The Bloodline System

Gustav Oslov was born into a world where a person's bloodline decides everything — their status, their future, and the respect they will ever receive. In an age when mixed-bloods channel superhuman feats through evolved bloodlines, his awakening was a public joke: the most useless evolved bloodline in recorded history, one that could do nothing but change the color of his hair. Overnight, the parents who had expected a prodigy began calling him useless trash. His younger brother, Endric, awakened a high-grade bloodline and took his place as the family's pride, while Gustav learned to survive on scraps of food and daily humiliation. The society of Plankton City made sure he knew, every single day, that people like him had no right to dream.

On the night he climbed to the edge of a cliff to end his life, something answered from the sky. A crimson star tore out of the heavens and slammed into the mountainside, and a small glowing fragment found its way into Gustav's mouth. When he woke, a cold, sarcastic voice was counting down in his head — accept the power or die. He accepted.

That was the day the Bloodline System chose him.

The system is unlike anything the world has seen. It evolves his body, grades his progress, and hands him an ability that should not exist: the power to acquire the bloodlines of others — beast or man — and make their strengths his own. Where every citizen is locked into the bloodline they were born with, Gustav can collect them all, one extraction at a time, and the system is only beginning to reveal what it can truly do. But power drawn from others must stay hidden. If the wrong people discovered how his strength keeps growing, it would be treated as a catastrophe — or hunted as a prize.

Guided by Miss Aimee, a grey-haired teacher with secrets of her own who becomes his mentor, and pushed forward by Angy, the horned girl next door whose kindness survived the same world that discarded him, Gustav rebuilds himself from the bottom. He takes odd jobs from Boss Danzo to fund his training, brawls his way through Echelon Academy where the strong prey on the weak, and steps into the tournaments and exchange events where prodigies like his brother are celebrated. Every battle sharpens him. Every bloodline he absorbs awakens something new. And every step upward drags the attention of rival prodigies, shadowy forces that want his power for themselves, and an MBO officer who starts to wonder why the name Gustav Crimson feels so familiar — and why a nobody from the Oslov family reads like anything but a nobody.

This is the story of a boy the world threw away, armed with the one power nobody can see coming. To climb from trash to the top of a bloodline-obsessed civilization, stolen abilities alone will not be enough. He will need the nerve to walk into the federation's trials, the wits to guard his secret, and the will to stand at the very top of a world that never believed in him — starting with an entrance test only the strongest mixed-bloods survive.
