Niwatori Fighter - Humanity is on the verge of collapse after the demonic Kaiju descend without warning, laying waste to cities and crushing all in their path. Resistance fails. Hope fades. Things look bad…until a lone rooster steps forward. Keiji, the neighborhood cock of the walk is more than just an ordinary rooster—he’s humanity’s greatest defender! His opponents may be ten stories tall, but
with razor-sharp spurs and a battle cry that splits the sky, this unlikely hero carries the fate of the world on his wings. When defenses fall and hope fades, one bird will rise.
