Checkmate!

As Riser approached, he sent a blast of fire at Issei, **** to take him down. Issei responded by firing a Dragon Shot right at the flames. The attacks clashed momentarily, and then, Riser's was overpowered, and he was struck through the torso. "Urk!" Riser cursed, before Issei was on him, and had his fist drawn back.

"Boost!" Issei roared, channeling the Boost into the cross, doubling its Holy power. He then struck Riser in the face with it, punching through one side of his head.

"FUUUUUCK!!!" Riser bellowed as the Boosted Holy Power made it damn difficult to regenerate. Even when he succeeded, clear signs of damage were still visible on the right side of his face. He couldn't fully heal with the Holy damage being Boosted like that. "You're fighting dirty, you bastard!"

"Says the asshole who was set up to succeed from the start, and is still getting his ass handed to him!" Issei snorted, passing the Holy Water to his left hand, and breaking the top of the flask off with a flick of his thumb. Riser's eyes widened, and he tried to blast it out of Issei's hand. Issei managed to move his arm to avoid that, and thrust his right hand forward, index and middle fingers extended, stabbing them right into Riser's eyes.

"Gah! My eyes! WHY IS IT ALWAYS THE DAMN EYES!?" Riser bellowed. Before they could regenerate, Issei threw the Holy Water at Riser's face, Boosting the Holy power in it as he did. HISS! "GAAAAAAAHHHH!" Riser wailed in agony as the liquid sizzled against his face, and he staggered back, covering his face in his hands. Fun fact, Holy Water was doubly effective against a Phoenix family member. Water against his Fire, Holy against his Devil. Riser kept screaming, falling to his knees as he practically clawed at his own face. Rias watched in awe. She had considered joining Issei, but... in truth, there was just no need, and finishing Riser off himself would bea greater boost in his status after this Rating Game was over. She'd wait and act if she was needed, but she didn't see that happening.

(Trip-Innocent of D plays.)

Issei tossed aside the flask after emptying the remaining contents upon his gauntlet. "Thirteen!" Ddraig counted down, and Issei bit back a snort. He didn't even need half that at this point. He had Riser by the balls, figuratively speaking. Riser had lost too much power to stand a real chance before this fight even began. "How did that feel, Riser!?" Issei demanded as Riser shakily got to his feet, his face covered in horrific looking burns. "Asia taught me that crosses and and Holy Water are very effective against Devils! With both of them, and increasing their utility with my Boosted Gear, not even a Devil like you stands a chance!"

"Just fall already!" Riser bellowed, shooting a frantic burst of flame at Issei, who dodged to the side with ease.

"Kiba taught me to widen my field of vision, and focus on all my senses in battle, and helped me learn how to evade!" He pointed his left fist towards Riser. "Akeno taught me how to use magic, to focus my body's aura into a single point to amplify my attack!" Riser took a step back, watching what could only be described as pure power gathered into the gauntlet. "Koneko taught me to aim for the center of mass, to always aim to strike for the heart of my opponent! And Rias... Rias taught me how to be strong, and motivated me to always give it my all, and never quit no matter what! All of these things... are why I'm about to put you in checkmate!"

Terrified, Riser took a step back. "Stop... don't you understand, this engagement is important to the future of all Devils! Especially given the power Rias now holds! A mere servant like you could never utilize her capabilities to their maximum potential, and has no business butting into the affairs of his betters!" he panicked.

"You still don't get it do you?" Issei growled. "I couldn't give so much as a hair on a rat's ass about your damn politics! Rias is not just some tool, political, magical or otherwise! She's a person, and no one gets to control her life! Even though I could have all this time, I still choose not to! That's the difference between us, Riser, and why she doesn't want you as her Master!" He then charged right at Riser. "And that's more than enough reason for me to kick your ass!" He swung his fist as Riser couldn't manage to move aside in time. "Suck on this, you scumbag!"

His fist slammed right into Riser's gut, causing him to **** up blood, unable to regenerate at all anymore. He sunk to his knees, gasping in pain. "You... you bastard..." Riser groaned as he collapsed, and Issei drew his fist back to strike again to make sure Riser retired.

"Stop, that's enough!" Ravel cried out as she flew back from where Issei had flung her, landing between Issei and Riser, arms outstretched.

"...I'd advise you to step aside. Unless you want me to go through you," Issei stated to Ravel, who flushed, both from fear of the armored figure, and, though she wouldn't admit it, the barest hint of arousal at his power.

"Issei, that's enough," Rias stated as she approached, pointing at Riser, who was vanishing. "You did it. You won."

Once Riser had completely faded, Grayfia's voice spoke up again. "Riser Peerage, King put in checkmate. Victory goes to Rias Peerage."

Issei exhaled, dismissing the armor early. "...it's over then?" Issei asked.

"Yes," Rias nodded with a smile. "We'll be transported to the medical wing shortly. We can rest up there, and get back on with our lives..."

Issei nodded, before the glow took the three remaining pieces on the field. He could definitely go for crashing with his head between Rias's divine breasts right now.
