Mastermind Makoto Naegi

Mastermind Makoto Naegi
In the AU, Makoto Naegi was found to be the Mastermind when Kyoko went into his room after his "execution" (the After School Lesson) and was going to search for clues.

Instead, she found a sleeping Makoto in his bed and a group of monitors and a speaker. While searching through the monitors, she found that there was a TV displaying live footage of this outside world, which was just the killing games. Makoto woke up and they fought each other for a while before Kyoko began to strangle Naegi. She then let him go because of her feelings for him. But he then ran away, yelling that Kyoko was the mastermind.

Later, Hina was yelling at Kyoko before Kyoko explained everything to the survivors ( Leon, Byakuya, Mondo, Hina and Junko ) and then Naegi entered. Kyoko and Byakuya tied Makoto up, put him into a barrel, and closed the lid. They grabbed a bunch of swords and impaled Naegi from the outside. The two checked to see if he was dead, but then he said with his last words that The Tragedy did this to him. They patched his wounds back up and forgave him for what happened because he was misunderstood, not evil

The Survivors Escaped in this AU idk
