Sentarou Kotsubaki

Sentarou Kotsubaki serves as the acting lieutenant and co-third seat of the Thirteenth Division. He holds a deep respect for Captain Jūshirō Ukitake and wears fisherman-style braided ropes on his uniform that set him apart from other Soul Reapers. While he is a capable combatant, he spends much of his time in heated verbal disputes with his fellow third seat, Kiyone Kotetsu, frequently using insulting nicknames during their arguments.
