Jin Shiba (司馬迅, Shiba Jin?), known also as Shun (隼?), is a prisoner on death row for patricide and is Jyusan-hime's ex-fiance. Jin is one of the many assassins sent after her and Shūrei Hong after he was released from prison and being pardoned by the three oldest Ran brothers. He is from the Shiba clan, a subsidiary clan of the Ran clan.
He was a childhood friend of Shūei Ran and Jyūsan-hime Ran and the one who gave Jyūsan-hime the nickname "Hotaru". He met Jyūsan-hime when he was eleven years old, shortly after Jyūsan-hime's mother was murdered by his own father. Jin had been sent to the house to kill her but could not bring himself to do so. Jyūsan-hime, who had been three years old, sat by her mother's corpse and stared at Jin for three days and nights. When she finally told him to come closer to her, he cut out his eye and gave it to her as a symbol of trust. After the incident in Ran Province, he winds up wandering the countryside with Shusui.
