Riku watched Rias' new Pawn as they handled Visor in a show of what all the different Evil Pieces did. The boy was amazed to say the least but what made Riku worry was that it was some Fallen Angels that had killed the boy in the first place, at least that was what Issei's memory had shown. The son of Gremory bid his sister a good night before teleporting back to his house, entering the science lab and started creating some side project he had started but lost interest for some time.

As he fiddled with the metal contraption, Riku's thoughts wondered to the previous day's events and how it correlated to the recent attacks on Issei Hyoudou. The boy was a trouble magnet, as seen by the fact that he couldn't do anything by himself without trouble knocking at his door. One such fact was the failed murder by a fallen angel only two days ago…

Riku stood with his sister as they glared at the fallen angel; Issei was on the ground behind them. The fallen wore a coat, fedora and gloves, complimented by his shoes and pants. It was clear that Issei had been attacked without warning, as the fallen had just stepped from the shadows with a light spear in his hand.

"Well then, more devils, how convenient for me." He said, clearly the fallen knew that he was outmatched.

Riku looked at him before speaking "Why are you here, Dohnaseek?"

Dohnaseek shrugged before pointing his weapon at Issei "Pray that we never cross paths again, your King and Riku saved you but I will not hold back next time."

With that threat, Dohnaseek took off, leaving a stunned Issei, worrying Rias and a thoughtful Riku in his wake.

Riku knew that that threat wasn't an empty one either, but it would be less of a threat when he had the boy trained by his Queen, though it was somewhat hazardous for both of them as they were the Heavenly Dragon Emperors.

Finishing the metal object up, Riku stood and left the lab, leaving the object in a stasis field so it wouldn't explode. He entered the elevator and rode it to the main floor, his mind on who could have sent Dohnaseek to Kuoh in the first place. Dohnaseek was under the command of Azazel, whom Riku had a scientist at arms partnership with, but Azazel would have sent someone more qualified for the job, if that was what Azazel wanted.

Riku knew that Azazel would want to meet a sacred gear user but in no way harm or kill them, it was against his moral code, if the fallen had one that is, Riku didn't know. So it was likely that Kokabiel or someone of the same mind had done it, why though?

Exiting the elevator and walking to the kitchen, Riku pondered on this thought as he entered the kitchen and made himself a sandwich. Finishing it, Riku started eating until Issei ran into him.

"Augh!" Riku quickly caught Issei before he could fall by the arm and pulled him up.

"Sorry, I should have been watching where I was going." The brown haired boy said, clearly out of it.

"Issei, something has you like this and it doesn't look good, so what is going on?" The Gremory asked, placing a hand on the boy's shoulder.

The Red Dragon Emperor was clearly reluctant to answer; his posture was that of a defeated man. Rias must have warned Issei to not fight the fallen, Riku knew Issei had the power to easily beat the Fallen in combat but he hadn't awakened Ddraig yet. He would fix that promptly, here and now.

"Issei, I want you and my Queen to start training together, you are the Red Dragon Emperor after all" Riku said, leading Issei to the training arena his sister had installed.

Issei was taken aback at that "What~?!"

"Yes, that scared gear you have" Riku pointed at Issei's left arm, making the teen look at it and take a sharp intake of breath when a small, two horned, glove gauntlet appeared "Is the hidden form of the legendary Boost Gear. If trained properly, you can be a million times better than those fallen and anyone else that gets in your way"

Issei nodded, clearly he needed this, Riku smiled and they entered the training arena. Riku noticed Harry and Hermione having a wizards duel while Akeno oversaw the match, Koneko was sparing with his Sister, Kuroka and Kiba was facing Percy. Riku smiled as Issei watched in shock, of course, this wasn't a sight you see every day.

Riku's weapon appeared at his hip, turning to Issei, he said "You might want to watch this, it will help you an Idea of what my sister's and my peerage are capable of"

Issei nodded, too shocked to do anything as Riku grinned and teleported to Percy and Kiba, his sword in hand. Kiba was first to notice the new addition and deflected the blade of Riku's sword with a swift slash, Percy jumping back and held his own weapon at the ready. Riku smiled and charged, the sword of Cortes slashing in a downward arc at Kiba before changing direction and slashing at Percy.

Percy blocked and Kiba went in for the final blow but Riku spun and caught the sacred gear devil's sword with a simple parry before spinning his wrist. The sword of the conquistador cut Kiba's blade clean in half, before Riku kicked Kiba into the wall. Percy held his ground, Riptide held in one hand as he had picked up the broken sword as well. Riku nodded at his pawn before attacking, Percy used both swords to block Riku's attack and strike back, the blades creating arcs in the air.

Riku deflected them with some difficulty, Percy was slightly better than him in sword combat. Riku in a last ditch effort to beat Percy changed his angle of attack at the last possible second, allowing Riku to knock both of the swords out of Percy's hands. Riku grinned and sheathed his sword; Percy had a grin as well.

"Thought I was going to win that time, Riku" Percy said as he helped Kiba to his feet.

Riku nodded "I thought I was going to lose again, nice job though"

The demigod turned devil nodded and Riku turned to an impressed Issei. Miya was behind Issei and she smiled her sacred gears wings were folded against her back as usual.

Riku walked up to them "Hey, Issei, here's Miya. She's the White Dragon Emperor and she'll be your trainer, that good?"

Issei smiled "Yeah, that's more than good!"

Riku nodded before he noticed Risa walk in and motion to him. He walked over and gave his younger sister a confused look.

"What is it?" He asked in a low voice.

"Sirzech has told me that we are going to have more problems. The Fallen that attacked Issei went Rogue and haven't been following Azazel's orders in any way." The Crimson haired Gremory answered.

Riku got a serious look on his face "Who are they, Dohnaseek is one of them but who are the others?"

Rias shrugged "I don't know, but they are very serious about kidnapping Asia…I'm worried for her."

Riku stiffened "I won't let Asia be taken, I swear on it"

Rias nodded, before hugging Riku. Riku returned it as he watched Miya and Issei train for a while. He would keep his promise no matter what, but now he had to watch and wait for the rogue Fallen to try anything.
