A New Enemy! The True Nature of the Beast Swords

'''A New Enemy! The True Nature of the Beast Swords''' is the two hundred and fifty-seventh episode of the Bleach anime.

Hitsugaya defeats a Tōjū that has been absorbed by a Hollow.

Summary
An unnamed Tōjū goes to the Human World to look for his master. Ichigo has a short run in with him, but the Tōjū escapes. The 10th Division Captain and lieutenant, Tōshirō Hitsugaya and Rangiku Matsumoto follow him there, accompanied by their respective Zanpakutō, Haineko and Hyōrinmaru. Hitsugaya fills in Ichigo and Urahara about the current situation in Soul Society.

The Tōjū is absorbed by a Hollow and the two fuse together, forming a Zanpakutō/Hollow hybrid. Ichigo battles the creature but is thrown back by a powerful Cero before he can use Getsuga Tenshō. Hitsugaya dispatches it easily by releasing Hyōrinmaru, causing the Tōjū's released Zanpakutō, a spear-like weapon, to break.
