Villa
Clearing his flowers of icicles, the samurai returns home to his villa.
Picture the samurai's villa. It's in the countryside and covered in flowers and icicles. Even though it's spring, it's still cold, so all the new flowers are very cold.
そう, しょう, ちゃん
あごそ, ほうき
None
Once the samurai enters the villa, he lets his soul (そう) go. He's been fighting for long enough and this villa was always where he wanted to go.
Picture the samurai sitting in a chair in his beautiful villa and breathing his last breath. His soul slowly floats up and out of his still body and dances around the villa, free.
