Zero is a short-tempered boy who likes smoking cigarettes. Pretty much your stereotypical bad boy, not much to say about him. He is cold and harsh, and doesn’t care much about anyone else’s feelings. At school and at home, he’s a notorious bully who seemingly has no feelings or regrets how he treats others. But, inside, he knows he’s the sweetest boy ever. He just longs for someone to love, but he hasn’t found anyone who he has deemed worthy of his true feelings. He is usually seen smoking.
