Summoners War: Only I Summoned Divine Beasts

In a world where summoners command the power to call forth vampires, elves, angels, demons, and all manner of humanoid creatures from across the realms, Nathan found himself uniquely limited to summoning only beasts. Yet, these were no ordinary beasts. They were divine entities that once rivaled, or even surpassed, the legendary creatures the world had ever known. Casting his gaze to the left, Nathan sees numerous summoners flanked by demon kings, archangels, vampire progenitors, and other legendary beings. Turning to the right, a massive army of alien symbiotes is poised to attack. There was no fear in his eyes, for standing on his left is a majestic wolf who once slew a god, the legendary eight-headed serpent coils on his right, above him soars a bird glowing like the sun, and behind him looms a dragon that once gnawed at the roots of the world tree. "Let the war begin."
