He pressed his lips into a hard, white line as Renji quieted down and began. Let it be said that bleeding in front of an agitated vampire was not the safest course of action; though he had no intention of feeding off someone like Abarai Renji, now or ever, the thrum of Renji's heart and the blood on the table served to remind Aidou that his impromptu starvation diet just wasn't cutting it. Not for boosting his healing, nor keeping him healthy. Touching one bandaged forearm, he sat down again, sighing softly.

What, precisely, Renji was doing, Aidou didn't know in the slightest--ever needing to rely on foreign powers, ever having to believe such things even existed, just wasn't something he considered--but it was a great tax on the body, that was for certain.

Searching out 'souls'... Something only Akatsuki would be interested in, no doubt.

He kept his mouth shut all throughout the process, and even when Renji gave him a number, he kept staring at the wall. Staring at the blood wouldn't lead to anything good. Eventually, when he thought Renji's heartbeat might start slowing, he ventured, "Thank you for looking. But are you able to tell where they are?" Three was already the wrong number to Aidou, but revealing his frustration by questioning how effect such an ability was would get him nowhere. Aidou had already made it clear he wasn't human, and any more than that would be too much information.
