Bleach: The Sealed Sword Frenzy

Baishin, a dangerous Soul Reaper sealed away by Soul Society long ago, escapes into the human world and begins cutting a path of destruction. Ichigo encounters him before understanding the threat and loses a large portion of his spiritual pressure in their clash.

Weakened but unwilling to stand aside, Ichigo joins the Soul Reapers hunting the fugitive. Baishin's strange power and the reason he was sealed make the pursuit increasingly dangerous, forcing Ichigo to recover his strength before the former prisoner can turn his freedom into a catastrophe.
