Victor Ken's life was, to put it mildly, a spectacularly depressing affair.
For twenty-two years, he had been the invisible man. He had never held a girl's hand, never received a Valentine's Day chocolate that wasn't out of sheer, agonizing pity from his own grandmother, and ultimately, never experienced an ounce of romantic love. His sole refuge was the world of anime, manga, and light novels—specifically, the ones featuring intensely obsessive, wonderfully unhinged women. Yanderes were his gospel.
His death, fittingly, was a tragicomedy. He wasn't hit by the legendary truck. No, Victor was crushed by a poorly secured, two-ton promotional billboard of his favorite crimson-eyed anime villainess while walking home from a convention. As his ribs collapsed and his vision faded to black, his final, pathetic thought was: At least she's the one stepping on me.
Then, the darkness shattered.
Victor gasped, his lungs inflating with air that tasted strangely like ozone and crushed roses. He jolted upright, clutching a chest that was completely intact. He wasn't on the blood-stained pavement of a city street. He was sitting in a bed large enough to sleep a family of six, draped in silk sheets the color of midnight.
"Where...?" His voice sounded different. Deeper, smoother. Resonant.
Memories that did not belong to him suddenly hammered into his skull like a runaway freight train. He groaned, gripping his head as a lifetime of foreign experiences flooded his consciousness.
Vampires ruling the western aristocratic courts. Dragons nesting in the jagged peaks of the Dragontooth mountain range. Elves and dark elves locked in a perpetual, bloody cold war in the Great Forests. Mermaids drowning sailors in the Abyssal Sea. Demons lurking in the shadows of society.
And amidst it all, him. Kaiser Warborn.
He was no longer Victor Ken. He was Kaiser, the seventeen-year-old step-son of Isolde Warborn, the legendary "Blood Iron Duchess" and arguably the strongest, most terrifying woman in the Vesperian Empire. He also had a step-sister, Seraphina, who was a prodigious knight in training. Kaiser, on the other hand, was known as the Duchess's weakest link—a boy brought into the family through a political marriage, possessing frail health and mediocre magic.
Swinging his legs over the edge of the bed, Kaiser staggered toward a massive, ornate silver mirror resting in the corner of the gothic bedroom.
He froze.
The reflection staring back at him was absurd. The guy in the mirror had a face sculpted by the gods themselves—an absolute 10/10 masterpiece of sharp jawlines, aristocratic cheekbones, and flawless pale skin. But what caught his attention wasn't just the sheer, unfair handsomeness.
It was the hair. A cascading mane of pure, luminescent white that fell to his shoulders. And his eyes—they weren't normal. They were twin pools of endless, pitch-black void, completely devoid of irises or sclera. They looked demonic.
"Okay, so I'm gorgeous, but I look like I eat souls for breakfast," Kaiser muttered. As soon as the thought crossed his mind to look less conspicuous, a warm sensation rippled through his face. In the mirror, the pitch-black void bled away, replaced by a stunning, deep sapphire blue. His pure white hair shortened and darkened into an elegant raven black.
He could disguise his true appearance at will. Handy. He willed his true white-haired, black-eyed form back, preferring the intimidating aesthetic in the privacy of his room.
Suddenly, a translucent blue screen materialized in the air in front of his face, accompanied by a sharp DING!
[SYSTEM INITIALIZATION COMPLETE.]
[Welcome, Host. The Seducing Survival Odyssey System is now online.]
"A system?" Kaiser's eyes widened. His otaku heart leaped into his throat. "Wait, seducing survival?"
[Current Status: Weak. Physical attributes are below average. Magic capacity is unrefined.]
[Primary Directive: Survive and Conquer.]
[Rule 1: The Host will encounter specific 'Targets'. The more the Host interacts emotionally and physically with the Targets, the more their Affection will grow.]
[Rule 2: Affection Milestones]
0%: Stranger / Indifferent
30% - 40%: Friends / Allies
80% - 99%: Deep Romantic Love
100%+: Absolute Obsession / Yandere Awakening
[Rule 3: Failure to successfully raise the affection of designated Targets within given time limits will result in the ultimate penalty: INSTANT DEATH.]
Kaiser stared at the floating blue text. Most people would have panicked at the words 'Instant Death'. Most people would have been horrified by the 'Yandere Awakening' at 100%.
Kaiser, however, slowly formed a wide, unhinged grin.
Obsessive, crazy girls? A world of magic? A face that could make angels weep?
