help them as long as they treat her like an older sister.

When hundreds of Wyverns invade, she watches with Tohya and Minori as the Odyssea Knights charge at them, recklessly killing and being killed, even by their own men. They would revive soon after at their portable shrine and simply return to battle, prompting Roe2 to comment that they seem to be addicted to death. She continues on to say that she finds human social structures illogical and inefficient. At this, Minori, who has been curious about her existence, asks who she really is.

She explains who she is, but engages in much jargon that extends beyond both Minori's and the reader's understanding. Then, she participates in the battle, determining to assist her first friends in their attempt to save the town. After the battle, she departs after handing Minori a letter and requesting something from her.

Homesteading the Noosphere arc
The volume begins with Roe2's letter, addressed to Shiroe, which was written while Tohya's Party was in Sapphir. The preface explains that she is a Traveler, a race of mental bodies that were brought to the world of Theldesia because of the Catastrophe, which they called the Eclipse (its kanji means "pact"). She continues to explain that her race is split into two factions: Fools and Genius, although she does not explain why at the moment, but states that this was the reason why she couldn't properly explain things to Minori. While the Travelers had an explanation for the Catastrophe, it wasn't a solid principle and they had no solutions as to how to return to their own world.

After splitting from Tohya's Party, Roe2 heads for Jaxea, which is Elder Tale's equivalent of the JAXA Space Station. Around the time the Shibuya Raid Team defeated Tacritan, Roe2 single-handedly protected a rocket ship at Jaxea from the swarms of monsters, then wondering aloud if she had helped Shiroe and her "little siblings".

Manga
Although she isn't seen, when Shiroe first logs on after downloading the Homesteading the Noosphere expansion pack, her name, level, class, and location are seen in one panel. However, unlike the novel, she is stated to be on the North American server. (The English fan translation also mislabels her as a 'Half-Elf'.)

Trivia

 * Being Shiroe's former alt avatar, Roe2 speaks with a masculine tone (but still a feminine voice).
