Eh close enough, welcome back Kamen Rider Blade.

Probably not a coincidence, is the thing. Takara is known for very blatantly taking inspiration from other popular works. The Brave series was inspired by Transformers, Zoids was inspired by Gundam, and now we have Ryukendo, which is very much taking notes from other Toku, Kamen Rider especially.
