A rooster the size of a man fights kaiju with nothing but his crow and his conviction. The joke never gets old because the show doesn't bother explaining it, it just escalates, treating a tiny bird's impossible heroism with the same orchestral weight as actual giant monster movies. Keiji screaming Kokekokko while delivering a flying kick to something twenty stories tall is the entire point, and the soundtrack knows it.

Keiji is a rooster with an unlikely calling: protecting humanity from the towering kaiju that have suddenly descended and are wrecking cities. As human resistance fails and hope fades, this neighborhood cock of the walk steps forward as the world's greatest defender. His foes may stand ten stories tall, but he meets them with sharp spurs, a big heart and a fearsome battle cry. Rooster Fighter mixes action, adventure and comedy with a supernatural edge, built on the absurd sight of one bird carrying the fate of the world on his wings.
