"Omoikane is..." The Nadesico's computer? An AI? Both technically correct answers, but Ruri had been with Omoikane so long he was like a little brother, or her ID. Maybe a bit of both. Still, it would take a very long time to explain.

"Omoikane is my friend. He runs the Nadesico and... Tells me the things I was never taught. I'm kind of terrified what he'll do without me, he doesn't really like humans. They've tried to overwrite him a few times."

"That sounds like 'L'Morte D'Artur.' I think I saw a copy of that once in the director's book case."
