Takeda Shingen sat in the stands, his brow furrowed with frustration. He watched as Oda Nobunaga struggled against Mars, the Roman god of war. Despite Nobunaga's impressive strategies and resilience, Takeda could see the warlord's growing struggle under Mars's relentless onslaught. His memories drifted back to a time when he had faced Nobunaga in battle, a time when he himself had been brought to the brink by the man now fighting for humanity's survival.

"It was the Battle of Nagashino," Takeda began, his voice carrying to the other generals around him. "I had Nobunaga cornered. My cavalry, the finest in Japan, were about to overwhelm his forces. His arquebuses were formidable, but they could only do so much against our might."

Uesugi Kenshin, the Dragon of Echigo, listened intently, knowing the significance of Takeda's tale. "But something changed, didn't it?"

Takeda nodded, his eyes narrowing as he recalled the fateful moment. "Yes. Just when it seemed he was about to lose, something awakened inside him. He threw away his arquebuses and drew his katana. I remember the look in his eyes—fierce, unyielding. It was as if a sleeping dragon had awakened."

The battlefield of Nagashino was chaotic, filled with the sounds of clashing steel and the cries of men. Nobunaga stood amidst the turmoil, his forces wavering under Takeda's relentless assault. His arquebusiers had taken a toll on Takeda's cavalry, but it wasn't enough. The Tiger of Kai himself was pressing the attack, and defeat seemed imminent.

Nobunaga's mind raced, searching for a way to turn the tide. Then, in a moment of clarity, he made a decision. He discarded his firearms, gripping his katana with both hands. The weapon, dark and deadly, seemed to hum with energy as he focused his will.

Takeda's eyes widened in surprise as Nobunaga charged, his katana flashing in the sunlight. The warlord's movements were fluid and precise, each strike a masterful blend of power and skill. Nobunaga parried Takeda's attacks with ease, countering with deadly accuracy. It was a side of Nobunaga that Takeda had never seen, a testament to his true prowess as a swordsman.

The battle raged on, and Nobunaga's relentless assault began to turn the tide. Takeda, for all his might, found himself struggling to keep up. Nobunaga's blade was everywhere, parrying, countering, and striking with unerring precision. Takeda fell, a testament to Nobunaga's unyielding spirit and unmatched skill.

Back in the present, Takeda's voice was filled with a mix of pride and bitterness. "That day, Nobunaga showed his true colors. He was not just a strategist or a leader; he was an almighty swordsman. He parried and countered everything in sight, and I, the Tiger of Kai, fell to his blade."

Uesugi Kenshin nodded, his respect for Nobunaga evident. "He is a remarkable warrior. Let us see if he can bring that same ferocity against Mars."

On the battlefield of Olympus, Nobunaga faced Mars with the same calm determination he had shown against Takeda. Mars, sensing the need to end the battle swiftly, unleashed a devastating attack. His spear, glowing with divine energy, cut through the air, aimed directly at Nobunaga's heart.

To everyone's amazement, Nobunaga sheathed his dark katana and moved with lightning speed. With a swift, precise motion, he drew the blade and parried Mars's attack. The clash of metal against metal rang out, echoing through the arena. The force of the impact sent shockwaves through the ground, but Nobunaga stood firm, his eyes locked onto Mars's.

Mars roared in frustration, his attacks becoming more ferocious. He swung his spear in wide arcs, each strike capable of splitting mountains. Nobunaga met each blow with his katana, his movements a dance of lethal grace and precision. The warlord's swordsmanship was a sight to behold, a testament to years of relentless training and battlefield experience.

The gods watched in stunned silence as Nobunaga matched Mars blow for blow. Bellona's eyes widened with a mix of admiration and disbelief. "He is parrying Mars's attacks... how is this possible?"

Nobunaga's blade flashed in the dimming light, each strike aimed to exploit a weakness in Mars's defense. The Roman god, despite his overwhelming strength, found himself struggling to keep up with Nobunaga's relentless assault. The warlord's katana cut through the air with deadly precision, landing blows that began to take their toll on Mars.

Mars, for all his might and divine power, felt the strain of the battle. Nobunaga's calm demeanor only fueled his frustration. The warlord moved with a purpose, his every action a testament to human determination and resolve. Mars's strikes became more desperate, each one more powerful than the last, but Nobunaga met them all with unwavering resolve.

The arena shook with the force of their clash, the ground cracking and splintering under the pressure. Nobunaga's blade found its mark, cutting deep into Mars's flesh. Blood flowed, staining the ground beneath them. Yet, Nobunaga's expression remained stern and focused, his eyes never leaving his opponent.

Mars, exhausted and frustrated, fell to his knees, his spear slipping from his grasp. He looked up at Nobunaga, a mixture of respect and rage in his eyes. "You... you are formidable, mortal."

Nobunaga, his katana still poised, nodded slightly. "I fight for humanity. I fight for our survival."

The gods and humans watched in breathless anticipation, the outcome still uncertain. Mars's exhaustion was evident, but the battle was not over. Nobunaga's calm and relentless determination had brought him this far, but the final outcome was yet to be decided.

The clash of titans continued, each blow a testament to their respective strengths. Nobunaga, with his unmatched swordsmanship and unyielding spirit, faced Mars, the embodiment of war and divine power. The stage was set for a final, decisive clash, one that would determine the fate of humanity.
