Rebirth Space Pretty Girl - Chapter 8: injured?

Once a regular high school student, the protagonist gets sent to another world via truck. He reawakens to find himself contracted to a girl about the same age as him before passing, and that his body was no longer that of a human. Given a new name as the girl's contracted spirit, he spends his days at her side._ _ _ _ _ _ _ _ _ _ _This is not a novel I will be updating multiple days a week. The most likely outcome is me updating it once a week, but if any readers would like to read my other works, I would like to suggest reading the story I update most which is “Level One Isn't Weak!”.

There was once an immortal cultivator fighting for the fate of human beings. Unfortunately, he failed that time; but fortunately got another chance as he was reborn once more as a human, on the earth of 5,000 years ago. With a second chance, he not only would embark on the road of saving all mankind, but also would retrieve his human nature on the new journey that would last for 5,000 years.

- Description from Novelupdates

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?

When the admissions office of Witch Academy called, I was stunned—I had been accepted into a school I never imagined I could touch.Yes, I am a boy and it is an all-girls’ academy, but they did not mind, so I saw no reason to object. I had applied secretly, without telling my family, just to take a chance.But as soon as those striking seniors greeted us newcomers—pressing every boy against the wall with a knowing smile—I realized things were about to spin out of control.“Oh, come now, you sweet little freshman,” one of them said smoothly, her voice full of mischief. “Don’t make this difficult for me, your big sis. Swallow this core and transform into a witch like me, alright?”She held the glowing orb before us, half-threatening, half-teasing, almost inviting the new boys to react. It was clear she enjoyed it—the blend of fear and resistance in their expressions. Our unease seemed to be her personal amusement.After all, they only had this opportunity once a year.
