Bleach

Ichigo Kurosaki is a teenager from Karakura Town who possesses the rare ability to perceive spirits. This gift leads him to encounter Rukia Kuchiki, a warrior from another world who is hunting a Hollow—a monstrous lost soul that preys on both the living and the dead. Rukia serves among the Soul Reapers (死神, Shinigami; lit. 'Death Gods'), an ancient order tasked with maintaining the balance between worlds. These guardians ferry departed souls to the Soul Society (尸魂界（ソウル・ソサエティ）, Sōru Sosaeti) while protecting humanity from Hollows. After sustaining severe injuries while protecting Ichigo from a Hollow, Rukia transfers her powers to him, enabling him to assume her duties while she recuperates within a temporary human body. Stranded in the World of the Living, she mentors Ichigo as he navigates his dual responsibilities as a Substitute Soul Reaper and a high school student. Spiritually aware allies join them: Ichigo's classmate Orihime Inoue, his close friend Yasutora "Chad" Sado, and Uryū Ishida, a Quincy survivor with the ability to manipulate spiritual energy.
The Soul Society later apprehends Rukia for unlawfully bestowing her powers upon a human and sentences her to execution. Determined to rescue her, Ichigo and his companions seek the aid of Kisuke Urahara, a former Soul Reaper scientist who trains Ichigo to awaken his innate Soul Reaper abilities. Upon infiltrating the Soul Society, tensions escalate among the Thirteen Court Squads when Sousuke Aizen, captain of the fifth company, is seemingly assassinated. Suspicion falls upon Ichigo and his allies, prompting the Soul Reapers to turn against one another. After Ichigo halts the conflict and secures Rukia's freedom, Aizen exposes his deception, revealing his orchestration of Rukia's execution to extract the Hōgyoku (崩玉; lit. 'Crumbling Orb'), a powerful artifact concealed within her by Urahara. Aizen flees to Hueco Mundo (虚圏（ウェコムンド）, Weko Mundo; lit. 'Hollow World'), the domain of Hollows, alongside his co-conspirators Gin Ichimaru and Kaname Tōsen. In the aftermath, Ichigo is formally recognized as a Substitute Soul Reaper by the Soul Society.
The conflict intensifies as Aizen deploys his elite forces, the Arrancar—humanoid Hollows—against Ichigo and his allies. They are aided by the Vizards, former Soul Reapers who underwent Hollowfication due to Aizen's experiments. When Ulquiorra, one of Aizen's Espada, abducts Orihime, Ichigo and his comrades storm Hueco Mundo to infiltrate Las Noches. Though Ichigo defeats Ulquiorra and retrieves Orihime with the help of his Hollowfication, Aizen reveals his true objective: sacrificing Karakura Town to forge a key to the Soul King's Palace and overthrow the ruler of the Soul Society. The Soul Reapers, anticipating his assault, relocate the town and engage Aizen's Arrancar forces. Gin Ichimaru betrays Aizen but is slain, prompting Aizen to transcend into a near-divine state using the Hōgyoku. Ichigo sacrifices all of his Soul Reaper powers to defeat him, resulting in Aizen's imprisonment and Ichigo's reversion to an ordinary human.
Months later, Ichigo is drawn into a conflict with Xcution, a group of Fullbringers—humans with supernatural abilities—led by Kugo Ginjo, his predecessor as Substitute Soul Reaper. After Xcution manipulates him into surrendering his Fullbring powers, the Soul Reapers restore his Soul Reaper abilities. Ichigo learns of Ginjo's betrayal, stemming from the Soul Society's surveillance and suppression of Substitute Soul Reapers. Despite this revelation, Ichigo reaffirms his trust in his allies and defeats Ginjo, reclaiming his role as a Substitute Soul Reaper.
The conflict reignites when the Wandenreich (見えざる帝国（ヴァンデンライヒ）, Vandenraihi; lit. 'Invisible Empire'), an army of Quincies led by Yhwach, declares war on the Soul Society. After subjugating Hueco Mundo, they launch a devastating assault, killing numerous Soul Reapers, including Head-Captain Yamamoto. Uryū joins Yhwach, uncovering the truth behind his mother's death. In the final battle, Ichigo and his allies storm Yhwach's palace, defeating his elite Sternritters. Yhwach attempts to annihilate the Soul Society, but Ichigo, aided by Uryū and the temporarily freed Aizen, ultimately destroys him.
A decade later, Rukia assumes command of the thirteenth company and raises a daughter, Ichika, with her childhood companion Renji Abarai. Ichigo and Orihime marry and have a son, Kazui, who inherits his father's spiritual abilities. Two years afterward, Ichigo participates in the Soul Funeral Ceremony for Captain Jūshirō Ukitake. While assisting lieutenants in Karakura Town to capture Hollows for the ritual, they are ambushed by the Beasts of Hell, led by the resurrected Espada Szayelaporro Granz. Though the lieutenants repel the attack, it is revealed that the ceremony serves as a means to consign deceased captains, including Ukitake, to Hell.
