Altair

Unlike the other Created, who are incognizant about the fact that both themselves, their experiences, and the worlds that they dwell in are considered to be fictional, much less know anything about their Creators, Altair is not nescient about such information. Rather she is completely au fait about her own existence, about the real world, as well as her creator, Setsuna Shimazaki, who Altair had strong love towards. When Setsuna's suicide occurred, Altair shows great hatred towards the world.
