Let's see...
Ep
1, 2 - Kusunoki
3, 4 - Chihiro
5, 6 - Jun
7 - Char development (chapter with mom?)
8, 9 - Tsukiyo
10, 11, 12 - Haqua + after story with clay figures
OK the above sounds silly and now I too worry about the pacing.
Either the pacing will be
really fast or they will simply not include all the girls / character development. Both don't sound too nice. >.<
