As the night settled over Osaka Castle, Anjin-Sama lay restless, dreams of a distant past lingering at the edge of his consciousness. Vague memories of battle and a shield that felt familiar yet elusive danced in his mind. Beside him, Mariko slept fitfully, unaware of the turmoil within Anjin-Sama's thoughts.

Suddenly, a strange sensation washed over him, jolting Anjin-Sama from his sleep. He sat up in bed, heart pounding, as a shimmering object materialized before him. It was a shield, a shield that seemed to glow with an otherworldly energy. Mariko stirred awake, her eyes wide with astonishment as she took in the sight before her. "Anjin-Sama... what is that?" she asked, her voice filled with wonder and confusion.

Anjin-Sama, his gaze fixed on the shield, felt a strange sense of recognition stirring within him. Without hesitation, he reached out and touched the shield, the moment his fingers made contact, a surge of power coursed through his body. Memories flooded Anjin-Sama's mind, images of battles fought long ago, a symbol emblazoned on the shield - a star with stripes. He remembered who he truly was - Steve Rogers, Captain America.

As Steve stood up, the shield firmly in his grasp, Mariko watched in astonishment as a transformation took place before her eyes. Anjin-Sama's body change. He grew taller, his muscles became larger. very well-defined.

"Anjin-Sama?" she asked.

Steve offered his hand to her and helped to her feet."My memories have returned. My real name is Steve Rogers. I've spent lifetimes fighting battles I can't even remember," he confessed. "But now, here with you, I feel like I've finally found a place to belong."

Suddenly, the peace of the night shattered as the sound of shurikens slicing through the air filled the room. The Ninjas, silent and deadly, had launched their attack on Osaka Castle.

Steve Rogers, now fully awakened to his true identity, stood ready with shield in hand. The air crackled with tension as the first wave of attackers emerged from the shadows, their weapons gleaming in the dim light. With a swift and precise motion, Steve deflected a flurry of shurikens with his shield, the metal ringing out like a bell as it repelled the deadly projectiles. The Ninjas, undeterred by the initial setback, closed in with astonishing speed, their movements like a deadly dance of death. The chamber echoed with the clash of metal against metal, the sound of combat filling the air. Steve's focus was unwavering, his mind clear and sharp as he engaged the attackers with a combination of skill and strength honed over years of battle.

"Get to safety!" Steve's voice rang out, commanding and resolute as he urged Mariko and the hostages towards the sturdy chamber with the solid door. He pushed them inside and closed the door after Mariko and turned to face the attackers headon.

Steve moved with practiced grace, his enhanced reflexes allowing him to anticipate their strikes before they even came. His shield became an extension of himself, a formidable barrier against the relentless assault. With each strike, he countered with a powerful blow, sending the Ninjas reeling. The chamber echoed with the clash of metal against metal, the sound of combat filling the air. Steve's focus was unwavering, his mind clear and sharp as he engaged the attackers with a combination of skill and strength honed over years of battle.

Steve's movements were a blur of motion as he fought with unmatched speed and agility. He moved with a fluidity that seemed almost unnatural, his shield becoming a deadly weapon in his hands. With each strike, he incapacitated his adversaries with a precision that left no room for error. The Ninjas, sensing the tide turning against them, redoubled their efforts, launching a coordinated attack from all sides. Steve remained undaunted, his resolve unwavering as he faced the onslaught head-on.

With a powerful thrust, Steve sent one Ninja flying across the chamber, his shield striking with a force that left a dent in the stone wall. Another attacker lunged forward, a katana flashing in the dim light, but Steve was ready. With a swift movement, he deflected the blade with his shield before delivering a devastating blow that sent the Ninja crashing to the ground. The chamber was now a battlefield, strewn with fallen foes as Steve stood amidst the chaos, his chest heaving with exertion. The last remaining Ninja, sensing defeat, hesitated for a moment before lunging forward with a desperate attack. Steve's response was swift and decisive. With a lightning-fast movement, he sidestepped the attack before delivering a powerful strike that sent the Ninja sprawling to the ground, defeated.

Silence descended upon the chamber as the last echoes of the battle faded away. Steve stood amidst the fallen, breathing heavily, with blood everywhere. Mariko emerged from the safety of the chamber, her eyes wide with awe and admiration.

"How... how did you do that?" Mariko asked, her voice barely a whisper, her eyes wide with wonder.
