Love is Deception

It's been two years after the Dark Dragon Blade Incident. Ryu Hayabusa still remembered that day.
The day the love of his life killed herself to save him.
Now it will come back to haunt him in his next adventure.
A CIA agent, Sonia, informs Ryu of a Fiend Cult that's going to resurrect the Archfiend. Now that they have the Princess back, the Archfiend can produce more broad and more powerful fiends.
Ryu will not allow that.
But upon meeting the girl in person...
Will he be able to kill her?
Or will the memory of his love stop him?
