Kamen Rider Kuuga

A multi-taleted man named Godai Yusuke gains the power of the ancient warrior “Kuuga”, and with the help of officer Ichijo Kaoru, fights the murderous monsters known as the Grongi, in order to save humanity.
However, things start to turn twisted when another Kuuga-like entity appears, and the police decide to build their own anti-Grongi suit.
