Deep with ruins monks perform an act of sealing upon a shrine that explodes, killing all the monks as a mysterious figure emerges from the shrine. Menwhile, Ichigo plans to rest away his Sunday morning with Rukia and Kon until Yuzu arrives to reveal an officer was attacking Isshin. After discovering Renji was the officer, Ichigo and the others visit a fast-food resturant (that Hanatarō works at) where Renji reveals the Soul Society sent him on an ergent mission. Before this can be explained, the being from the ruins attacks the town and proves a formitable advercary when he brutaly injures Ichigo. At which point, Hitsugaya arrives to keep the being at bay.

At Hitsugaya home, he reveals that the being is a Zanpakutō-laking Shinigami named Baishin, who terrorised the Soul Society until they sealed him away forever...or though it seemed. At which point, Soul Society members arrive to take action (excluding Kenpachi and Yachiru due to navagational problems). The group splits up around the city to take on Hollows summoned by Baishin. Ichigo, Rukia, and Renji arrive at the the ruins to find Baishin, who drains Ichigo's spirit energy to the point of passing out. When Baishin attemps to kill Rukia, Renji arrives to take the blows and use the last of his energy with Higa Zekkō on Baishin, who is left weak until he enters a bankai form.

With Rukia and Renji defeated, Hitsugaya arrives and attemps to overpower Baishin with his bankai form, but fails. With the group too late, Baishin prepares to kill Hitsugaya until stopped by Ichigo, who regains conciousness and proves more formitable. Within the climax of the fight, Ichigo enters his bankai and easily overpowers and bifercates Baishin, who's Zanpakutō falls to the ground. With the fight over, Ichigo reveals that Baishin was one with his Zanpakutō and wanted his body back. After having breif simpathy for Baishin, the group wonders what happened to Kenpachi and Yachiru, who still fail to find them.
