Ichigo Kurosaki is the Substitute Soul Reaper protagonist of Bleach. Born to a Soul Reaper captain and a Quincy, his immense spiritual energy allows him to blend swordplay, Hollow transformations, and Quincy techniques to protect both the human world and the afterlife.

Orihime Inoue is Ichigo's fiercely loyal classmate, eventual wife, and mother of his son, Kazui. Boundless in her empathy, she wields the Shun Shun Rikka fairies in her hairpins, granting her a reality-rejecting power that can heal fatal injuries and shield allies from god-like entities.

Uryū Ishida is Ichigo's brilliant, glasses-wearing classmate and rival Quincy. He constantly balances a tragic clan heritage that historically hates Soul Reapers with a deep, unspoken personal loyalty to Ichigo, using a spirit bow with surgical precision to provide critical ranged support.

Yasutora 'Chad' Sado is Ichigo's towering, soft-spoken best friend who swore a childhood oath to use his fists only to protect others. Triggered by Ichigo's leaking spiritual pressure, Chad unlocks demonic, armored spirit arms that grant him the superhuman strength required to fight spirits.

Rukia Kuchiki is the noble Soul Reaper who jumpstarts Ichigo's destiny by illegally transferring her powers to him during a crisis. She becomes his ultimate pillar of support, anchoring his sanity during his darkest moments and bridging the gap between Karakura Town and the Soul Society.

Renji Abarai is a hot-headed, tattooed Soul Reaper lieutenant who starts as Ichigo’s fierce enemy during the rescue of Rukia. He quickly transforms into one of Ichigo's closest brothers-in-arms, sharing a rough-around-the-edges camaraderie and a relentless drive to surpass their captains.

Hitsugaya is the Gotei 13’s youngest captain and a certified prodigy. He has a serious, no-nonsense personality that clashes with his youthful appearance. He wields Hyōrinmaru, the strongest ice-element Zanpakutō. Its Shikai unleashes a massive ice dragon, while its Bankai, Daiguren Hyōrinmaru, grants him icy wings. When the purple ice petals behind him melt, his Bankai matures. This forces his body to temporarily age into a tall adult, letting him flash-freeze any matter or energy instantly.

Byakuya is the elegant head of the noble Kuchiki Clan and the captain of Squad 6. He is the ultimate embodiment of law, order, and aristocratic stoicism. His Zanpakutō is Senbonzakura. In Shikai, the blade splits into thousands of tiny, razor-sharp fragments that look like cherry blossoms. His Bankai, Senbonzakura Kageyoshi, drops giant swords into the ground to summon millions of these blades. He controls them to shred enemies, build defensive walls, or form a winged armor of pure light.

Retsu Unohana is the former captain of Squad 4 in the Gotei 13 and Soul Society's finest healer. She is universally recognized for her serene, warm, and highly polite demeanor, always wearing her long black hair in a prominent braid draped over her chest to hide a deep combat scar.

Rangiku Matsumoto is the charismatic, easygoing Lieutenant of Squad 10 in Bleach, known for her striking beauty and playful personality. She often uses her care-free attitude to shirk paperwork in favor of shopping or drinking sake. Despite her relaxed demeanor, she is a deeply loyal and fiercely capable soul reaper. Her Zanpakutō, Haineko, dissolves into a deadly swarm of razor-sharp ash when she commands it to "Growl".
