Tanaka & Kurebayashi are two characters that are probably the most interesting. It's interesting to note how Tanaka might be on the side for good, but it is clear that he has the feel of an antagonist because he is going against Hikaru & Yoshiki. While for Kurebayashi she is an even bigger mystery and at times seems like a bit of a red flag for knowing so much and not being associated at all.
Though the big backstory was fascinating. Worshiping Unuki-sama started because they were struggling to live on. To add on, it makes sense that after the regions split and the cult is now only active in Kubitachi which is where they are. Though since the name change occurred that is quite odd since that happened before the mass deaths occurred. As we see, the Indou family is the reason. Also interesting thing to see Hikaru losing control of what is inside of him. Honestly, at this point him not being at full power could be in Yoshiki's favor, or it could mean his misery continues.
The big reveal given in the memories of Hikaru when they see the shed with all the heads. Essentially, those were offerings to Unuki-sama. Most of them were people dead. This adds to the statement from Kurebayashi that skulls were missing since they were offerings. To even add on to that point, the different body parts were sent to different regions. More than likely, that could be why they are separated. They are cooperating with Kubitachi even if they aren't part of the cult. The fukked up thing is that travelers would get sacrificed, which is pretty fukked up. Not the worst of it, though.
The conversation between Yoshiki and his dad was good as well. Though where the real issue was the head that was sacrificed was the wife of the man offering it. So if you were to bring back to life the sacrifice then things will go out of wack. Thus, messing with the God's caused the mass deaths that occurred that changed history and Indou's families reputation went down the toilet. Though makes me wonder if that head is the key to stopping the Indou family to continue to apologizing to Unuki-sama. Though curious that he tells his son that he is nothing like him. Granted, they both seem cowardly at the moment.
Hikaru & Kurebayashi's conversation it was interesting to learn of the term majirimono, which, I assume, is mixed. Though it is good to hear that her son is alive. Though the whole mixed term is creepy. The fact that Yoshiki can be partially affected by barriers is concerning. Which makes the decision for Hikaru or whatever is inside him to leave for the mountains to make sense. He is not Hikaru and obviously, he could be putting Yoshiki's life at stake even though Yoshiki is invested. Though when these two are arguing, Tanaka comes up to Hikaru that he is not Nounuki-sama. Curious what disproves that, as a lot of the stories events feel tied for him to be Nounuki-sama
Some good Hikaru moments in this chapter. With Asako he feels guilty about them not being able to mourn Hikaru's death. After all, how can they know that he is not truly Hikaru. Also found the extra chapter interesting because Hikaru is in the position of the monster while Yoshiki is in the position of the princess. Of course, Hikaru sees the monster adapt to humans and live together with them, which is what he wants to do. Of course, Yoshiki hates how the story goes because he would rather see the princess accept the monster for what he is. Of course, that is what Yoshiki ideally wants.
