Summary
Jin Kariya’s underlings force open the North and West gates into Seireitei by using the giant wooden siege machines that they had built. They are immediately confronted by a small Shinigami force, but Kariya strides to the front of the pack and blows them all away with his wind power. However, he also turns his powers against his own non-Bount allies and disposes of them because he no longer needs them as pawns to open the gate. Ichigo Kurosaki and company arrive on the scene soon after and find Jidanbō Ikkanzaka lying on the ground. Kariya notices them and destroys the siege machine that is keeping the gate propped up, closing the gate again. He wants Yoshi and Mabashi to create a distraction while Sawatari and Gō Koga go after captains. Kariya heads to the Shinigami Research and Development Institute.

Outside the gate, Orihime Inoue heals Jidanbō, until he is able to get up again. The giant lifts up the gate with brute force, allowing everyone through. Inoue, however, decides not to go with them and instead stays outside to heal Jidanbō. After the group separates to find the Bount, Rangiku Matsumoto and Tōshirō Hitsugaya are visited by a Hell Butterfly calling for a captain’s meeting. Soifon also receives this message and sends her troops out to search while she is away. Those soldiers come across Mabashi, who summons and multiplies his doll, beats the men up, and runs away as part of his strategy. In the captains’ meeting, Mayuri Kurotsuchi accuses Hitsugaya of not doing his job and letting the intruders through. Hitsugaya takes responsibility, but Shunsui Kyōraku is a lot more forgiving than Mayuri is. The Eighth Division captain turns the tables on Mayuri by raising the subject of the Quincy item that let the Bount come to Soul Society. Yamamoto orders them to go out and exterminate the Bount. Each division is going to operate independently and Hitsugaya is now dismissed as the commander of this operation.

Ririn, Kurōdo, and Noba meanwhile sense the Bount’s spiritual power going on and off around Seireitei, giving them a hard time tracking the enemy down. When another Shinigami force comes across Mabashi, he uses his doll Rizu to stab and defeat all of them. The battle lasts only a few seconds and Mabashi moves on to the next group of Shinigami. At the Second Division, Soifon decides to regroup her troops and gets reports from all of them. After giving out new orders, she starts to walk away, but is suddenly hit by a dart. The others troops quickly restrain the culprit, who is someone who had fought Mabashi earlier and had gotten taken over by Rizu. However, the damage has been done, and now Soifon has been weakened by whatever was in the dart.
