Well, I've got a few moments to kill, so I may as well give this a go...
- Lust = Koishi (due to her subconscious manipulation)
- Gluttony = Suika/Yuugi (due to their massive alcohol intake, and because I hate it when Yuyuko's character becomes little more than a remorseless eating machine)
- Greed = Orin (she likes collecting corpses a little too much)
- Sloth = Komachi (slacker)
- Wrath = Mokou (it's been how many centuries, and she's still mad at Kaguya?)
- Envy = Parsee (it comes with being the anthropomorphic personification of Envy)
- Pride = Remilia (I really think she needs to be knocked down a peg or ten)
if by "subconscious manipulation" you mean phallic danmaku then I guess you just hit jackpot. Can't believe I didn't remember that (maybe because I hate all that bloody fluffy heart storm).
Orin is a good one but I think Reimu and Marisa are still the champions of this one. Same goes for Komachi except in this case it's Yukari.
Again Mokou, yeah, there's that, but Kaguya stole her toy truck, there's no way someone would forgive that. I like Kanako for this cause she is really randomly violent, even more than Marisa ("Hi, my name is Kanako, I'm the wind goddess" "Oh, pleasure to meet you" "Thank you. I pwn you now").
And there's so much more to Yuyuko than JUST eating half the people she meets on her way, that's just the cherry that tops the cake, it doesn't keep her from being the only one that knows that Kaguya and Eirin were the ones behind the fake moon stuff.
