Oh, yeah. I mean, I've read that too but before that the resemblance to an actual physical wolf is, for me, uncanny. Like, if this became a supernatural manga and just the middle brother was a werewolf I would not be surprised.
That would actually be pretty interesting to read. But he does give off a were-wolf like vibe. His younger brother would be like a bunny or something, that'd be cute.
The middle brother reminds me so much of a wolf. I look at him and all I can see is lead wolf protecting the pack.
