This thread is to discuss what the fuck could be going on in this anime. You’d better have watched all eight episodes >:(
This spoiler pertains to episodes 5-8:
[spoiler]Mion-Shion switch:
Here’s what a friend and I came up with.
Let’s call the good girl that Keiichi knows and goes to school with, and the one that really likes him, Mion. Let’s call the evil psychotic twin Shion. The younger sister, however, has the Sonozaki family inheritance tattoo whereas the real successor doesn’t.
The theory goes that Shion is the elder twin, and the successor to the Sonozaki family. Mion is older sister in name only, and doesn’t do much in terms of yakuza business. Shion is the one that went with Keiichi into the shrine, and consequently knows about everything. Why? In the tea-bringing scene on the night of the festival, Shion seemed quite the extortionist. She embarassed Mion but Mion didn’t say anything about it.
After the shrine adventure, Shion mentions a “bang-bang” sound. This could be a test to see if Keiichi noticed something, possibly the forbidden thing that was a big enough secret to kill both Takano and Tomitake.
Mion tries to give a hint to Keiichi to leave Shion alone afterwards, but Keiichi kinda ignores it.
Shion comes to school to see if what kind of response Keiichi gives when he’s asked about being with Takano and Tomitake. He gives a sort of vague response, so that’s good, but then she asks if Keiichi was with Shion last night. Keiichi replies by saying, “Didn’t you ask me that yesterday?” and so shows that Mion suspected something. She then goes off and basically says that she’ll protect Keiichi. Since she’s head boss 'n shit of the entire town, Keiichi stays alive while the other three eventually disappear.
Later, he meets with Mion in the library. She wanted to talk about Takano and Tomitake’s deaths, but couldn’t say it in front of the detective. She later phones Keiichi to talk about it, but Keiichi goes ape-shit crazy on her. She gets angry. She also does something that we don’t know about, except that it made Shion really, really mad.
In the next episode, Rika mentions that both the elder and younger sister “cats” are angry, and that it’s probably a good idea to leave the elder “cat” alone. So Shion is really pissed off, probably by the “evil act” that Mion is supposed to have committed. At this point I think the storywriters are trying to throw us off and make us think that going into the shrine was the evil act, but I don’t think that was that big of a deal, especially since I think that Shion is the one who led them in there in the first place, and Mion is supposed to be the one who had done the “evil act.”
Maybe the “evil act” involves both Mion and the village elder, who is conveniently head of one of the three families. Those two mysteriously disappear. What happens after Rika’s conversation is all Shion. For the scenes that aren’t Shion (i.e. the Rika/Satoko investigation scene where she flips out), it’s her posing as Mion.
It is Mion who’s in the prison cell. Shion put her there, and after she knocks Keiichi out, she kills Mion, disguises her as herself, and puts her in the well where all the other dead bodies are. She then gets “rescued”, and stabs Keiichi in the stomach. I think then she poses as Shion, jumps off the building, but doesn’t quite die, and maybe is taken to a morgue that is in the same hospital as the one Keiichi is recovering in. That explains the blood on her face and hands in the end.
Of course, this doesn’t explain how Takano is supposedly “dead” the night Keiichi and co. went into the shrine…[/spoiler]
