Has it been a week yet? Arranged in a sort of ranking system this time because, oh, I don't know, just because. D:
People who know about The Minotaur (this means you're special)
Killua (understands Kuro's neurosis' on a personal level) - Understands Kuro as a whole better than anyone else in Adstring, maybe even as much as Shirou back home. Killua came just to sit with Kuro when he was fighting The Minotaur, realizing that, more than words, Kuro simply needed someone near to keep an eye on him. Despite entirely different backgrounds, the similarities between these two are simply too many to count, and friendship was pretty much instantaneous; Kuro really enjoys their versions of tag, and might admit to Killua being better than him, if caught in the right mood.
Beyond (promised not to leave) - The first person that Kuro told about The Minotaur, Beyond gets big points in Kuro's mind because he promised not to leave and, whether he'll ever admit to it or not, Kuro is a deeply dependent person. Kuro doesn't care one way or another about Beyond's murderous background, probably because he figures he has no place to speak in that regard. He also gets points for sharing his jam with Kuro, because living on the streets, anyone who offers you free food is pretty much a friend for life.
Tolerated (this means he kinda likes you)
Ginia (didn't tell him NOT to eat the squid) - One of the least annoying girls Kuro's spoken too thus far, Ginia didn't whine about the squid's rights to him, hasn't tried to push him to do anything he doesn't want to or judged him in any way. She's just sort of... there, and it's almost relaxing talking to her. Plus, he's seen her fight, and any girl who can wield a machete like that is okay in his book.
Need to be protected (so does this)
Ciel (doesn't like the sound of this "asthma" thing) - Is mostly just terribly concerned about the asthma, which he'd never heard of before. Ciel is stubborn, but Kuro is even more so, and he's got an intense soft spot for young children who obviously can't take care of themselves. He'll continue to keep a close eye on this kid.
Salad Fingers (lol, shut up, I know; he reminds Kuro of the stranger side of Shirou?) - Undeniably a strange person, but Kuro really can't be one to judge people in that way, and he's interesting to look at in any case. Talks weird, but then, so did Shirou, and he doesn't seem to be any good at taking care of himself, so Kuro worries.
