In the midst of the night:

In the midst of the night the moonlight fell softly down on Tsubaki's face, the window showing the view of the grinning moon.

Black Star was wide awake, he was guarding his weapon by standing in the darkness, as the suns light touched Tsubaki's face he will be off again. Sleeping only an hour before Tsubaki tells him his food is ready.

He wasn't tired. He was Black Star, the man who would surpass god, he doesn't get tired. He will always be the God to protect his Goddess in the long nights to come.
