Ayakashi Saigyou is a youkai cherry blossom tree, and is the largest cherry blossom in the gardens of Hakugyokurou. Not much is known about the tree, but it has existed in the Netherworld longer than the Ghost Princess, Yuyuko Saigyouji, herself. There seems to be a powerful seal within Ayakashi Saigyou which drains most of its energy away, leaving it unable to blossom well during spring. Whether the tree is sealing something, or whether the tree itself is being sealed, remains a mystery.
Of course, once Yuyuko's story gets translated, more information should be added here.
