Super Ball Girls <-----Manga
**********
"So, this is the virus/alien being that can transform into women?"
"Precisely master, if they interact with any man, and get them to be excited sexually, kissing them or even anything with body fluids, will cause them to multiply"
"Interesting, let me see the thing that affects them"
Bidan let a sadistic grin, making the female alien in captivity, stuck inside a white room. As, the walls opened up then a tube came from them.
"Let me out! Don't!"
*pzzzzz*
Chocolate shot out from the tubes hitting the woman. Who was naked, she was a cute girl but the chocolate just melted her body.
"Well, that's quite disgusting"
"They're made of chocolate, their biology ended like that. We found the cause to who did it."
Dylan was curious of it all, seeing the girl die and disintegrate. He walked away with Bidan by his side.
"Can't wait to see them."

Dylan arrived at a warehouse, he walked form the shadows. He saw four girls with one young man. As he looked around nervously.
"It's good to meet you Ichi"
Five of them turned their heads around leading to the voice. As, Dylan was curious how he did it. He himself, was not very interested in their biology and how they work.
They're a virus from some distant place in the universe.
"Y-You're?"
He stuttered feeling a little nervous, as the girls around him. Cherry, Eliza, Autumn and Chrys were the girls name which the boy named them.
They felt a sense of danger, which they instantly went on guard.
"Ichi, he's dangerous"
Eliza glared at Dylan, as he chuckled.
"Don't worry, i'm the person you're supposed to meet, Bidan should've told you"
He raised his hands in surrender, making them feel just slightly at ease. Looking at him, he was a handsome man, but they didn't care about his looks. Only thinking about Ichi, who gave them a life to live.
Cherry knew he was handsome like that, she felt pulled but her devotion to him was strong. Besides, their was a promise a wish that Bidan had told her. Something, that which can make them enjoy a normal life.
The man in front of them can help them with it. Of course, Bidan never mentioned she could help them become normal. Without the ability to reproduce because of a simple kiss.
"We have a lot to talk about"
He walked closer, as he just gave a friendly smile. He wanted to know from this young man. The source of the virus.

"Ichi! We can be together, Eliza and Ichi forever!"
Eliza hugged Ichi, who blushed feeling her breast squish against his head. He liked it, as Ichi was pulled away by Cherry. Making Eliza glare at her but she wasn't mad. Cherry kissed him, making a face filled with ecstasy She was ecstatic, now able to to live with her sisters. They can love the man they love, without worrying about multiplying.
Ichi was drowning, he could cry now. Thanks to Dylan, he can actually have a relationship with them. And have a harem himself, he can die happy.
****************
Dylan looked at a woman who was the head of the whole operation. She was like those alien virus girls.
She felt fear for the first time, she was smarter than all the one's that multiplied before her. She, evolved experiences what humans experience throughout their life, generations. She felt euphoria that she can become much more. Seducing boys, men and older men to work for her. Making them dance around her finger tips.
She knew of herself being different, she ruled over the mass of her fellow people. Sending them to kiss, or have any sexual experience with other men. So, they can multiply and rule this world. This was their goal.
No
It was a part of them to spread everywhere like a virus. That's what they were, and so where humans. Now it's their turn to rule this world. But in front of the man before her.
She was to scared, she hit the desk, as she was crawling away.
"Wait! I'll be yours, with me and you multiplying, we can rule this world!"
She tried to sweet talk him, she had a perfect figure and she was beautiful. From this world standards, she was like a super model. Someone that many men would lust for and be happy to be with. She was still learning of this worlds history, rules, laws, desires. Everything that made this world prosper was from humans.
This man killed every single girl she had in this building easily. She was going to start with a small town, before she went towards a city to amass her forces.
"Just dissapear"
"NO! I'll let you do anything with me, my body is yours!"
She tried one last time, only for her to be exterminated by an energy blast.
Chocolate splattered everywhere, Dylan saw a ball that was their heart, their life. An eye stared at him with fear. It tried to bounce out, only for it to be grabbed by him.
"Your time is done here in this world."
He crushed it, ending the start of a invasion.
