Sloth - Could easily be Yukari, or Mokou. Greed - Megumu probably fits this best. Gluttony - Yuuma, if you're taking it seriously. Lust - Koishi, in terms of pure hedonism. Could also make the case that Tenshi fits this better, causing chaos just to feel something (in which case, Zanmu or Okina could take over pride)
