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.
I have no need to rely on others
to make up for my deficiencies
لستُ بحاجةٍ للعيش بطريقةٍ أعتمد فيها
على الآخرين نظراً لعَجزي
Ich brauche in meinem Leben keine Menschen,
die meine Schwächen ausgleichen.
Yo no necesito compensarle nada a nadie.
Yo no necesito compensar nada con otros.
Je n’ai pas besoin de vivre ma vie
en me complétant grâce aux autres
Non ho bisogno di vivere facendo affidamento 
sugli altri per supplire a ciò che mi manca,
Eu não preciso viver de uma forma que precise 
depender dos outros para as minhas deficiências
Образ жизни с восполнением
недостатков мне ни к чему.
