Hello, Umineko thread. I've recently been re-reading Umineko, enjoying solving the rooms but I can't for the love of me find the order of events for the six-chained one. I saw the supposed or speculated truth on the wiki but it's too vague and just ignores some parts of the explanation.

I understand the basic point. The reason why Kanon is in the chapel is to allow Yasu to dash quickly through the window of the parlor and hide in there as Kanon. No problems with this. My gripe is with the fact that only the key to the chapel is in the Boiler's room. But the only way Yasu has to lock himself inside the church is to have the key with himself which of course is impossible. At the beginning I solved it by simply saying that Genji was alive as well: he is far away in the 4th room of the chain and has plenty of time. He would've waited for Yasu inside the chapel and then locked him inside, completing Kinzo's room before faking his own death. Nanjo of course is in it. But then, Beatrice comes out and tells me Genji is dead and I don't want to push the old "furniture doesn't count" argument to negate the basis of the red. But then, how did Yasu manage to close the Chapel's door? Or is this a duplicate of Episode 2 and the chapel wasn't closed in the first place?
The supposed "truth" on the wiki is so vague, it just tells "oh yeah, Yasu made the circled rooms". I usually wouldn't look but this is seriously the only room I've seen so far I'm having problems solving and I'm going insane
