While walking down a certain forest in the outskirts of the Rokun Distirct, Captain Commander Yamamoto stumbled upon a peculiar sakura tree. Why peculiar? Because the flowers it bear are all turned to ice.
At the foot of the tree, a girl in white tattered clothes lay sleeping peacefully. What caught the captain's eyes is the butterfly clip she has on her hair and the ears and tails of a cat she has.
Thinking that she is an abandoned girl, Captain Commander Yamamoto decided to bring her back to Seiretei and tend to her.
Will this girl bring joy to the Gotei 13? And what about the massive amount of reatsu she is suppressing inside her?
