Adolf woke up with a splitting headache. His vision was blurred, and his senses felt as though they were being rebooted one by one. The first thing he noticed was the luxurious canopy bed he lay on, its intricate carvings and silky drapes screaming aristocracy. The room itself was massive, adorned with gold-framed paintings, antique furniture, and a chandelier that sparkled like a cluster of stars.

"Where the hell am I?" he muttered, sitting up. His voice sounded unfamiliar, deeper, smoother.

A flash of memory struck him, and he froze. "Reincarnation?" The absurdity of the idea made him laugh nervously, but the recollection was too vivid to dismiss. It was true. He had died… and then somehow… come back. But not as himself.

He swung his legs off the bed and stumbled toward the ornate mirror across the room. The reflection that greeted him made him recoil in shock. Staring back at him was a young man with snow-white hair, piercing blue eyes, and a small, peculiar mustache that felt oddly… misplaced. He touched his face, running his fingers over the strange mustache.

"What the sigma is this?" he exclaimed.

Before he could process the situation, a robotic yet sultry voice echoed in his mind.

[DING! THE ULTIMATE RIZZLER SYSTEM IS BOUND!]

Adolf nearly fell backward. "What? A system?" he asked aloud.

The voice responded almost cheerfully. "Yes, Host! Congratulations on being chosen as the Ultimate Rizzler! Your mission is to bring chaos and charisma to this world by conquering the hearts of heroines and disrupting their destinies."

Adolf blinked. "Rizzler? Heroines? Disrupting destinies? You better start making sense before I lose it."

The system's tone didn't waver. "Host, your previous self may have been a nobody, but now you've been reborn as Adolf Rizzler, an aristocrat with extraordinary charisma. You've been granted the Ultimate Rizzler System, which will guide you in your quest to become the strongest Rizzler across dimensions."

Adolf pinched the bridge of his nose. "Okay, slow down. Let's start with why I look like this. White hair? Blue eyes? And this stupid mustache?"

"Your appearance is optimized for maximum Rizz energy," the system explained. "The mustache is a mark of distinction. You'll thank me later."

"I doubt that," Adolf muttered.

He glanced around the room, taking in the aristocratic décor. It was then that fragments of memories that weren't his own began to surface. This wasn't just his body—it was someone else's life. He remembered that the previous owner of this body had fled Germany for Tokyo, Japan, after being caught "rizzing" half of the beauties in his art school. The scandal had forced him to leave his comfortable life behind, and now here Adolf was, inheriting the consequences.

"Unbelievable," Adolf muttered, rubbing his temples. "So not only am I stuck with this weird system, but I'm also living someone else's messy life?"

As he tried to piece everything together, more names and faces surfaced in his mind. Familiar ones. He frowned, trying to focus.

"Wait a second," he said. "Rias Gremory? Seirenji Haruna? Yuki Mikan? Aren't these characters from anime?"

The system chimed in. "Correct! This world is a crossover of countless popular anime and manga universes. As the Ultimate Rizzler, it is your destiny to interact with and influence these worlds. Don't you want to rewrite the narratives and mess with the original protagonists?"

Adolf's jaw dropped. "You're kidding me. You're telling me I'm in some kind of anime mash-up world?"

"Exactly! For instance, your senior at the academy is none other than Rias Gremory, and you've already caught glimpses of characters like Seirenji Haruna, Yuki Mikan, and even Satoru Gojo, the strongest sorcerer alive."

Adolf's mind reeled. He did remember seeing someone with striking white hair and a blindfold when he arrived in Tokyo. At the time, he'd brushed it off as some eccentric rich guy, but now it all made sense.

"This is insane," he said. "Why me? Why did you pick me for this… Rizzler nonsense?"

The system's voice turned sly. "Don't play dumb, Host. Don't you want to mess up the original protagonists? Don't you want to see Issei Hyoudou, that perverted dragon, lose Rias's affection? Or watch Kazuya Kinoshita, that pathetic loser, crumble as you steal Chizuru Mizuhara from him?"

Adolf hesitated. The thought was tempting, though he hated to admit it. He'd seen those series, and frankly, some of the protagonists could use a little humbling.

"I'm listening," he said cautiously.

"That's the spirit!" the system chirped. "With your charisma and my guidance, you'll turn this world upside down. Your first task is simple: establish yourself in this society and start building your harem… I mean, connections."

Adolf sighed, dragging a hand down his face. "You're really not giving me much of a choice here, are you?"

"Nope!" the system replied cheerfully. "Now get out there and make the Edging Great Again!"

Adolf groaned. He had no idea what lay ahead, but one thing was certain—his life was never going to be the same.
