Itami and Kurushimi Setsudan

Background
From birth, Itami and Kurushimi were joined at the hip. Literally, as they were conjoined twins. However, they doctors were able to separate them, and they were normal babies. However, they were the sons of Mania, the goddess of insanity and murderers. They were practically destined to kill. And kill they did. Their first murder, though unintentional, was on their kindergarten teacher, Ms. Takahata. They were pranksters back when they were kids. The prank was she'd walk into the classroom, and step in a bucket of water. She would kick off the bucket of water, pulling a string which would dump a bucket of water on her head. However, when she kicked off the bucket of water, she slipped and fell. She hit her head on the floor, knocking her unconscious. When the water fell, she couldn't spit it out, and she drowned in it. After that, they ran away. They survived for a year by killing small animals and eating them. One day, they were found by Lady Chaos, who came to them as "Kami-Sama" (God), and told them they needed to serve her. To this day, they commit murder after murder, enjoying every second of it.

Appearance
Itami and Kurushimi are identical in every signal way. They both have neat orange hair, and handsome blue eyes. They usually wear the same exact clothing, too. A white long sleeved shirt, with a brown sweater best over it. They wear black dress pants, and combat boots as well. The only way to tell them apart appearance-wise is what side of the body their scar is on. Itami has the amputation scar on his left hip, while Kurushimi has it on his right.

Personality
Itami: Itami is the calmer of the two. He plans his murders out with no flaws. He's also the "nicer" of the two. He shows slightly more remorse for killing than Kurushimi does. But it's still not a lot of remorse. He also chooses who he kills based on if he likes them or not. This suggests that he's friendlier than Kurushimi. When murdering, it's mostly women, using his charm to attract them so he can "show them a good time" before he brutally murders them.

Kurushimi: He's the less sane of the two. He goes for a murder if he knows off the bat he can do it. However, his social life is very similar to his brothers. He's friendly, suave and a good speaker. However, he's not afraid to openly state he'll kill someone, though most people think he's saying it out of anger. He likes to torture victims before killing them with lethal injection.

Abilities
As sons of the murder goddess Mania, they're top notch killers, never getting caught and convincing police it wasn't them if they do get caught. Itami prefers more natural weapons, such as his trusty AK-47, and his trademark giant cleaver. He sets up piper bombs in order to destroy evidence, or make a quick kill. Kurushimi, on the other hand, uses his special torture tools, namely his knife and spiked whip. He's very good at wielding these in a fight. When torturing a foe, he straps them onto a wooden board, and drives nails into the fingers of his victim. He also uses Iron Maidens if he's bored that day.

Fatal Flaw
Despite being such good fighters and killers, they're just so insane that it can sometimes get in the way of their better judgement in a fight.
