Ohh, I really like the idea of Snow meeting Yukine after she turns and she helps him with the first steps? And then he could meet any of your other hunters to keep training! I don't know if he should know or not that she's a vampire haha.
Playing out their meeting and the body memory thing would be interesting, I think! We should definitely do that.
And lol, poor Porthos, the only vampire musketeer haha. But yes, awkward friendship ftw.
