Indeed! This is a good use of the artbooks.
It doesn't include like an R18(genitalia'd/nippled) version of the arts existing in-game, but any other illustration not included in the game had them, as well as little notes.

Then a particular cameo art has just their names on it w/o explanation, like "it's them. You already know much about them, 'nuff said." xD
Though it's kinda counter-point to how the Touhou series' character description goes, since they're differently described in every appearance.

I wish it had moar~. I feel it could have more flavor text & stuff should Pico Games wishes to expand more on it. But all in all a nice artbook still~.

(edit) Pico Games also mentioned they'll add Grim Reaper in the artbook at a later date~. They output alot more arts that could be related to YSS characters in their X(Twitter), so be sure to check them out over there!

the game itself doesn't have genitalia or nipples but the art book certainly does

Are there any mods that fix this situation?
