DxD: A World Where T*tties Defy Gravity [ Chapter 71: Worthless! ] (Patreon)

"Isane, go for Riser and keep him busy!" Rias shouted, flying upwards and conjuring up a blast of her Power of Destruction. "Mira and I will get him from long-range!"

"It won't work, you know!" Riser shouted, as Isane, still clad in her Balance Breaker armour, rushed forward, using her four Dragon wings to elevate herself into the air, and Mirajane switched to her original Satan Soul form, joining Rias in the sky. 

"No matter what you do, you will fail against me!"

"Oh, fucking shut up!" Isane shouted, conjuring a huge blast of demonic energy, Boosting it up and sending it at Riser. 

It blew off his arm, but as it regenerated, Isane flew towards Riser and punched him into the face, sending Riser flying backward, straight into a blast of lightning from Mirajane, that caused him to scream in pain.

"Fuck you!" Riser shouted, placing both of his hands together and sending a huge beam of fire at Isane. However, Isane was long gone by the time it got anywhere near her. "IT'S NO USE!"

"TAKE THIS!" Isane yelled in reply, coming at Riser from below and punching him hard in the crotch with everything she had In the booth, Rex, Sirzechs, Sairaorg and Renzo all inwardly winced at Riser's misfortune. 

"AND THIS!" She fired another blast of Boosted demonic energy at Riser, that was powerful enough to tear a hole in his stomach.

"AND THIS!" Rias continued, creating four more balls of Power of Destruction, which she used to blow up Riser's arms and legs. However, these, along with the hole in his stomach, regenerated within an instant as he righted himself in mid-air.

"YOU DAMNED BRATS!" He shouted, subconsciously raising his hand to create a shield that blocked the swing of Kiba's Sword of Betrayer. 

"ALL OF YOUR ATTACKS ARE FUCKING WORTHLESS!"

As Riser continued his rant while focusing his attention on Rias and Mira, Isane heard a voice coming inside her Boosted Gear.

["Hey, Isane?"] Elsha spoke. ["I hate to be the bearer of bad news, but..."]

"But what, Elsha?" Isane asked, trying to fire another shot of energy at Riser, but missed.

["You're running out of time in your Balance Breaker."] Elsha said, slightly solumnly. ["Once you run out, your armour will disappear, and you'll be powerless."]

"Well, that's just fucking great." Isane replied, sarcastically, while dodging a punch from Riser, who had turned his attention back to him. Big mistake, as Rias blasted Riser in the back again. "How long is left?"

["One minute, Partner."] Ddraig replied. ["And counting."]

Isane grabbed Riser's fist in her armour-clad hand, and punched him in the face so hard it ended up breaking his nose, and kicked him in the stomach, sending him backwards in the air a few metres.

["Fifty seconds."] Ddraig called.

"This is it, brat!" Riser roared, turning his attention fully back to Isane, and firing attack after attack at her. "This has gone on for long enough! Surrender now, and I won't have to destroy and humiliate you in front of my entire peerage!"

"NEVER!" Isane roared back, her voice under the armour more like a Dragon's growl, her armour tanking the attacks that came into contact with her. 

"It's you that's going to be destroyed! We got your sister, who has the same power as you, so it's easy that we'll take you down!"

["Forty seconds."]

"BULLSHIT!" Riser screamed, firing more lasers at Isane, which she managed to dodge, and counter with demonic blasts of her own.

Meanwhile, Rias was reaching the end of her tether. She panted heavily as she sent a blast of her Power of Destruction at Riser, but it proved to have little to no merit as, though it blew open his spine, his body regenerated in an instant.

'I trained for six months for this...!' Rias thought, wheezing. 'I swear that if I come out of this the victor, I'll do anything, literally anything, to thank Rex for this!'

"Are you okay, Rias?" Mirajane called, as she tried to trap Riser in a huge bubble of water, but it was evaporated faster than she could form it.

"I'm... fine!" Rias coughed, trying to force down the slightly nauseus feeling that came in her stomach, as she fired yet another blast of Destruction at Riser, in an attempt, ANY attempt, to distract him. "I'm okay, Mira!"

["Ten seconds, Partner!"] Ddraig warned. ["Nine... eight... seven..."]

Isane looked up, and as he punched Riser in the stomach and sent him backwards, she saw Kiba coming at him from the side, Sword of Betrayer in hand. Riser, evidently, noticed this too, as he created another shield to block Kiba's sword. 

However, Kiba saw the shield coming, and flew downwards, and then upwards, swinging hard, and actually making contact with Riser's side, but not enough to deal any significant damage, instead only leaving a light scar there with his Holy Demonic Sword. Nevertheless, Riser still hissed angrily in pain.

["Six... five..."] Ddraig called, as Isane noticed that the scar that Kiba left with his Sword of Betrayer flickered with flame for a moment, and healed only partially. 

Then the flame died for a moment, before coming back with full force, as Riser's scar healed.

["Four... three..."]

"KIBA!" Isane yelled, to get Kiba's attention, while ducking under Riser's punch, and thrusting her left arm out, Transferring all her remaining power to Kiba. "You know what to do!"

[Two... one... time!"] Ddraig called, and at that moment, Isane's armour disappeared, and Isane, suddenly having no Dragon wings to keep her in the sky, began to fall. 

She fell the full ten metres that she had been flying in the air at the time, and landed on the ground with a very unpleasant CRACK.

"Rias Gremory's Pawn has been retired." Grayfia called, as Kiba suddenly realised what Isane meant when she said "You know what to do!"

As Riser gave a loud crow of victory at the sight of Rias' useless in his eyes Pawn being retired from the game, like the Low-Class scum she was, Kiba flew forward, his Sword of Betrayer glowing with a harsh light, and swung it at Riser, who was too late to stop it from happening.
