Niwatori Fighter

Giant monsters descend on cities that ordinary defenses cannot protect, and into that hopeless situation steps the most unlikely champion imaginable: a rooster named Keiji. He has no advanced weapon or army, yet he confronts creatures dozens of times his size with claws, a deafening crow, and a stubborn refusal to let innocent people die in front of him.

Keiji travels from place to place searching for the monster that changed his life, meeting humans and animals who leave their mark on him as he changes theirs. Beneath the absurd image of a rooster hero lies a sincere journey about courage, loss, and choosing to fight even when victory seems ridiculous.
