The Sealed Sword Frenzy

The Sealed Sword Frenzy was the second OVA. It was featured in the Bleach Jump Festa 2005 Anime Tour. It appears to take place soon after the Soul Society arc.

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

At Urahara's Shop, he reveals that the being is a Zanpakutō-lacking Shinigami named Baishin, who terrorized Soul Society until they sealed him away forever...or so it seemed. At which point, Soul Society members arrive to take action (excluding Kenpachi and Yachiru due to navigational problems). The group splits up around the city to take on Hollows summoned by Baishin. Ichigo, Rukia, and Renji arrive at the ruins to find Baishin, who drains Ichigo's spirit energy to the point of passing out. When Baishin attempts 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 attempts 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 consciousness and proves more formidable. At the climax of the fight, Ichigo enters his bankai and easily overpowers and bifurcates 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 brief sympathy for Baishin, the group wonders what happened to Kenpachi and Yachiru, who still fail to find them. At the end it shows Kenpachi and Yachiru chasing a bullet train, they eventually end up vacationing on it. Every other Shinigami ends up spending time in the real world, with mixed results. For example; Hitsuyaga is stuck in a student uniform, Byakuya appearing in a carriage wearing 18th century clothing (much to Renji's and Ichigo's chargin), and Yoruichi and Urahara going on a date (causing Soifon to become utterly enraged). Gin Ichimaru, Kaname Tōsen, and Sōsuke Aizen also appear at the very end (wearing modern clothing), with Gin telling the audience to "be careful on the way home".
