Crow's fun! Cat adventures, candy adventures, he's cool with impulsive activities which is great because Yuuki is also down for those types of things. He's laid back but still gives off a reasonably reliable vibe, so she trusts him well enough on whatever shenanigans they happen to be getting into that day. The fact that he backed her up against the wendigo added to that immensely, thank u for looking out for her.

Also her brother is perfectly fine... probably... don't worry about it.
