"As for the "Power", it's inside you. Now, draw it out."
- —Rem's quote, Tokyo Xanadu
Rem (レム Rem?) is a sub character in Tokyo Xanadu. Rem is from a race known as Greed and is a mysterious being who speaks in a boyish tone and calmly wanders the Other World. Often referred as a female, she is well-regulated with androgynous features, but her actual nationality, gender, and age are unknown. It is not even known if Rem is human.
Often known as the "Child of Eclipse" because of her connection to it. Rem is sometimes thought to be an enemy and friend. However her sole intentions are only to test the X.R.C.'s abilities against the Eclipse.
One day, she stumbles outside of the Other World and suddenly appears before Kou. As one eligible for it, she gives Kou the chance to manifest his Soul Device.While she can often be seen appearing around Kou for assistance, at times she only appears to observe Kou’s actions as a bystander, so her true intentions are not clear. She gives Kou the chance to manifest his Soul Device and seems to have knowledge about something called “Xanadu".
She has a glowing, transparent-like body, and thus appears to be a being between that of the real and Other worlds.
Rem is known by the Underground as the "Child of Eclipse" for her connections to the "Eclipse". She may sometimes be devious against the X.R.C but she only wanted to try their abilities. She is also close to Kou's grandfather, Sousuke Kokonoe, who have also knew her from the Tokyo Disaster.
