The Royal Guard Arrive

Prologue
After laying waste to Soul Society, Yhwach retreats, stating that the Royal Guard will likely show up now. . As the medical units treat the injured, Ichigo Kurosaki is called to Captain Mayuri Kurotsuchi's office to try to repair his broken Zanpakutō. Once there, Mayuri informs Ichigo that he cannot repair the sword as a Bankai cannot be repaired. As he is told this, Ichigo is bombarded by Kon, who has a new buff body. Ichigo does not initially recognize him, causing Kon to try to show off. Meanwhile, Mayuri receives notice that he is needed elsewhere and tells Ichigo to come as the Royal Guard will be arriving. Elsewhere in Seireitei, the other captains have begun to gather outside the walls of Seireitei. Upon arriving, Ichigo calls out to Captain Shinji Hirako. Shinji questions if Ichigo is there to watch the Royal Guard arrive, but says that he does not recommend it. Ichigo begins to ask several questions, asking why they have not shown up already and where they normally live. Captain Shunsui Kyōraku interjects, stating that they live in the Soul King Palace. Ichigo asks where the Soul King Palace is and if it is not in Soul Society. Shunsui tells Ichigo to think back to when he first arrived in Soul Society and how the walls fell from the sky. He states that the walls normally only protect Seireitei in times of emergency but lately have been down all the time due to harsh times. He then asks if the walls are only there during emergencies, what do they normally protect. Before Ichigo can speak, he states to look up, saying that they are here. A large pillar then falls from the sky, landing right before the gathered. Ichigo wonders what it is, to which Shunsui replies that it is their preferred means of travel, the Tenchūren. He says that all the members of the Royal Guard are inside, which makes Ichigo wonder how they can all fit inside as it is so small. As the pillar begins to open, Shunsui states that there are no foot soldiers in the Royal Guard. There are only five members, all of them former captains and their combined power is greater than the combined power of the entire Gotei 13. As he says so, the Royal Guard step out.
