Кіріхара Рейджі

The youngest son of the once well renowned Kirihara Family: Reiji Kirihara. Once training to be a swordsman with his twin brother, Shinji, under their father's teachings. Now, among a family in ruin, Reiji stands out on top, working as an Onmitsu for the Bureau.

Compared to other members of the Black Torch elite squad, Reiji presents himself to be much more calm and collected, rarely letting other emotions get the best of him. Similar to Ichika Kishimojin, Reiji has a distaste for Ragou and Jirou Azuma at first, though they get closer over time. Though Reiji seems to be somewhat of a gentleman, he is easily excited and flirty towards women.

After the Kirihara Family incident where Shinji killed his and Reiji's father and several others, Reiji was forced to live with what happened. He and Shinji cross paths several times, each with Shinji saying one must die. Despite this, Shinji does spare Reiji twice, though it won't happen if they meet again. After the events of the Amagi incident, Reiji gains a special blade that will be ready for his and Shinji's final showdown.
