Experimental: サウロンの新しい同盟者

Encouraged by Commander Kamen Rider Chrome, my feeble attempt to make a tiny tribute to his epic "Kamen Rider Days" facfiction series. Set after KAMEN RIDER DAYS IV: ETERNAL DARKNESS, what if Sauron figures out how to get things done correctly, and starts over again with an unlikely ally? Again, special thanks to Commander Kamen Rider Chrome.
