Tsai Tsusai

A young man who follows Maiko.
With well-proportioned appearance, he is always on guard.
Although there is something cold in his behaviour, he worries a lot about Maiko.
As he cannot speak or understand Japanese, he only speaks Chinese with Maiko.
There is a rumour about famous killer from Shanghai with the same name, but it is not clear whether or not he is the man from this rumour.
