*Huck!*

With a grunting sound, the girl hit the ground while holding her sides. Opposite of her stood a tall girl dressed in high school uniform looking down girl on the ground with glee. There was a tint of red noticed on the girl's cheek as if she has done something praiseworthy.

"Heh, that felt good, miss black belt."

The said girl prepared to leave but felt a little tug on her shirt. Turning around, she noticed a miss black belt who supposed on the ground clutching her shirt while trying to stand up, she spoke.

"I'm n-not done!"

Observers already knew girl, using last of her strength trying to stand up. It looked like a beaten up hero trying to rise up against villain. Seeing this act, everyone wanted to cheer for her, but sadly they know how those end.

"Yep, that is right."

With a friendly smile, the tall girl spoke and raised one of her arms at the same time onlookers saw how quickly her friendly-looking smile change into scary expression as if she about to kill her. Then.

*Pow!*

She dropped her palm on the girl's back, making loud sound followed by a girl's body hitting the wooden floor.

"That made a nice sound."

Praising her perfect spike, a tall girl walked back to dojo's entrance.

"Oh, don't forget to tell miss black belt that I will arrive tomorrow."

Said tall girl leaves the dojo with her usual smile leaving gloomy members behind.

They know she will come tomorrow and they can't do anything against it. No, their pride as members of a karate club stopped them from reporting her to a teacher. They can't say members of the karate club lost to a single person from the volleyball club.

"I don't believe it, why we can't beat her."

The story has been stolen; if detected on Amazon, report the violation.

It was frustrating but, they can't deny the girl Asaka Yuriko was a genius. She had everything that martial art practitioners wished for the strength, weight, body type, talent. 

But the only thing she has done using her talent was to bully and look down upon them. As everyone in school knows, she doesn't dwel in club in three week. They wanted to know the reason where she always beat up their captain, but their captain and master refused to answer them.

-At night-

After finished eating her dinner Yuriko, laid on her bed. Thinking a pathetic looking expression of miss black belt, she smiled again. But her smile immediately cut short by the scene where she tries to stand up.

"Tsk. As always."

Yuriko hated that self-righteous part of her as if she stands up against something evil. But no matter how much she tries to act as a hero in front of her. In her eyes, she will always be a person who killed her brother. Even now, she still sees her brother lifelessly dangling from the ceiling of his room.

"Fuck!"

Clenching her teeth in anger, Yuriko closed her eyes and tried to sleep, wishing for tomorrow to come fast. But sadly, tomorrow never came as her heart suddenly stops beating in her sleep. It was a rare case of Sudden arrhythmic death syndrome or knows as bed death.

--

"Here, a full-grown twenty lab rats."

"Yes, I was waiting for this."

Following the conversation, Yuriko wakes up by sudden shake and clanking sounds of the iron cage.

Opening her eyes, she saw a giant man standing behind an iron cage and placing her on some sort of table. Looking behind the man, she saw an old man with a head full of white hair dressed lab coat handing stack of a bill to a shady-looking man dressed in a brown sweater and black pants.

"Are they good ?"

"Don't worry, Mr. White, those rats are special kinds that supplied to Zera research institute."

"Good."

'Rats ?'

Hearing the word, she immediately raised her hands and saw two purple claws with four fingers instead of her human hand. Moving her head, she saw furry butt with a long naked tail.

*Squek!*/What?/

Yuriko had no words to describe how is she feeling right now. She was woken up as rat and not just any rat but a test rat. Right now, she is one of twenty lab rats in a cage placed around edges of the room.

The room itself looks like made from wood and cement. With dried paints that seem like old tree bark about to drop with a gentle touch and cold wind blowing time to time in between walls, it was hard to call laboratory.

'Fuck, well first I need to warm up my felt before freezing to death.'

Shivering from a cold breeze, Yuriko decided to go the edge of her cage to warm herself up.

"Just when her body was getting warmer up, a cold robotic voice rang through her head.
