The revelation of Ichigo's dual Zangetsus in Thousand-Year Blood War marked one of the most significant twists in Bleach.
In the events of the arc, the one who acts as Ichigo's Zanpakutou spirit is White Zangetsu, back then known as Hollow Ichigo.
Following the reveal at New York Comic Con in October, a release date for Asics' next anime collaboration has been locked in.
