Aoba had missed many of Kuro's small smiles and gestures. Though when Kuro snapped at him, he playfully poked his nose before continuing on. When Seishu congratulated him, Aoba looked a little guilty. "I kind of. . . I kind of had to say that you would have attacked me if I didn't, um, numb the pain." He poked his fingers together gently after putting the needle up. "It wasn't exactly a lie, but- but I trust you. And I didn't think- or at least I don't think you would attack me. So. . . It wasn't exactly a lie." He knew Kuro didn't much mind a few little minor 'sins', but telling himself such a thing made him feel as though it wasn't all that bad. 

Aoba begins the burning treatment, occasionally glancing over as Kuro would twitch. This was his first time ever doing this, and he didn't want to- well there was a lot of things he didn't want to do- that mainly being, killing Kuro. "This is really bad..." He mumbled in the midst of his work. It made him a little uneasy and nervous, but when Kuro spoke he relaxed a little. There was a sad look in his eye at the knowledge that Kuro might not have made it after his next session but he quickly shook the thought away. He had to focus. The better he healed Kuro, the more likely he would survive. "Um. . ." Aoba thought what he wanted to ask. "Do demons have different forms? I've seen. . . Things like monsters and the likes. At first I thought it was to just scare the younger angels so they wouldn't think about ever going near you guys but," He paused in the burning, mainly to wrinkle his nose at the smell of burning flesh. Gently, he tugged Kuro's hair and shrugged. "You don't look very scary. Well, besides when your angry. But the guards over there look kind of scary when they're angry too." 

In the middle of his work, the fatigue began to settle as well. Not getting much sleep did start to back fire, especially now with him using so much energy to heal Kuro. Aoba turned his head, covering a small yawn, before he once again started to try and fix him. "This smells pretty bad..." He mumbled to Kuro, moving to the last wound. The process lasted longer than his usual ones, so the guards, or at least Green decided to watch skeptically. Red occasionally glanced inwards to check them out.
