Guessing that the pink hair is Mokou, the brown is Byakuren, and the leaf may be Momiji or Aya. For the first two, see post #1173639 and post #1178045. The latter is just a guess, given Aya's previous appearances and Momiji's association with the maple leaf.

If nobody else tags them by the time I get back, then I'll be sure to do so. But, the hair bow is indeed Mokou and the maple leaf is Aya. I don't recall Mattari having debuted Momiji in the series.

Uh I would have thought Kanako would be a better choice than Aya, being a direct friend (Or close to one.) But hey maybe he just wanted it to be aya, Still curious where this goes

You know, now that you mention it... it would make more sense to tag Kanako, since she's wearing the leaf in her hair throughout the series.
