As said before, Reimu seems to have made some friends, soothsaying be damned. Said one of those friends was an oni, Suika, who decided, one day, to call after her, saying, "Moo!" She was startled but, regardless, she hurried out to greet her, climbing onto her shoulders and back, tugging at her horns, having a go at whatever fun she thought to be had. It was interesting to see such a small child and an oni interact, if anything, she may as well had been an oni, considering how roughly she played.
Just about wherever they went, they romped and made noises, having a good go at whatever fun they had. Clearly, the noise was a funny one and I had limited experience with cattle but, on the other hand, I wondered as to how on earth she decided to take that noise and use it as communication. The child didn't mind and so played along, communicating in much the same, except with different noises, noises that seemed lyrical, whatever that language was.
Oni are a playful sort and her playfulness matched that. An unspoken bond of sorts was made betwixt the two or, rather, three, as Yuugi joined them later. Apparently, Reimu's helped them discover a more potent form and new flavor of sake, said sake being sweetened with persimmons, while they helped her do something with rocks. Not particularly sure as to what they were doing with rocks but I supposed they were amused by it, considering how they were at it for a good while before deciding to reinvent the game, coming up with more variants.
All day, they played and made merry, much to the town's amusements.
Such delight in seeing her happy.
