Rebirth of the Supreme Celestial Being - Chapter 689 - Who are you?

“Primum non nocere.”

In a future timeline, the earth was visited by a species known as the Slarkovs.
Having lost their home planet and in search of a new one, earth was the next habitable planet for them.

Humans and Slarkovs made a deal with each other in return for the Slarkovs living on earth.
The Slarkovs traded their technology and knowledge for a new home.
They were similar to humans except for some of them who had slight differences so fitting into the society wasn't a problem.
Over the years Slarkovs and humans began to mate with one another and reproduce offsprings.
This in turn created a new species known as the mixed-blood.
Centuries later mixedbloods could tap into their bloodline and perform unimaginable feats.

Gustav born into an age where bloodline determines everything, struggles to fit with a useless bloodline.
His bloodline only grants him the ability to change his hair color, destroying his hopes and dreams for a great future.
His fate is turned around when an unexpected situation leads to him finding a system that grants him the power to unlock and upgrade bloodlines by completing quests but he's baffled by two quests with a five-year deadline. Success will grant him unimaginable rewards...
But only one thing awaits him if he fails... Death!

Follow Gustav on his interesting journey filled with unprecedented adventures, danger and death, maybe?

In the Central 46 Compound, the Captain-Commander of the Gotei 13 and the notorious scourge of the Female Shinigami Association, Masatsuki Aozaki, stood before the Sages and Judges.“You have improper relationships with numerous members, Seated Officers, and Captains of the Seireitei?”“As Captain-Commander, maintaining close relationships with them helps facilitate my work.”“...”The Judge narrowed his eyes. “Then how do you explain modifying the female Shinigami's Shihakushō into miniskirts?”“To transform the Seireitei into a perfect paradise.”“Tsk tsk… A paradise for all Shinigami? That’s not entirely unreasonable…”“No, a personal paradise.”“A private—wait! Captain-Commander Masatsuki, that kind of thinking is clearly wrong!”“Do you want to die?”“...”“Forget it, Captain-Commander Masatsuki. We’ll set this matter aside for now. Let’s discuss some of the outrageous statements you’ve made in the past. Those were jokes, right?”“No, I was completely serious.”Masatsuki calmly ran his hand along the hilt of his Zanpakutō and spoke with conviction. “I have a great relationship with my subordinates, I get along well with Hueco Mundo, and I’m even friends with all of your wives and girlfriends. But rest assured, I’m a good Shinigami. You can safely leave the world in my hands!”Genryūsai Shigekuni Yamamoto: That damn brat! Shunsui, Jūshirō, don’t stop me—I need to teach him a lesson!Thus begins the tale of the most incorrigible Shinigami!
