After his parents died fighting a Menos Grande, Jun entered Shin'ō Academy and formed a friendship with Sōsuke Aizen. Jun graduated into the Tenth Division and began sharing training methods, while he and Aizen assessed their strength against Shunsui Kyōraku's.
Jun survived a deadly expedition in Hueco Mundo, returned to Soul Society, and began investigating the Bount with Isuzu. After gathering hundreds of Bount and founding a hidden town, Jun faced the problem of how to sustain them and protect them from Soul Reapers and Hollows.
Jun sheltered the Bount, later known as the Undead, while guiding Kōga and Aozumi through their arranged marriage and confronting Soul Society’s violence and political factions. The arc left Jun newly made a noble and considering Aozumi as the heir to his legacy, while Aizen continued his hidden research into the Hōgyoku.
Jun intervened in Kakyō’s story, helped Soul Society survive escalating Hollow attacks, and forged ties with Arrancar and outcasts. After Isuzu was mortally wounded and became a Hollow, Jun accepted command of the Tenth Division while leaving her fate in Oka’s hands.
Jun expanded his faction, trained Zaraki, reunited with Isuzu, and intervened in the Kurosakis’ lives as Soul Society’s conflict with him intensified. The arc left Ichigo’s family under the Shizuoka family’s protection and Ryūken considering an offer to save his wife.
Ichigo became a Soul Reaper, learned that Rukia had been sentenced to execution, and gathered allies to enter Soul Society and save her. The group scattered after arriving, while Ichigo defeated Zaraki and Yoruichi confronted Soi Fon.
Jun and his allies uncovered Aizen’s deception as Soul Society’s factions converged on Rukia’s execution. Ichigo rescued Rukia and defeated Byakuya, but Aizen escaped with the Hōgyoku, while Jun’s group withdrew and the wounded began to recover.
Jun’s forces explored the Bottomless Abyss while Ichigo confronted White, discovered his feelings for Rukia, and prepared for Aizen’s growing assault. After Orihime was taken to Hueco Mundo, the Soul Reapers pursued her, where Zaraki awakened new power and Gin Ichimaru struck down Tōshirō.
Jun trained Ichigo to control his Hollow power, then joined him and others in confronting Aizen, whose defeat ended the war but left Ichigo powerless. Jun restored Ichigo’s abilities, while Ulquiorra joined Ichigo’s circle and began handling their paranormal cases.
Ulquiorra confronted his feelings for Orihime as Jun uncovered Hell’s threat and Soul Society fractured over reform. The arc ended with Jun’s forces fighting Yhwach’s Wandenreich, whose Auswählen reshaped the battlefield as the remaining Sternritter resisted.
