[You learned the passive Sleep Resistance.]
Sigma wanted to sigh, but he was too tired for that. He also felt that he wasn't in a good mental state since he was starting to think that it wouldn't matter if he fell asleep, and Shyona ended up cutting his throat.
Speaking of which, during those three days, Sigma noticed that she hadn't eaten much, but she kept staring at the pile of blood that he left behind when he got hurt. She really liked blood, but she didn't want to drink from the ground, and she could contain her urges in her human form.
Eventually, Sigma fell into temptation and then fell asleep on the fourth night. He had recovered a bit of his blood, and he didn't feel that physically weak anymore… the problem was his mind, and he solved that when he slept. When he woke up, he saw Shyona close by, staring at him… he could tell that she argued with herself for many hours and wondered if she should kill him in his sleep or not to get his blood.
