Yes, the modern-day Yamaguchirow story is the one with Kaoru on the phone-- I couldn't remember the title, since all of that information is in kanji :b (I wonder if I have any chance of working out their modern-day names, other than the same "ken" and "kaoru" kanji still being there...)

"Sakuragari" is mostly a sketchbook. It has lots of modern-day stuff-- some of them look like early ideas for "Kuusou", though that doesn't explain Enishi dressed like a teacher(?) or Tomoe as a waitress-- plus a bit of Yahiko/Tsubame and several pages of Aoshi working his way through all of the girls of the Oniwabanshuu.

Looks like euphoricvisions is reorganizing its site-- I'll have to register and take a look around when they get their login system working again.
