Jun Aikawa (哀川 潤, Aikawa Jun), also known as Humanity's Strongest (人類最強, Jinrui Saikyō),
Whatever legal or illegal, if paid Aikawa will get it done. She hates being called by her last name as only her enemies call her that. She has a strong sense of justice, and trusts her friends very much. She hates leaving things half-assed, a trait that makes her bother I very much.
She is a pretty arrogant individual. She is described by Hikari Chiga as being "angry at the world" for not being up to her standards. Many individuals fear her name, and there are many over-the-top stories about her feats.
Aikawa has shoulder-length red hair with a yellow lightning--shaped strand of hair on the front, an red eyes. She is very tall and according to I, very beautiful.
Aikawa wears a red suit with a blue undershirt and thigh-high red high-heeled boots.
Aikawa was born in an experiment led by Takashi Saitou that aimed to create the strongest human. She was abandoned after she was deemed as a failure.
The Beheading CycleEdit
After I and Tomo Kunagisa returned to Kyoto from Wet Crow's Feather Island, Aikawa visited Kunagisa first and then went searching for I. After she found him, she forcibly took him with her in her car and explained the solution to mystery to him. After her explanation was over, she encouraged him to not leave things half-assed, and dropped him off at Kunagisa's house.
She was hired by the police to put an end to Hitoshiki Zerozaki's rampage in Kyoto. She dropped by I's house and forced him to tell her what he knows about the serial killer. After getting what information she could, she got into a fight with Hitoshiki, who barely managed to escape.
After Hitoshiki left Kyoto, Aikawa followed him, but they came to an agreement that if Hitoshiki stops his killings, she will let him go. Hitoshiki agreed, and told Aikawa about I's conclusion to the mystery. She later dropped by Kunagisa's house when I came to visit, and made him spit out the complete solution to the mystery, and then encouraged him again to not leave things half-assed, before leaving.
