Write an anime scene that shows off Kuroi's brother, Kuroki's, abilities with his swords. Note that Kuroi is so strong he needs to tone back his skills, but we don't see his test yet. Nezuko, a haughty woman, is impressed with his display of skills at the hunter examination. Make it around 250 words. Put it in the third person. Include dialogue.

Kuroki whispered to Kuroi, "Hey, are you sure about this? Aren't you just letting her get under your skin?"

"Isn't this what you wanted in the first place? This is why you brought me here, no?" Kuroi pointed out, his expression flat.

"Well, sure, but I always knew you didn't care about this, so I didn't expect that you'd want to take it seriously. It could be bad if you go all out," Kuroki said. The line for displaying their talents was shrinking, and Kuroi sighed, seeing the desperation on his brother's face.

"Fine. I'll reign it in just enough to prove that whats-her-face girl wrong."

Kuroki sighed with relief before he was called to the front. "What's your skill?" the proctor asked. 

"I'm known as the seven-blade swordsman. My skill is with the sword, naturally."

The proctor wrote something and told him to show his ability. There was an electronic target dummy that registered each person's skill at various levels. Kuroki, wearing six swords on his back, stepped forward. He drew his swords and moved like a glittering bolt of lightning, unleashing a torrent of strikes and using the swords so fast that the blades overheated with each blow. Everyone was astonished and the proctor wrote down various data points and statements. Nezuko said, "Wow. I'm surprised. You might be able to achieve S-class in the future if you're already this good."

Kuroki replied, "I held back some so I didn't destroy the equipment. 

"How thoughtful," Nezuko said genuinely.
