DxD: Brain

"Ara, what a flirt? You know, you could always help me get Kunou a sibling~? I could call you 'Da-'"

"And with that, I'm late for training, see you, Yasaka-san!"

The nine-tailed Youkai just giggled at his departing figure, "I told you I would watch out for him but you didn't tell me that he was going to grow up handsome~. "

Kasane left Kunou's room, closing the door, where she went to go find Hiroki. It wasn't hard after feeling his power out on the training floor.

She entered the room and saw him in his outfit. The outfit in question was something called [G.

Attire: Endless Candor]. The outfit was primarily black with blue, white, and silver accents.

It fit him pretty well, almost form-fitting but was slightly baggy in the pants and sleeve areas. If he added a trench coat, he could pass off as some important lieutenant in the Yakuza.

The pattern on the jacket and pants almost looked like 3D diamonds. Kasane idly observed Hiroki in his zone, practicing flips, kicks, punches, and multiple other combos.

"Are you going to join me or are you going to stare at me?" Hiroki asked without turning around. There was a reason on how he knew she was there.

"Well, I got dressed for the occasion," Kasane responded plainly. "How was Yasaka-san?"

"The usual. " Aka, she tried to seduce me but I declined because as stunning as she is, there is one person I need first… is what he wanted to say.

"Hiroki-kun, I'm honestly baffled on why you don't take her up on her offer," Kasane was blunt in her words as they have had this conversation before. Despite the feeling that Kasane doesn't want to bring up—jealousy—she continued, "Do you honestly know how sought after she is?"

Hiroki scoffed, "The word is lusted, Kasane-chan. " The training room had a wide floor that was perfect for sparing, some weight-lifting sections, and some meditation chambers.

Perfect for Youkai, and them. "I can't because I…"

". .

. well?"

Hiroki sighed, "I just can't…I'm not ready. "

"Is that how you're going to confess to a girl in the future, Hiroki-kun?" With a flash, she changed out of her Kuoh Academy uniform and was now in [G. Attire: Eternal Sorrow] and rushed after Hiroki.

The outfit was in the same series as [Endless Candor] and looked similar too, except for the red and white accents to his blue and silver-white accents. Also, two tassel-like strips extended off of her shoulder blades, making them flutter in the wind.

The uneasy look on Hiroki's face vanished and was replaced with a feral one, "Oh? Insulting my pride as a man? That has steep consequences, my dear Kasane-chan. " Her attack was useless as he grappled her and tossed her aside.

She hit the ground once before adjusting herself to a crouch.

The difference between them was how they fought. Hiroki was more in line with a solid fighter while Kasane was more of a speed fighter.

Kasane then brought out her weapons. Surrounded by a purple glow, multiple war fan-like blades sprouted from her back.

"Well? How are you ever going to confess to any girl? What if they confess to you?"

She was taunting him and he knew it but he won't rise to the bait, not ev-

"Maybe I should ask the guy who guessed my sizes-"

The air around Kasane shimmered before the white-haired girl jumped up, sending her blades at him. Hiroki moved from his position, dodging the first two fans, the third slipped by a mere margin.

The fourth blade collided with a solid object…except there wasn't one.

This is where Kasane's personality shined, where she expressed herself more. Something that doesn't happen often.

Hiroki took the blade in front of him and sent it back to her, just by blowing on it.

To explain, Yasaka mentioned Sacred Gears. Both Hiroki and Kasane possess one.

This is their 'Second Liberation' form. The purple glow that surrounds Kasane's war fan blades is a power called Psychokinesis.

She can throw objects and or people if they are able to be held—line of sight and other such constraints. This, however, drains Kasane's ability to use her Gear.

There is a mental strain depending on what she is trying to affect with her power. For Hiroki, the power of his Sacred Gear allows him to control soundwaves, frequency, and density of them, making them a solid transparent object.

That was how he stopped Kasane's blade. This was called Sonokinesis.

The two continued to exchange blows as Hiroki cupped his hands over his mouth and started firing sound bullets by amplifying his vocal cords. Kasane ducked behind a meditation chamber, hearing them hit before a force pushed her to the chamber, keeping her flush to it.

"What was that, Kasane-chan? You were saying?" His teasing voice angered her. He was mocking her.

The white-haired girl glared at the navy-haired boy before she smirked, "You haven't answered my question. " On her outfit, a hood formed over her face, and one eye glowed red while the other was covered by the hood.

"[Balance Breaker: Psycho Brain Drive!]"

Kasane easily broke out of her sound prison and used the chamber he was sitting on and sent him flying. Hiroki jumped off it and used his power to stop it from being destroyed.

Kasane leaped at the opportunity and sent him back with a punch to his chest.

"First hit goes to me," she said with a smile under the hood.

"Finally getting serious, are we? Fine. "

"[Balance Breaker: Sono Brain Drive!]"

A similar hood came over Hiroki's face, except for the fact a mask covered his mouth. His eyes also glowed a similar red to Kasane's but two were visible compared to one.

In order to combat Kasane from range, he would have to get a little creative. He started creating what he called 'sound grenades' before sending them to her.

Kasane used her blades to cut them but Hiroki was adept in his Brain Drive. This form allowed the two of them to process the area around them, making their fight faster.

To compare, one second to them is around three seconds. While three times the speed of time sounds unreal, the boost to their brains causes them to react faster.
