There wouldn't be any trouble if there were no Zodiarts. What sort of things did Kisaragi normally get into, if Utahoshi was worried like this? Kisaragi was a pain, but Ryusei hadn't noticed anything that warranted this level of concern. Besides, Utahoshi had his briefcase computer.

Even if Utahoshi were to sleep, Ryusei couldn't trust that he wouldn't wake up at any moment. If Ryusei had any sleeping pills on him, this would be easier, but he'd eschewed his mother's offers to get them for him, during the few days of sleepless nights before Ryusei had come to Amanogawa. Not that he knew whether or not dissolving sleeping pills in tea actually worked as intended. It might make Utahoshi's condition worse.

The point was moot; Ryusei didn't have anything that could induce sleep. He had to do something about this using more traditional methods, but if Utahoshi was grabbing a pillow, he probably couldn't be talked into leaving now. "Will you be comfortable there? —Use Miu-sempai's chair, she probably wouldn't mind!"

Unfortunately, the area farthest from the control room was the door. But Ryusei could move Miu's chair around to face the door once Utahoshi fell asleep. He could try it now, in fact— "We can move it so I don't bother you while I work!"
