"...Just ten minutes. I think I'll rest for just ten minutes."
Based on the Shinigami's words, Kaito chose to rest briefly on the black bed. Though he said "rest," he was only sitting down.
The Shinigami noticed changes in his breathing and his movements had become slightly sluggish.
Even in this pseudo-world, Kaito's illness wasn't cured. In fact, it wouldn't be strange if his condition worsened.
According to Mary and Kaito's memories, he had been unable to come here due to the worsening of his illness.
To improve his symptoms even slightly, Mary would need to draw out the magical power accumulated within Kaito. However, this would cause Mary's condition to deteriorate.
While they couldn't show weakness to Kiss and the others in this situation, she would try to help him recover regardless of the circumstances if she saw his condition.
If that led to Mary's death, it would be unforgivable.
If it were just Kaito, he would have pushed himself, but the Shinigami seemed to have taken that into consideration.
"Even if you were to recover with her help, it should be when they're resting too. Isn't there any way to suppress it a little? You managed to last several years without her, didn't you?"
After Mary went missing, Kaito lived for five years. She was supposedly the only one who absorbed his magical power, which is how he had managed to survive. There must be something.
"...There is. But here..."
"I see... poison can also be medicine, huh? Even if it existed in this mansion, obtaining it would be impossible. Using it in front of her would be problematic, too."
What had suppressed Kaito's illness was poison. The new master had been testing experimental drugs on his servants. Kaito seemed to think it might have weakened the magical power while it was in his system.
However, the poison couldn't be completely neutralized, and both the illness and the poison gradually eroded Kaito's body.
The lack of response to the Shinigami's words in Kaito's mind indicated that he had entered a state of rest. This momentary, limited-time rest was probably necessary for a servant.
"Ten minutes have passed. It's fine with me if you rest until the last minute."
The Shinigami had refrained from talking to him until ten minutes had passed, allowing him to focus on recovery.
"...I'm all right. I managed to calm down a bit."
Kaito's breathing was now more composed than before.
"It's unclear if anyone entered during these ten minutes. This is a pseudo-world I created, but I see and hear this world through you. I don't know what happens while you're asleep."
What Kaito didn't see, the Shinigami couldn't see either. The same applied to hearing.
“However, I can sometimes notice things you've seen but haven't noticed. I can sometimes pick up sounds that you've barely heard. Of course, it depends on what you're focusing on."
It was as if Kaito's eyes were zoomed in on something, while the Shinigami's were zoomed out, seeing things from a bird' s-eye view.
Even if two groups were conversing simultaneously, and Kaito was listening to one group, the Shinigami might be able to catch the conversation of the other group that was barely reaching Kaito's ears.
But this was only possible when Kaito was awake. When he was asleep, he was defenseless, and it was impossible for the Shinigami to call out to him or wake him up.
