The Bira Bira no Mi is a Paramecia-type Devil Fruit that allows the consumer to create flower petals.
Strengths and Weaknesses
The user can use the flower petals to put people to sleep, poison people, paralyze people, and can be adjusted to be as soft or sharp as necessary.
The main weakness of the fruit would be fire or intense heat, which would simply cause the petals to burst into flames. If the user could produce a strong wind, they would also be able to blow the petals away and render them harmless. The standard Devil Fruit weakness also applies.