"Oh, I am going to abuse the absolute hell out of this," he whispered, a giddy laugh escaping his lips. "If I have to romance a bunch of terrifying, powerful women to survive... don't threaten me with a good time."
But reality quickly set in. He was currently weak. A handsome face wouldn't save him if a werewolf decided to rip his throat out, or if he failed to charm a dragon before it roasted him. He needed power. He needed to grow.
According to Kaiser's inherited memories, the Zenith Grand Academy was the premier institution for magic and combat in the world. Only the elite, the monstrously talented, or the obscenely wealthy were admitted. If he wanted to survive the System's deadly ultimatums and stand beside—or above—these future targets, he couldn't rely on the Duchess's name. He had to enroll based on his own pure talent.
BAM!
The heavy oak doors of his bedroom were violently kicked open, slamming against the stone walls with a deafening crack.
Kaiser jumped, his heart skipping a beat as he hurriedly willed his raven-hair and blue-eye disguise back into place.
Standing in the doorway was a girl radiating pure, condensed violence. She had cascading crimson hair, piercing golden eyes, and wore a form-fitting training uniform that accentuated a figure that would make goddesses envious. She held a training sword slung over her shoulder, glaring at him with a mixture of annoyance and disgust.
This was Seraphina Warborn. His step-sister.
[TARGET ACQUIRED: Seraphina Warborn]
[Current Affection: -15% (She thinks you are a lazy parasite dragging down the family name.)]
[Warning: Host's life is not in immediate danger, but a stray training blow could cause severe internal bleeding.]
"You're awake," Seraphina spat, her voice dripping with venom. "I told Mother letting you sleep until noon was a mistake. We have a family name to uphold, Kaiser, and your pathetic frailty is an embarrassment."
Kaiser blinked. A negative fifteen percent affection rating? That was actually impressive.
Instead of cowering like the old Kaiser would have, he leaned against the heavy bedpost, crossing his arms and flashing her a devastatingly charming, slightly lazy smile.
"Good morning to you too, dear sister," Kaiser drawled, thoroughly enjoying the sudden, brief look of confusion that crossed her face at his lack of fear. "Though, considering how hard you kicked that door, I'd say your footwork is a little heavy today. Are you overcompensating for something?"
Seraphina's golden eyes widened in sheer disbelief. The 'parasite' was talking back? And analyzing her footwork?
"What did you just say to me?" she growled, stepping into the room, her aura flaring with heat.
"I said," Kaiser pushed off the bed, walking slowly toward her until he was just a few feet away, entirely unafraid of the glaring step-sister who could snap him like a twig. "That I'm done being the weak link. I'm taking the entrance exam for the Zenith Grand Academy in two months."
The room went dead silent. Seraphina stared at him, then let out a sharp, mocking bark of laughter.
"You? The Grand Academy? You can barely conjure a spark without passing out, Kaiser. You'll die in the preliminary trials."
"Care to make a bet, then?" Kaiser leaned in closer, dropping his voice to a smooth, confident whisper. The scent of sweat and steel radiated off her. "If I fail, I'll formally renounce my ties to the Warborn family. I'll pack my bags and disappear. You'll never have to look at my 'embarrassing' face again."
Seraphina's mocking smile vanished, replaced by a suspicious scowl. She scrutinized his face, looking for the lie, but only found absolute, unnerving confidence in his sapphire blue eyes.
"And if you somehow miraculously pass?" she challenged.
Kaiser smiled, a genuine, slightly wicked grin. "If I pass by my own merit, you have to acknowledge me as your equal. And... you have to grant me one favor. Anything I want."
[Target: Seraphina Warborn. Emotion detected: Intrigue. Anger.]
[Affection updated: -10%.]
Progress, Kaiser thought smugly.
"Fine," Seraphina sneered, turning on her heel. "Have it your way, parasite. Don't come crying to me when they mop you off the arena floor. Training starts in ten minutes. If you're late, I'll use you as a practice dummy."
As she marched down the hallway, Kaiser let out a long breath, a bead of sweat rolling down his temple. She was terrifying.
And he was absolutely thrilled.
"System," Kaiser muttered, summoning a small orb of basic mana into the palm of his hand, watching it flicker. It was weak, pitifully small. But the System had integrated with his soul. He could feel the potential locked within him, waiting to be unleashed. "Show me the skill trees. It's time to grind."
The survival odyssey of the world's most handsome, yandere-loving otaku had officially begun.
