Jin Habari (羽張迅, Habari Jin) was the previous Blue King and the late predecessor to Reisi Munakata.
Novel illustrations depict Jin as a young man with long, light colored hair. SCEPTER 4's uniform was different at the time, so he wore a much shorter jacket than during Reisi Munakata's reign.
In K SIDE:BLUE, he's mentioned to not have been 'decorative in his words', and was a straightforward, honest individual. His sense of justice was strong, and he was willing to risk his life for the sake of others.
Two weeks later, Habari's Weismann Levels went out of control after the Red King Genji Kagutsu's Damocles Down, which resulted in the Kagutsu Crater and death of 700,000 civilians. He asked Gōki Zenjō to slay him before his Damocles Down could occur, thus Habari was decapitated. After his death, the throne of Blue King remained unoccupied for 10 years.
- His name, Habari (羽張, Habari), is derived from Ame-no-Ohabari (天之尾羽張, Ame-no-Ohabari), which is the name of a deity and also the sword which Izanagi used to slay Kagutsuchi; ironically, Habari was not able to succeed in slaying Kagutsu himeself.
