The morning air was crisp in Pallet Town. Ash had recently claimed victory over Leon, becoming the Monarch in the thrilling final round of the Master 8 tournament. Now, Ash and Pikachu savored a peaceful moment in the Ketchum residence when an unexpected knock shattered the tranquility.

Approaching cautiously with Pikachu on his shoulder, Ash peered through the peephole to spot two sharply dressed men in black suits standing at his doorstep, their serious demeanor almost imposing. Ash hesitated before opening the door.

"Good morning, may I help you?" Ash inquired politely, curiosity piqued.

The taller man stepped forward. "Good morning, Monarch. We represent the Mishima Zaibatsu."

Ash's brow furrowed. "The Mishima Zaibatsu? I've never heard of it... What brings you here?"

The man explained, his tone practiced. "We're here on urgent business regarding the passing of Heihachi Mishima, the former head of our organization."

Ash was perplexed. "I'm sorry, I don't understand..."

"Our investigation has revealed a surprising connection between you and Heihachi Mishima," the other man continued.

"A connection?" Ash echoed, now fully captured.

"Yes," the first man nodded. "It appears Heihachi Mishima had a relationship with a woman named Delia, and you are a descendant of that union."

Ash's eyes widened. Delia – his mother's name. Could this be true? He had never known his biological father and had grown up under the care of his childhood idol, Professor Oak. The notion of being linked to the powerful Mishima family was both startling and bewildering.

"In Heihachi's will, he rejected naming his son Kazuya Mishima as his heir. Consequently, our organization has been seeking an alternative successor, and you, Ash, are a rightful candidate due to your familial ties," the man explained.

"But why me? I just want to focus on becoming the greatest Pokémon Master," Ash replied, his mind racing with questions.

"Heihachi's will stipulated that anyone carrying the Mishima bloodline and deemed worthy could inherit the title. You, Ash 'Mishima', fit that criterion," the second man added.

Ash tried to process the gravity of the situation. In an instant, his life seemed to be veering down an unexpected path. Before he could speak, the taller man snapped his fingers.

Suddenly, Ash's home was filled with heavy footsteps and shouting. Ash and Pikachu tensed, unsure of what was happening. Tekken Force soldiers burst through doors and windows, swiftly securing the premises.

Ash's heart raced as he looked around in alarm.

Pikachu was ready to protect his Trainer.

"All hail Ash Mishima!" the soldiers proclaimed as they surrounded him.

Ash was dumbfounded. Why were these soldiers pledging allegiance to him? How could he, a Pokémon Trainer, be thrust into the world of corporate power and intrigue?

"I'm so lost..."
