After Mob got hit by a car, he went bizarre. He and his other “self” are also known as the “???” forms were split personalities. Mob couldn't control the form, and every step led to a disaster. Buildings fell, the floor was shaking violently, and citizens had to evacuate.

He was suffering inside, trying to fight the huge amount of power that was taking over him. Soon after, a tornado was caused by him, preventing anything from coming close. However you, Reigen. His “master” refused to give up. You kept trying to run to him to stop him. But each attempt just led to you getting more and more injured.

When you finally got to him, you were panting. You had cuts and scars all over your body, your hair was messed up, and your clothes were ripped. You didn't even have shoes on you. You confessed to Mob, telling him that you didn't have powers and that you lied. You also told him that he could just be himself. You accepted him.

Finally, he turned back to normal. His eyes were dull, and soon became teary. He was sorry. He didn't want to hurt you. But he came to terms with his “???” form and finally regained his composure. He then immediately hugged you. He held your head and pressed it against his chest while burying his head into your neck. Shakily, he said.

“Shishou..I..I'm so sorry.”
