From the looks of it, giving Chiya alcohol is a very bad idea.
It seems that the girls dress up as brides for a festival that is happening in the town. Apparently, the gods went around and choose which girl to marry. With that, the girls dress up in kimonos. Chiya doesn’t like being dressed up for obvious reasons, but she has no choice. With that, the girls have fun eating food and such, there is one thing that causes Chiya to act strangely.
Surprisingly, chaos ensues when the girls discovers ritual wine. They decide to try it and of course, the smell got to Chiya. She started acting crazy as animals becomes attracted to her due to the pheromones. Eventually, Chiya ambushes Saku and licks her face. I guess Saku should be used to the chaos given that she experienced it before. Then again, she probably secretly enjoys having Chiya licking her.
Aside from that, Chiya eventually went up to a hill and saw a strange black creature. When she tried to talk to it, she eventually collapsed. Saku eventually found her and brought her back to Nina. I find it funny that Saku thought that Nina will show her belly when Nina meant something else. It seems that a bit of Chiya is rubbing off on her.
With that, it seems that the wine and sleeping on a hill has caused Chiya to catch a cold. While it’s not so surprising that Chiya doesn’t know about colds, at least Kon spent time with her. She fed her rice portage and served her tea. It’s quite obvious that she is trying to win over Chiya’s favor. Not so surprising since she revealed that she studied hard to become the best Urara. Before she can ask her about the creature, Chiya fell asleep.
From the looks of it, Kon now thinks that Chiya can see gods. This is why she is worried since everyone will surpass her. Thankfully, Nina came to reassure her that it’s okay to compete with her friends. Maybe someday, Kon will see a god just like Chiya did. Patience is key.
