Once upon a time, there was a true story that happened about 600 years ago. It's a story of a very beautiful girl who lived in a country that no longer exists.

Suicide-Master, who woke up from starvation, was told by Tropicalesque that the cause of her death was "the Beautiful Princess." Intrigued by her tale, Suicide-Master goes out to find "the Beautiful Princess" to have her as a first meal out from her slumber despite Tropicalesque's warning.

Suicide-Master, who still keeps dying, realizes that consciousness reform is needed for both the one who eats and the one who gets eaten. She watches Princess Acerola try her best to change with a smile, but Tropicalesque has a thought for his master.
