- Severe
- In most episodes, a fight of some kind or another occurs. They can range from somewhat mild to very graphic in nature.
- A character is graphically burned to death by corrosive acid.
- Many characters have special powers that allow them to use their blood as weapons or armor. However, they usually must cut or injure themselves first in order to use such powers.
- Weapons of all kinds are used in the series, such as swords, pipes, guns, bombs, flamethrowers, knives, and others. When they are used on someone, the end results are usually graphic and bloody.
- After having his arm mostly sliced off, one of the protagonists rips the remainder of it off and throws it at the person responsible, a young girl. The severed limb strikes her in the head, leaving a bit of blood on her face.
- A boy's entire class is massacred by an unknown killer. He wakes up to find the classroom dark while blood covers the entire room and the bodies of his classmates lie strewn about the room. The killer then holds up the head of one of his friends and throws it at him (barely visible in the cut version because of the darkness). He screams in terror as the killer shoots something into his chest and he passes out.
- A guard slashes a prisoner's shoulder with a sabre, and blood gushes out of the wound.
- There is a game called the "Carnival Corpse" that the prisoners have to compete in. Numerous prisoners die. The deaths are very bloody and graphic even in the censored version, since the scene takes place during the day so there is no darkness to obscure what is going on.
- Surviving losers of the organized fights between blood-users (Deadmen) are forced to play a sick game for punishment. A slot machine labeled with the names of body parts spins and the loser specifies when to stop the slots. Whatever body part the machine comes to rest on is amputated from the victim by doctors as a reminder of their failure. Through this process, a man's eyeball is ripped out of its socket with little to no censoring. Later, flashbacks to the slot machine explain the absence of various parts from character's bodies.
- One of the antagonists murders a pregnant woman by cutting her open with a blade. It is shown briefly and in shadow, but can still be disturbing to some.
