The Power of Madam Butterfly - a special edition

Madame Butterfly was one of the heroes who defended Paris, but during that time she had never used her special power until this moment. But is her power so special that she has to hide it or is there something else she doesn't want anyone to know about. This story is related to the story"Miracouls:Owl and butterfly"but can be read as a standalone story, but I recommend you read it.
