Analysis:Execution of Utsumi's Plan End

Mystery of the Newspaper
In "Execution of Utsumi’s Plan" End, the contents of the newspaper are rewritten. According to it, Kokoro and the others were killed at the time of the plane crash.

But considering the Many Worlds Interpretation, it's not so strange.

The world of "Execution of Utsumi’s Plan End" is different than the world of 2011 the player is experiencing. In the world of 2012, the truth of what happened in 2011 became uncertain. (For more information, refer to the page "Does History Change?")

Maybe the bad ending caused the world of 2011 and 2012 to come from two separate worlds.

Mystery of the Bloody Writing
Why did Utsumi write "Where is Self" in this ending?

Considering that she removed Inubushi's heart, it seems exacted her revenge by mimicing Inubushi's behavior during the Awazumi Hospital incident. Utsumi gave her a taste of her own medicine, so to speak.

Escaping the Infinite Loop
On the 4th day of Satoru's route, Satoru can fail in stopping Utsumi's plan for revenge. This causes Satoru to become insane. As a result of his mental illness, he was hospitalized.

"Enomoto-saaan, Enomoto Naoya-saaan, it's time for your medicine..."

Let's look at it from the player's point of view. Even though the player's consciousness should have returned to the 1st day in the final level, Satoru acknowledges that he is in this institute.

The player's consciousness went to a point in time that's outside of the main story. In other words, it escaped the infinite loop.

However, the player doesn't realize they are trapped in an infinite loop. Therefore, "wanting to redo the bad end", the player returns to the start of the main story.

The "Peace of Mind, Alone in the Shelter Cabin End" is similar.

Kokoro's Route Epilogue
The player's consciousness jumps to the future in Kokoro's Epilogue. It's probably similar.

The player wanted to know what happened after Kokoro's route, so they jumped to July in the same world. The player slipped out of the infinite loop, but returned to January 11 to see the event through Satoru's eyes, not knowing they are in an infinite loop.
