So what we got now is the Clock Keepers holding a trial and is trying to point out who is the cause of the issue at hand. I guess in some ways it shows the power of their boundary. For Hanako and Teru we know it makes no sense for either to be the cause. Hanako's priority is figuring out how to deal with Nene's lifespan issue. Trying to go against the Clock Keepers goes against him. Meanwhile, for Teru for him, he wants to get rid of supernaturals as an exorcist. But he would never create more problems for himself and put his two siblings in danger. For Nene we know she wouldn't have ill intentions to stop time. As she is a very idealistic person. Though I love how it gets revealed that she was going to confess to Hanako.
How blunt Tsukasa can be both interesting and weird. Though what he mentions helping Sakura. Essentially, she is his Nene. Still, when Tsukasa fights back it just leaves to wonder why he waited. Though this is all a game to him. As he attacks Kako he is left to wonder where their Yorishiro would be. Although interesting enough the Yorishiro was in Mirai. Considering that in this domain Kako can rebuild himself instantly, it makes you wonder why Mirai is his Yorishiro, perhaps.
Now all the pieces are in places for Tsukasa. We know Mitsuba doesn't have a Yorishiro yet, and we know Tsukasa is Hanako's Yorishiro as the last one since he holds the Clock Keeper's Yorishiro. Though Natsuhiko's conversation with Mitsuba was rather dark. Just what is he, and what is this curse? Though it is even evident to this day that Hanako cares for his brother. The issue is: What is Tsukasa now as we know from his past? Though it seems this was part of the Clock Keeper's plan all along. Their goal was to fix the root of the problem because, as we see in the scene with them and Nene the root can make a plant ugly. Replace that root problem and it is beautiful. We can see that the thing inside Tsukasa is the same thing that Akane's family was sacrificing brides to keep them safe. As we know, that areas is connected to the bottom of Tsukasa's house, which is how he came into contact with it to make a wish and save Amane.
Preventing Tsukasa from becoming the thing's entity seemed to have some effects in the present. The first is Nene. Who is now the star of the play. The old Nene would never have been in this position. Thus, we can think of it logically as this is a present she would favor. There was one thing special about the previous present and that was her time with Hanako and Kou. Judging the scene with Tsuchigomori at the end, it seems clear that in this present Amane's future didn't change. Thus, he became a teacher at the school for a time and never became Hanako. As we see in Teru's conversation with Akane, that some people retain their old memories temporary. At least what will Nene and Teru go from here?
