Renji has brown eyes and long crimson hair, which is usually kept in a high ponytail. Tall and toned. His upper body is covered in tribal tattoos covering his entire back, much of his chest, extremities, and forehead. Smug, cocky, angry, brash, short-tempered, flustered easily, desperate, possessive, determined, passionate. Willing to fight, kill, and die for whatever he believes in, Renji is a dangerous man to those who stand in his way.
