Haruto Hayase was a normal high school boy in his third year, living a quiet life until his younger sister, Haruka Hayase, joined the same school. Haruka’s beauty and charm made her the center of attention, quickly becoming the school’s prima donna. But when a notorious gang leader set his sights on her, he did everything in his power to protect her—only to fail tragically. Haruka was brutally assaulted and tortured, and Haruto himself suffered an agonizing death. However, in a twist of fate, Haruto is given a second chance, waking up a year before the events that shattered his life. Armed with the mysterious ‘Debauchery System Slave’, he vows to exact revenge on those responsible. This time, he will use his newfound powers of the system and charm to seduce the loved ones of his enemies. From their mothers, sisters, and lovers to their closest friends, Haruto will make them his. His enemies will suffer as he steals what they hold dearest, ensuring their downfall in the most devastating way possible.

SSS Beast Apostle System and Survival Racing in Apocalypse.

When the aliens invaded earth, they didn’t come for its resources as many doomsayers had proclaimed throughout the years.

Instead, they came for fun.

They came, flattened earth’s biggest cities and turned the world into a planet-sized stadium for their civilization.

The sport?

Survival Racing.

Ferocious alien beasts were unleashed upon the ruins of the world along with thousands of alien death-row fugitives who were only told one thing: Kill the humans, survive the year and regain your freedom.

Elliot was a survivor. He died right before he entered the final 15 days of the Games.

But as his consciousness began to slip away, a metallic voice rang out within his soul.

Mission failed.

Activating sponsor's Boon: Beast System.

Welcome to the Beast System. My name is Hawk, your AI.

EXCERPT from Chapter 1:

Elliot screamed in absolute exhilaration as he smashed his foot on the brakes, just enough to fully utilize the power of his ceramic brakes but not so much that his tires locked up. He went from two hundred miles an hour to forty miles an hour in a heartbeat.

He entered the sharp corner from the outside at the maximum entry speed and skillfully brought his car to the threshold of his tire’s grip.

SCREEE!!

He took the corner at record speed like a professional racer and then floored the pedal to the metal once more!
