The series follows the story of Ichigo Kurosaki, a teenager with the ability to see ghosts, who becomes a Soul Reaper after accidentally obtaining the powers of one. Ichigo is tasked with protecting the living world from evil spirits and guiding the souls of the dead to the afterlife.

The Thousand-Year Blood War arc is the final story arc of the Bleach manga series. It was originally planned to be serialized in 2010 but was delayed until 2012 due to Kubo's health issues.

The Thousand-Year Blood War arc introduces several new characters, including the leader of the Wandenreich, Yhwach, who possesses the power to steal the Bankai abilities of Soul Reapers. The arc also explores the backstory of the Soul King, the ruler of the Soul Society, and his connection to the Wandenreich. The Thousand-Year Blood War arc has been adapted into an anime series, with its release date still unknown.
