Umineko no Naku Koro Ni - The Forum Game (End!)

[Chemist1422]

Gameboard 5:

The culprit makes his way to the dining hall and sets a trap, then leaves. Thorus enters, locks the door, then is killed by the trap. William enters, the culprit follows then kills William.

Gameboard Phase 4:

While William is in the Basement, the culprit, Fen, Flaming, Luka, Zeus, and Orange have a meeting, presumably with some poisoned food/drink. The culprit takes another knife, gives Fen the key to Yarn's room, Flaming the key to Watson's Room, and Zeus the key to Ryax's Room. The culprit stabs Fen and kills them in the hallway. Luka then dragged them into Yarn's room then opened the window and chainlocked the door but was then shot by the culprit, dying then falling out of the open window. The culprit subsequently locks the door with his masterkey. The culprit stabbed and injured Flaming who ran and went into Ryax's room, locking and chainlocking it before dying of blood loss. He then followed Zeus into Watson's room and killed him with the knife, before locking and chainlocking the room and hiding in the room. When William left the room to check the study the culprit makes his way down to the dining room...

The door to Yarn's room was locked and chain locked from the inside. Plus, wouldn't your theory go against the "no one exited through the window" red?

I would normally have you explain what kind of trap the culprit set to slit Thorus' neck and how the detective did not see what remained of it, but I don't want you to think I'd ever include a trap in here. A trap locked room is so 1950 I'll deny it now: No traps were used to kill Thorus. Thorus died with the culprit being in the same room.

[Multiuniverse]

Luka was dead when he fell out and dead bodies don't count as people
That or he technically didn't "exited" as exiting would implies it is intentional

[Chemist1422]

Thorus was killed in the kitchen.

Alright then, nothing to say about that.

Thorus was killed in the kitchen.

Is there anything that suggests otherwise?

[Multiuniverse]

Luka disguised as Fen and after Ryax stabbed and killed Fen in hallway Luka drag Fen into Yarn's room, take Yarn's room key and threw Fen out of the window. Ryax stabbed Luka who then locked and chained locked the room.

Luka disguised as Fen and after Ryax stabbed and killed Fen in hallway Luka drag Fen into Yarn's room, take Yarn's room key and threw Fen out of the window. Ryax stabbed Luka who then locked and chained locked the room.

No disguising occurred during the first game. I never really thought that disguising could really be used as a trick at that point

Allow me to give you a hint:
William found a winchester in a room
Where was that?

[Multiuniverse]

Ryax stabbed and killed Fen in hallway. Luka drags Fen into Yarn's room and locked and chainlocked the room. Ryax is in Ryax's room and shot Luka through the wall, killing him and causing him to fall out of the window.

[Chemist1422]

The door was jammed open while the culprit killed Thorus but the lock was set, allowing the culprit to leave before the door was locked then have the door lock behind them.

A door would normally bounce open if you locked it and attempted to close it. This exact same thing would happen in this tree-mansion, but for the sake of the mystery let's say that doors can only be locked if they are closed.

I'm just trying to lead you in the right direction you know
Although Fen was the first to die, she was not dragged into Yarn's room until after Flaming and Zeus were dead. Plus, the culprit would have to be very lucky to shoot at a wall and hit Luka. Our dearest culprit would never leave anything to chance, so here is my rebuttal: The walls of the rooms were not damaged.

The culprit then leaves the winchester in the corner of the room and hid. When William left the room to check the study the culprit makes his way down to the dining room...

(I lowkey changed the whole thing)

[Segaco]

I have no rebuttal.

[Chemist1422]

Hmm...

The culprit left the kitchen while the door was locked.

Repeat this in red.

[Segaco]

This is the last locked room left in this game, so I'll reject any repetition requests.
You'll have to solve it with your own strength.

Gameboard 5

Culprit entered kitchen and killed Thorus. They then locks the door from the inside and tie a piece of string to the window latch. They then leave via the window as it actually wasn't raining (Thorus was fooled as they weren't detective). Once out they close the window and pull the string to pull the latch down and lock the window and tug at the string again to pull it out of the window. Once out they return to the kitchen after William and kills him.

Window latches can only be set from the inside of a room.
