"Lock!" Jet called, and Weiss immediately lunged, not prepared to let that happen. To her surprise, Jet immediately took flight with his wings, dodging her attack, and Weiss realised that the lock had failed, but if Jet dodged, then that means…

"You expected that to fail?" she slowly asked as Jet landed behind her, not bothering to turn around.

"I don't know what happened to my locking ability, but consider it disabled." Jet replied. "Now that my three main advantages are useless, may we spar? You two against me."

"There's only one other thing we won't allow." Blake commented. "Your Super Activations."

"Seems fair." Jet deadpanned, before taking flight and hovering in the air. She watched with Blake as he unfolded his classic weapon, Midnight Rose. A copy of Ruby's weapon formed out of darkness which had been both strengthened and modified by Jet. Ruby definitely had Jet beat in terms of sheer speed, but Jet was already becoming her equal in terms of their weapons.

The aura indicators at the side of the training ground blared into life at his gesture. Jet then landed before addressing them. He slashed towards his own indicator, and a blue line appeared on his bar, fairly close to the end point of the gage. If Weiss had to guess, she'd think it was about 15%. But why did he mark the meter?

"At that line's point, I will trigger my super activation in a real-life duel." Jet explained. "You simply have to get me to that point. I win if both of your auras are in the red. That sound alright?"

Weiss smiled despite herself. That only happened when their auras hit 5% or less. Jet had just set the task of dealing 95% of damage to both of them, without taking 85% himself. There again… he seemed pretty confident.

"Begin!" she called, before firing several fireballs at him, Blake catching her drift and switching Gambol Shroud to gun form, before unleashing a withering hail of bullets to compliment the barrage of fire. Jet immediately took off, blocking Weiss' fireballs and dodging the bullets, before he pointed at both Weiss and Blake before clenching his fist and raising it upwards, a blue flame in his palm.

Weiss suddenly felt heat below her, and looked down, but immediately dived out of the way of a pillar of flame that had appeared at her feet. Blake, having better senses than her, had moved already, but she dived again suddenly. Why would –

BAM!

Weiss was blasted backwards and upwards by a second flame pillar, and she felt her aura take massive damage even as the gage plummeted to somewhere about 45%. From the ground, she watched as Blake dodged yet another blast.

How was he that strong?

She checked the aura levels. Hers and Blake's were stable, but Jet's aura seemed to decrease with each of his attacks. How had she not realised it before? Getting up, she shot a very small, but very fast, pulse of ice at Jet, which connected and sent him plummeting back to the ground. Weiss ran over to Blake as she caught her breath.

"Blake! I've figured out how Jet's so strong! He's not only using dust!" she said to her beleaguered teammate. Blake merely nodded as Jet started to rise, gesturing for Weiss to continue. "He's using his own aura to replace some of the dust and allow for more attacks. We just have to outlast him."

Weiss knew about these kinds of attacks from her studies prior to attending Beacon. Only certain individuals could use these dust-based attacks. Instead of just dust, the user projects force using part of their own aura, creating a devastating barrage of explosively powerful attacks that could be used again in a short space of time.

The drawback was that the aura would steadily be depleted with each attack, and eventually the attacks would fail because the aura would be completely consumed. This would have the effect of rendering Jet defenceless if it happened! It was probably Jet's uncopied semblance, and the reason why, when compounded with Dark Ultimatum or his Super Activations, they became unstoppable.

With that in mind, she brought herself back to reality, and nearly missed Blake's charge against Jet, who met her head on.

Weiss checked Jet's aura as she sent three icy blasts at Jet. Jet deflected each with a black energy shield, and his aura decreased from 85% to 75%. As Blake slashed in a series of confounding patters and dodged the returning swipes from Jet, which were shrouded in purple flames, his aura started decreasing, from both blocking Blake's attacks and retaliating.

This continued until Jet's aura reached 45%, when Weiss realised, after firing another barrage of fireballs, that Jet started to radiate red light. Before she could warn Blake, his red shockwave attack blasted from his chest, sending Blake flying and causing her aura to plummet from 100% to 35%, and Jet's to drop to 25%. Weiss saw Blake's go down another 5% when she hit the ground, and seized her chance.

She used a glyph to speed towards Jet, aiming her rapier directly at his chest, knowing his aura would cover him. She smashed into him, knocking them both down, but Weiss leapt away as a red glow surrounded Jet. The pulse never came, however, and Jet instead rose, his aura at 16%, just an inch off the blue line on the gage. He did not attack, however.

"Well fought. I concede." Jet said, and fired an ice attack into the air, causing his aura to drop below the blue line. He immediately surrounded himself with an aquatic blue substance that appeared out of nowhere, and Weiss saw his aura start to rise. Within half a minute, it was back at 100%, and with a splash that covered both Weiss and Blake in the soothing, cool liquid, it vanished.

"We managed to work out how you're so strong." Blake commented to Jet.

"Oh?" Jet queried.

"You use your aura as well as dust." Weiss explained. "You clearly didn't have any way to attack us without using any more aura, so you forfeited." At this, Jet grinned and closed his eyes.

"I knew you two were smart. Yes, I use those forms of attacks. This is my original semblance, beyond my ability to copy other semblances." Jet said, taking a short bow. "And now, I must bid you two farewell."

He took off, ignoring Weiss' 'Wait!'.

'What was with him?' Weiss asked herself, as she turned to look at Blake.
