what is Raki's purpose and capabilities?
hmmm... aside from being the reason for living of Clare, I think Raki has a deeper purpose in the series...
maybe he is the legendary knight or something wahahaha! or he may be a half-human, half-yoma already but he doesn't know it yet or manifest it or... he may be an existence that transcends that of humans, yomas, awakened beings and abyssal ones lol!
why? because he has a good smell (as ophelia and priscilla sensed).
why does he smell "good?"
well, i just thought there is a deeper meaning to that smell and i was even to the point of thinking that he is the one that miata smelled in the town lol (if ever she goes wrong with guessing that it's a claymore). XD
