Description

A 2013 April Fool's game.

When the 14-years-old protagonist's (Nike) father and mother died, she was taken over by her uncle, Rijurel, who is of a blood-sucking species. She is a bit scared of him, but Rijurel is her only family now. He had hired Nike a butler to look after her. His name is Yuwen and he's of serpent species...

It should be noted that Nike resembles a canary (with her wings, timid personality, her stature and haircut), so the title is actually referring to her. If you add this up to the this novel's plot, you will get a canary, trapped in a castle for a cage, with two "predators": her bloodsucking uncle and serpent butler.
