The Monsters All Want to Raise Her

Also known as "The Monster's Adopted Daughter" / "Raising the Strange"

Blurb:

"Why haven't I ever seen an alien, even now? Humanity is so useless..." Wang Xiaotian grumbled sleepily to her friend before bed. "No, wait. I mean the aliens are useless. I've been alive for so many years, and they still haven't come to Earth... When will I finally get to see one with my own eyes..."

So when she woke up, Wang Xiaotian discovered that she had become smaller, and that she really, truly had met aliens.

She was being stared at by a crowd of bizarre legendary creatures. It turned out they were all aliens QAQ

Ugh, is it too late to take back what I said last night? QAQ

After becoming a little short-legged girl, Wang Xiaotian gained an adoptive father who was prettier than any girl but afraid of the dark, a mischievous poltergeist big brother who loved stirring up trouble and whose whereabouts were hard to predict, a cool silver-haired teacher with a mechanical arm, wolf ears, and a wolf tail, and an adorable, shy little demon girl as her best friend. She also met fantastically beautiful yet dangerous creatures from the deep sea...

I-I want to touch them! Wang Xiaotian buried her face in the arms of her gentle, beautiful adoptive father, then turned her head slightly to peek at those beautiful yet dangerous beings, itching to reach out. Embarrassed, she buried her face again.

So cute. I want to... the monsters thought silently.

In the year 2023, natural disasters struck one after another, and human calamities never ceased. As a breeding tide arrived, many fantastical creatures from human mythology returned to the world.

In the year 2024, Wang Xiaotian was born, and the timeline split in two.

In one, humanity survived the disasters and began to thrive once more.

In the other...

"Xiaotian, let's escape! Those monsters treat us like pets, like lab specimens. They can't have good intentions!"

"Xiaotian, don't be afraid. Come here, I'll protect you. Your parents saved me, and they entrusted you to my care."

"Oh, you want to know what happened to your family? Call me Big Brother! If you do, I'll tell you!"

"The human who raised me? They were very gentle, and often took me for walks in the mountains and forests."

"I... I'm actually not a girl, but I'm not a boy either... I'm sorry... I was afraid you'd hate me if I told you..."

"Sigh, I really want to go back to the sea. Xiaotian, you've never seen the deep sea ten thousand meters below, have you? Want to go see it with me?"
