Adult PC Game: Natyusyo - Yuka - Scattered Large Youkai Fragments Version 1.07 (eng) Archive

Due to Kappa's blundering work, the reason and common sense of Yuka have crystallized and scattered all over the place!
A villager who can see the crystals that usually cannot be seen happens to be there and he will be forced to collect pieces!
The fragments collected can be easily broken by tapping, losing Yuka's reason and common sense, and the guard is looser and looser...!!
