Jump his ass!

"Just patch me up well enough to throw some punches, then heal up Akeno!" Koneko told Asia as she was healing the petite young woman.

"You think I'll let you!?" Riser demanded, charging forward. Only to get blasted point blank by Rias's Power of Destruction. He snarled as he reconstituted himself, before grunting as Kiba stabbed an ice blade through his chest.

"Raynare, keep Ravel at bay!" Rias shouted as Issei brought out his Boosted Gear, and triggered the first Boost. They'd hoped to use the Holy Attacks on Riser, but Ravel was an unforseen element that Rias deemed more important to prevent interference from. Numbers should be enough against Riser anyway. "Asia, keep back, once you've healed Akeno! Everyone else! ...sic him!"

"Understood!" everyone nodded, before Riser blasted Kiba away, scorching his front. Kiba grunted in pain, but rolled to his feet. Before Riser could follow up, Rias blasted his arm, forcing him to restore it.

"Boost!" Issei shouted, before punching Riser through his head with his right hand, particularly his eyes.

"Argh!" Riser staggered back, regenerating, but momentarily blinded while his eyes were gone, allowing Rias to blast another shot through his torso. Issei meanwhile shook his hand, which had pinkened. It was like Riser's body was made of fire when struck, which slightly burned Issei. Mental note, use the one with the gauntlet from this point.

"Big Bro!" Ravel shouted, flying forward to try to intervene, but was **** to immediately backtrack to avoid Light Javelins from Raynare.

"Sorry, but I got a job to do, and that's to keep you from interfering with your brother being gang banged," Raynare chirped at Ravel, before flying right at her, Javelin in one hand, the cross in the other.

Ravel shrieked, and began shooting rapid fireballs at Raynare as she flew to keep Raynare at a safe distance, making sure to circle so she could aid Riser if she could only get some breathing room. For the moment though, she was preoccupied dodging Light Javelins, and staying the hell away from Raynare so she wouldn't have the chance to use the cross.

Riser meanwhile was basically being hit constantly. Several roofing tiles went through his face and neck, courtesy of a patched up Koneko joining in and pulling them up, using them as improvised shuriken. Issei then landed a Shoryuken on him right as Rias blasted his legs out from under him. Asia had started to heal Akeno and share some magic energy with her.

All the while, Riser wasn't being given much chance to hit back. Kiba rushed in again, but just before he could land his attack, a fireball came down, which he barely avoided. Ravel had managed to put up a fire wall between herself and Raynare, buying herself a couple of seconds to attempt to disrupt their rhythm before she had to leg it, er... Wing it away from Raynare again. "Hold still, damn it!" Raynare cursed. Ravel was pretty damn fast, making doing her job a little difficult.

Riser immediately seized the opening to try to attack Kiba, but was foiled when Kiba produced a blade that flashed light at Riser. Not Holy Light, just regular light. Which was good enough for what was basically a flash bang. "Argh! Again with the fucking eyes!" Riser cursed as he staggered back, before getting an ice sword to the neck.

Issei followed up by punching Riser through the back of his head, getting stronger and faster with every Boost he utilized. "All's fair in love and war, and this counts as both!" he taunted Riser.

"Damn trash!" Riser cursed, pulling his arm back to throw a fireball at Issei, only for the arm to be temporarily severed by another roofing tile. Then he shrieked as Rias nailed him right between the legs with another blast. "That was uncalled for!" he whined at Rias, who glared daggers at him.

"Call Issei trash one more time, I fucking dare you!" she roared, blasting him again.

Riser staggered back, regenerating as they kept chipping away at his willpower. He had to break this stun lock, before- Zap! ...that. Before it got worse, via Akeno jumping in, which is what had clearly just happened. He was being struck repeatedly now, never more than half a second between strikes as the entirety of Rias's Peerage, minus Asia and Raynare, worked in perfect tandem to keep up a constant barrage that gave him no opportunity to defend himself. He had to stay calm, and not panic, despite genuine worry creeping into his mind. If this kept up for too long, he would lose. He was coming up with a plan, but he needed an opening to use it. Just one measly second would do...
