Ran Izumii

泉井蘭

Older brother of Kuronuma Aoba, does not like his younger brother at all. Aoba had always acted all smart and appeared highly aware of other people's needs, which somehow never failed to stir a weird kind of annoyance in Ran. Ran was Blue Square leader during conflict with Yellow Scarves, that happened one year ago. After that he starts working for Orihara Izaya.
