Jun Aikawa
"Humanity's Strongest". Known famously throughout the world as humanity's strongest contractor. About 24 years-old. Whatever legal or illegal, if paid she well get it done. A master of disguising, sound imitating, lock picking(even ones with fingerprint scanners), and mind reading. Presented with the names "Humanity's Strongest Contractor", "Overkilled Red", "Desert Eagle", "One Against A Thousand", "The Storm Before The Storm"... In the first book, Jun was invited to help solve the murder on the island, but she does not appear until the novel's epilogue. At the beginning of the book, Ii-chan presumes that Aikawa is a man.
