Hey Cat-Scratch, the writer from Madoka is doing this. Kamen Rider Gaim, The Fruit Rider!
The Riders share the same type of belt, the Sengoku Driver and use various Lock Seeds in order to transform. The different Lock Seeds are based upon fruits. As Gaim is using the Orange Lock Seed, he can access the Orange Arms. While Baron uses the Banana Lock Seed, Baron can transform into Banana Arms. With the Lock Seeds, the Riders can perform different Arms Changes.
Kamen Rider Gaim is a story about an urban city which has rising with economic support from huge corporations, in particular Yggdrasil Corporation. While youth feel locked up and try to express themselves through dancing! These teenagers have been given Lock Seeds that allow them to summon small creatures called Inbes.
