Through his conversation with the Little Rice Princess, Chen Yu learned a lot of useful information and also came to understand the current situation of Saegusa Kyoko.
In Japan, Yomi had long existed; from the information Chen Yu gathered from the Little Rice Princess, he felt it might be a corner of the Underworld in the Central Region, simply occupied by the Yomotsu Oni Tribe and turned into the realm of the dead for Japanese Shintoism.
Of course, the origins of Yomi weren't important; tracing back thousands of years to the age of myths was fine for story-telling, but delving too deep would seem exceedingly tedious.
For contemporary Japan, Yomi still represented a place of rest and rebirth for the deceased. As for the Pure Land, it was believed by those who followed Buddhism that if one died without any worldly attachments, they could be reborn in the Buddhist Pure Land.
