A vengeful revenant returned from death following a fatal duel with his younger brother, Renji.​

His complexion is a sickly one, and a dark blight festers across his body. The wound that felled him appears fresh, but no blood runs from it.​

Formidable with the sword and fights with an elegant style. A competent archer.​

​

Possesses a variety of abilities relating to the supernatural; a sixth sense, regeneration, intangibility, and for brief instances can project his soul to attack. So long as Renji's demonic pact exists, Rintaro's soul will remain tethered to the world.​

Reticent, terse, detached.​
