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.
Apparently, I'm now in a situation 
where anyone can betray me.
يبدو أنّني في ظرفٍ يخونني فيه الجميع الآن
Wer weiß, wer mir als Nächstes
in den Rücken fällt.
En esta situación
puede traicionarme cualquiera.
En esta situación
puede traicionarme cualquiera.
Je ne peux même plus dire
qui m’a trahi ou pas.
E così mi trovo nella situazione in cui chiunque 
è potenzialmente un traditore.
Parece que estou numa situação 
onde todos podem me trair.
Уже даже не знаю,
кто следующий меня предаст.
