Kuchiki manor

The biggest, richest and most luxurious estate in Soul Society. As the Kuchiki are one of the Four Noble Families (and consider themselves the most noble of them), they have to show off their wealth, good taste and general noble-ness. Nobles tend to be like this, but the Kuchiki even more so. Because they are the noblest of all nobles. Their manor is something to marvel at. It has stylish buildings, large gardens full of koi ponds (though their fish have been disappearing lately) and cherry blossom trees and the headquarters of the SWA. That isn't approved by the current head of the family, but it's very hard to make Kusajishi Yachiru leave. The Kuchiki manor is a place worth seeing, but be sure to obtain an invitation. If you come uninvited, you'd be escorted out by dozens of pink and purple clad ninja. If you came with an invitation, you'll get to see Kuchiki Byakuya's collection of Wakame Ambassadors and Kuchiki Rukia's collection of Chappy.
