(oh man, seeing Monaco when logged-in is SUCH a relief! But it won't last long XD: )
Noto-sama art IS pretty tough to find, especially since Himaruya has a habit of deleting old stuff. But here's what I can find from the Kitayume wiki for Kitakou:
- Kitakou 2008 banner, Noto in front
- KitaPure banner, 2006 or so?
- KitaPure concept art, 2004
- Another one
- Old 2003-era art
- '04 or '05-era Noto in blue sailor dress
FH14 found a Pure image that might be for the title screen for the abandoned game, but I don't have the link on me right now.
