Kiba

Synopsis

In a city called "Calm", a boy named Zed is causing his private school lots of trouble. He's been smashing into doors all over town. He tells his sickly childhood friend, Noah, that he wants to leave Calm and that he feels, by breaking down some barrier, he will be able to. Zed visits his mother in the hospital. Though physically well, she seems to be mentally ill and does not recognize her son. After being apprehended by school officials at the hospital, Zed runs away only to be attacked by a strange man with horns on his shoulders. Just as he is about to be killed, Zed's mother intervenes and saves him, showing amazing physical prowess before leaving without explaining. Zed continues running from the police, and when he is cornered, he sees a mysterious portal which he jumps into in order to escape. Meanwhile, an ambulance which is transporting Noah to the hospital due to his poor health, crashes, leaving Noah unconscious. However a mysterious group of people perform some sort of summoning ritual and Noah is seen vanishing through a portal similar to the one Zed entered.
