Subaru is the leader of the Scarlet Knights or the Crimson Knights if you prefer, she is close to Crim and Ginkan who are Scarlet Knights, she also becomes close to Tsukasa, whom she became very interested in him as he did not appear as a bad person, just a menness.

She spends a lot of her time within ' The World ' and her character has system powers and can move freely though out the game.... unlike her character in reality, she is a young girl who is in a wheel chair.
Mention she has system powers... she is not an administrator or moderator.

The Key Of Twilight.......she does not belive in this until further involvment with Tsukasa. The Key Of Twilight could change the whole ' The Wrold ' and Subaru goes insearch for it along side Tsukasa.
