Lily is rather nondescript for me. Sure, she is kind of cute, but that's not enough and other than that... well, I've got nothing. Well, I guess the spring thing makes her moe somehow, since many plants start to "bud" there. Which is pretty much a stolen pun, which is awful and shouldn't not be used as reason to vote for her. But then again, I voted for Yuuka, so I probably should just shut up.
I don't care much for Ichirin. But then again, who does? She's just Unzan's hitbox, after all, and massively overshadowed by him. I wouldn't be surprised if she'll get less points than him. I guess, being overshadowed by a cloud (of all things) is kind of moe on it's own (in a "poor little thing" way), but it's not enough.
So, it comes down to the buddhist, who was quite a bitch a long time ago, but got better, and a corpse collector, who is a cat and is BFF with a cute (scientifically proven!) but stupid bird.
Well, Byakuren is actually kind of moe. If I were mean and maybe a bit cynical, I'd say it's mostly because of her naivety (which can be viewed as cute, at least), since she seriously thinks that humans and youkai can coexist. Actually, I say this despite not being mean, so there. Still, "moe" is not exactly something that comes to my mind when I think of Byakuren.
So, it will probably be Rin. She is a catgirl. That alone would be enough to win, since cat traits give quite a nice amount of moe points and the competition is rather weak. However, a few points get subtracted, since she also has human ears (seriously, two pairs of ears? What's up with that?), which also make me fear that the cat ears are actually fake, but since there is no evidence beside her human ears, I won't subtract more points. My impression of Rin has her as catgirl. Obvious, I know, but I think she also has a catgirl personality, at least what I imagine a catgirl to be. I can't really explain it, sorry. In any case, it gives her more moe points. Also, she and Utsuho (who won a a previous round) make good moe buddies.
So yeah, Orin it is. But the human ears are still fucking stupid.
