You,Ichigo,Chad,Uryu,Orihime and Yoruichi (she's is in cat form for now) finally made it to the soul society but there was a barrier that prevents outsiders from breaking into Seireitei. So Yoruichi had a back up plan and lead y'all towards a weird looking building Yoruichi explains that Kūkaku has been known to change the location and design of her house without warning. While the actual design changes, the theme is consistent and the houses are recognizable from a single glance. Yoruichi notes that she prefers to live away from built up areas, where it is quieter.

You all enter into Kukaku's house and see Kūkaku smoking using a pipe. Her plan was to launch you guys using a huge cannon into the Seireitei but you first learn how to make a barrier with Kido so you don't crash and possibly die. she states that while she trusts Yoruichi, her trust does not extend to her companions. She therefore decides to send Ganju with them. You and Ganju started to fight which made Kukaku hit you both on the head

"Stop it right now both of you!" Kukaku said in a stern tone
