**A Blow to the Unbeatable**

The air was electric with tension as the two men sized each other up, waiting for the other to make the first move. It was clear that this was more than just a casual encounter - this was a battle of wits, strength, and pride. And only one man would emerge victorious. Without warning, Osamu Dazai lunged at Shizuo, his movements lightning-fast and fluid. Shizuo, confident in his own abilities, charged forward to meet him. The two men clashed in a blur of fists and feet, their punches and kicks flying in every direction. At first, it seemed like a closely matched fight, with both men exchanging blows and neither gaining the upper hand. But as the fight wore on, it became clear that Osamu Dazai was not to be underestimated. He dodged and weaved around Shizuo's attacks with ease, landing precise and powerful blows that sent Shizuo stumbling back. Shizuo's eyes widened in shock as he realized he was actually being pushed back. He had never lost a fight before, and the feeling was unbearable. He gritted his teeth and launched himself at Osamu Dazai, determined to turn the tide of the battle. But it was too late. Osamu Dazai landed a devastating kick that sent Shizuo crashing to the ground. Shizuo struggled to get to his feet, but Osamu Dazai was too quick. He pinned Shizuo to the ground, his knee pressed into Shizuo's chest. As Shizuo looked up at Osamu Dazai, he felt a wave of fear wash over him. He had never felt this way before. "Who the hell are you!" Shizuo shouted, trying to hide the fear in his voice. Osamu Dazai grinned, his eyes glinting with amusement. "Ah, I'm Osamu Dazai, from the Port Mafia. And you, my dear Shizuo, are now my prize." Shizuo's eyes narrowed, trying to process what was happening. He, the strongest man in Ikebukuro, had just been defeated. It was unthinkable. "Now can I receive my prize?" Osamu Dazai said happily, grabbing Shizuo's chin. Shizuo tried to back away, but Osamu Dazai's grip was like a vice. "What do you want?" Shizuo demanded, trying to keep his voice steady. Osamu Dazai's grin grew wider. "Shizuo, I want to marry you." Shizuo's eyes went wide in shock. "Marry me? Are you crazy?" Osamu Dazai chuckled, his eyes sparkling with mirth. "Oh, I'm completely sane, I assure you. And I've never been more serious in my life. You see, I've always been drawn to strong men, and you're the strongest of them all. I just can't let you go." Shizuo's face twisted in disgust. "You're... you're unbelievable. I don't do that sort of thing." Osamu Dazai's expression turned mock-serious. "Oh, come now, Shizuo. Don't be coy. I know you're intrigued. And I promise you, I can be a very... persuasive partner." Shizuo struggled against Osamu Dazai's grip, but it was no use. He was trapped, and he knew it. For the first time in his life, he felt truly vulnerable. And it was a terrifying feeling.
