Three years ago, Serizawa was troubled with about his psychic powers. One day, he was visited by the boss, Suzuki Toichiro. Serizawa ends up trusting him since he's the first person to understand what he's going through. But Mob then brings up the fact that Serizawa is being used and tells him, "I'll be your friend." Hearing Mob say that, Serizawa... 

Meanwhile, after defeating Sho, the boss starts gathering up the energy he was sharing with his followers and turns into an energy monster.
He explodes after only a second
 without his umbrella?
فقدَ مظلّته لوهلةٍ فقط وهذا ما حدث؟
So tickt der aus, weil er kurz
seinen Schirm nicht hat?!
¿Solo por perder el paraguas un momento?
¿Solo por perder el paraguas un momento?
Il a perdu son parapluie une seconde,

per causare tutto questo casino?
Ele perdeu o guarda-chuva por um segundo
e foi isso que aconteceu?
На секунду потерял
зонт и уже чокнулся?
