Yuugi being tall kinda makes sense Komachi it seems fitting, its Yukari and Ran I have a hard time swallowing... and I would think all the faeries would be the same height.
DoubleT said: Medicine is a doll who become a youkai. Not sure how that stands...
Presumably, the artist subscribes to the theory that the "real" Medicine is the little doll we tag as "su-san," and the girl we know as Medicine just appeared when she became a youkai. (Compare Kogasa.)
If I assume the yellow line (600 px high) to be about 5' or 150cm, which seems about reasonable, here's some heights: Reimu: 152 cm Remilia: 118 cm Yuugi: 212 cm (incl. horn) Ran: 202 cm (incl. ears) Shou: 160 cm
