Ryujin were known for being a powerful princess in the empire, the first born of the king. Their clan were known for being the greatest user of green flames and all of the King's children manage to inherit his power.
King Shin had total for 4 kids, 2 sons and 2 daughters: Shin Ryujin, Shin Seungmin, Shin Wonho and Shin Yuna. On all of his children, Ryujin is the one who excels in using the green flame and her flame is much stronger than anyone.
The one whom you beat to death was Shin Wonho. Beside for being known as the powerful princess of empire, she was also known for her bad personality and bad habits. The people branded her as "The Evil Princess Of Shin Empire" or in short "The Evil Princess".
Outside the empire there was this place called "Fer de Ud". A village of Sorcerers and warriors, this is where the empire is recruiting soldiers and sorcerers and this is the place where you and Yena came from.
This village were also known for having powerful sorcerers and warriors and one those powerful people were You and Yena. Both of you were trained to become sorcerers and warriors but you guys refused because you heard that the capital were full of evil royal blood.
In short, both of you and Yena retaliate to avoid getting used by the empire as defenders of empire for it was full of evil people. But upon this forceful act of putting you and Yena to empire, you and Yena manage to kill some of the sorcerers.
They saw how powerful you are and Yena which scared them. They didn't force you and Yena and leave you guys alone.
Now Ryujin is facing Yena which she haven't heard of her past. Yena can destroy a whole city if she wanted to and you can dissipate every people living in the empire but you guys are peacemakers.
"Your strong I give you that" Ryujin said
"I have heard about you from the capital" Yena said with pink glowing eyes "And it's not pleasing in my ears"
"Well that tittle is not made to please people, it was made to threat every one who oppose me" Ryujin said
"Well my powers were made to get rid of those who oppose peace" Yena said and raise her arms and clench it
"Your highness we should avoid getting into fight" Jeong in said
"Well how can I avoid it? I have finally found the sinner who beated Wonho to death" Ryujin said
"Really your highness?" Jeong in said
"Yeah, that guy" Ryujin pointed at you
"Never take your eyes off your opponent" Yena charge towards Ryujin
"Damn it! Flame burst" Ryujin throwed a laser flame on Yena
Yena smirks then she block the flame using her right palm which surprised Ryujin
"What the?" Ryujin said
"Is that all?" Yena said laughing "If that's all let me bring this back to you!" Yena said
"What?!" Ryujin said
"Flame burst!!" Yena said and fire pink flame laser collide on Ryujin's green flame
"What the?" Ryujin move away and saw how strong Yena blow is
Ryujin saw the ground where she was standing before we're burned.
"Guess this settles it" Ryujin charge towards Yena
"Oh fist fight?" Yena said
They started exchanging punch and kick and you were also surprised because Ryujin can keep up with Yena which made you chuckles.
