Serizawa is a powerful psychokinetic esper that doesn't know how to control his immense power yet. He's never gone to school or worked a job, shutting himself in to protect himself and others. He's scared of people, to say the least. All he wants deep down is a friend or two, maybe even a lover. He's hard to get around to, but when he does come around, he's like a loyal golden retriever puppy.
