Imprisonment?! Senbonzakura & Zabimaru

''' Imprisonment?! Senbonzakura & Zabimaru''' is the two hundred sixty-third episode of the Bleach anime.

Zabimaru and Senbonzakura become trapped in the Shinigami Research and Development Institute.

Summary
Several members of Division 6 are chasing a hammer carrying Tōjū through the streets of Seireitei. He loses them by ducking into a large urn, but Saru and Hebi spot him and manage to bring him down. While they are busy being praised by the Shinigami, the Tōjū recovers and traps them in a pile of dirt. The Tōjū defeats the Shinigami and is about to hit Zabimaru when Senbonzakura arrives and dispatches it, saving them.

A little later, fed up with being constantly compared to Senbonzakura, Zabimaru head off to deliver a broken Tōjū to the Shinigami Research and Development Institute, when Renji Abarai wants them to be writing apology letters for the damages they tend to cause. Upon arriving they find the place deserted, the entire staff having gone on a field trip. They manage to break inside by muscling the bars of a window open. Once inside they encounter Senbonzakura, also delivering a Tōjū that broke in through the door, leaving a gaping hole in it. The three walk together into the Tōjū confinement facility within the lab and find an empty container into which they insert the Tōjū brought by Zabimaru. Senbonzakura, however, begins to toy with the device's remote, which triggers the alarm and sets off a large fortified glass barricade dropping over them.

Senbonzakura attempts to break the case with his Shikai, but fails. Saru tells him they are just going to have to wait until the members of the 12th Division return. Senbonzakura agrees, but after several seconds loses his patience and begins to throw a fit inside the barricade. Saru and Hebi try to hold him back when a door opens and Ashisogi Jizō floats into the room. Senbonzakura and Zabimaru try to get him to set them free, but Ashisogi Jizō exerts too much power while pushing the button and breaks the remote. In his rage, Senbonzakura frightens Ashisogi Jizō away.

Senbonzakura, unable to stand the wait any longer, releases Bankai and breaks the barricade open, destroying the entire confinement area along with it. The security system meant to contain the Tōjū is triggered and the three have to outrun the closing doors, eventually arriving at a surveillance room through which the 12th Division monitors the private lives of everyone in Seireitei, like Izuru Kira using the urinal, Shūhei Hisagi and Kazeshini cooking, Marechiyo Ōmaeda and Gegetsuburi are grilling some food, Renji taking a bath, and Rangiku Matsumoto and Haineko running on the treadmill. Senbonzakura begins pressing buttons at random causing, minor disasters across Seireitei. While Senbonzakura argues with Saru, Ashisogi Jizō appears at the door in Bankai form.

Saru and Hebi retreat from Konjiki Ashisogi Jizō's path, but Senbonzakura stands his ground, saying he accepts the latter's challenge, he releases his own Bankai. Zabimaru, angered by Senbonzakura's irresponsible behavior, release their own Bankai and break up the fight between the two captain Bankais using Hikotsu Taihō. The attack misses Senbonzakura, who Shunpo away, but hits Ashisogi Jizō, effectively ending the fight. Unfortunately it also destroys the R&D Institution, and the entire affair is attributed to Zabimaru's recklessness when the entire Gotei 13 shows up. Upon thinking about it, Saru and Hebi realizes they have no evidence to back up their claim that Senbonzakura was the real culprit.

Enraged at what happened, Renji confines them to the barracks and assigns hundreds of apology forms for them to sign to keep them out of trouble, as Shunsui Kyōraku and Jūshirō Ukitake arrive with more forms. Saru and Hebi wonder how Senbonzakura can be so different from his master, but Shunsui and Jūshirō say he actually reflects Byakuya Kuchiki's true nature very well. When news arrive that Senbonzakura is leading the search after a new Tōjū, Zabimaru immediately set off to protect Seireitei from him despite their master's protest. Mayuri Kurotsuchi returns and is shocked to find the R&D Institution in ruins, as it shows Ashisogi Jizō still unconscious.
