High School DxD - Volume 24 Chapter 1

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?

Eric Langley, an eighteen-year-old boy whose parents passed away three years ago, had no known relatives and was left to fend for himself. To support himself, he worked in a bakery, using his earnings to cover his daily needs and indulge in his favorite pastime—reading chapters of the novel “Humanity's Strongest Mage,” which had recently gone on hiatus.Eric had a love-hate relationship with the novel. While he was captivated by its world, he despised the Protagonist, Alex Whiteheart. Alex had it all from the start: strength, fame, money, and of course, a harem. He never faced any real challenges, effortlessly overcoming every obstacle, which made the story lack something Eric craved....... Chaos.One evening, while taking a walk with his headphones on, Eric was lost in thought. The music drowned out the world around him, and he failed to notice a car losing control and speeding toward him. The last thing he heard was a screech before everything went dark.When Eric woke up, memories flooded his mind, and he quickly realized something was wrong. He wasn't in his own world anymore; he had somehow ended up in the world of “Humanity's Strongest Mage.” To his shock, he found himself in the body of Arin Vale, an insignificant character never mentioned in the novel—a true extra.Now, armed with the knowledge of future events and driven by a desire for chaos, Arin had one goal: to disrupt the smooth journey of Alex Whiteheart, the Protagonist. He was determined to introduce Chaos into the story, making it far more interesting than it ever was, and in the process, he'll also find out that there's more to his character than just being an Extra.Let the Chaos begin!
