Kamui: He keeps having bad dreams so he doesn't rest well. He probably sleeps around five, six hours, and about 3 days at least it's of interupted sleep. He sleeps on his side when he's not hurt, in a fetal position.
Gigei: Sleeps hugging Ashura when Ashura sleeps with her. If not, she sleeps on her side, an arm behind her head. She sleeps about seven hours and she wakes up early in the morning. She has a light sleep, though.
Eagle: SLEEPS LIKE THE DEAD, NOTHING WAKES HIM UP WHEN HE SLEEPS. At least eight hours a day but he could still sleep easily twelve, but he's not giving himself that chance. He's still not quite recovered from almost-dying, but being the pushover he is, he'd rather act normally instead of making others worry. Usually sleeps on his back, but if he's sleeping with someone else he loevs cuddles.
Yuuko: Although she is very lazy she doesn't sleep that much. Usually sleeps face down so that she can pull the covers over her head. She has lousy bed-sharing manners, too. She steals the covers AND she'll move all over the bed.
