He is one of the main protagonists of the anime and web manga series. He is in Nanba Prison for unknowingly buying and selling drugs in the slums.

~!Born in the slums of America, he was born with an unusual condition that gave him strange allergies and illnesses. He was arrested for carrying and selling drugs. However, when the doctors checked his body they discovered he did not digest any drugs and was more than likely used as an unwitting courier. He was sent to juvenile hall with a light sentence and was later sent to a medical reform school to receive intensive care. However, whenever doctors tried to examine his body to treat his unusual illnesses and allergies he would get frightened by the needles and their medicine and frequently broke out of several hospitals and jails, increasing his sentence time. He is currently sentenced for aggravated escape due to the extent of the damage.

At an unknown point in time, Nico was used as a recyclable test subject as his body is able to return to normal after being injected drugs and medicine. Due to the multiple experiments performed on Nico, his brain had suffered damages, causing his body to be unable to limit the amount of strength he uses. Due to this, Nico has to take medicine to avoid destroying his own body.

At some point, he met Jyugo at a prison and then later met Rock at a different prison and became good friends with him. Later he was captured and taken to Nanba Prison and since they have some of the best doctors and medical care in the world, the doctors there give him drugs and medicinal pills to treat his illnesses, he does not feel like escaping and ironically became somewhat a drug addict.!~

Four men are assigned to the prison: Juugo, a man who attempted to break out of prison and ended up extending his jail time; Uno, a man who likes to gamble with women; Rokku, a man who likes to get into fights; and Nico, a man who likes anime.
