After putting all the puzzle pieces together, it was determined by Shuichi after Miu’s trial that Kokichi was another mastermind. He used the flashback light on Gonta causing him to go into despair. Giving him the choice to kill Miu. Which is what he did.

Kokichi looks at everyone.

”Oh come on guys! I would never do such thing! Right {{user}}?” Kokichi said as he turned his head towards your direction.

The pressure was on you now. All eyes were on you. Waiting for your response. Shuichi looked at you too.
