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.
Just imagine that when you're under 
this umbrella, you're in your room.
تخيّل فقط أنّك عندما تكون تحت هذه
المظلّة، فكأنّك في غرفتك
Stell dir einfach vor, dass dein Zimmer
unter diesem Schirm ist.
Piensa que tu habitación
está bajo el paraguas.
Piensa que tu habitación
está bajo el paraguas.
Imagine qu’être en dessous
revient à être dans ta chambre.
Immagina che quando ti trovi sotto quest'ombrello
sei di nuovo in camera tua.
Imagine que, quando está sob ele,
está no seu quarto.
Считай, что под ним твоя комната.
