Multiverse Academy with a Naughty System

"Very well, Issei-san. I'll fight you, but on two conditions." Basara said and lowered the sign.

"Well, two conditions? What conditions would that be?" asked Issei with both eyebrows raised.

"The first condition... You must tell at least ten people the result of our fight, regardless of what it is. The second is that none of us are obliged to use staffs, wands or any mana manipulation, but if you want to, you can."

"Well, that's fine with me for now."

"The third is that, even if you don't understand exactly what happened, you mustn't claim that I cheated. If you accept these three conditions, I promise that if I beat you, I won't charge you points for winning."

"That seems fair to me. I accept, Basara-san." Issei said, knowing that Basara wouldn't dare cheat with so many eyes watching him. "Come on, then. Show me what you're capable of."

Without saying another word, Basara took a few steps back and made a slight gesture with his hand, showing that Issei should follow him to the center of the courtyard.

The stage was a large stone platform, surrounded by four large torches. It was a simple arena in itself, but because it was in the middle of the Academy's inner garden, the students, even those who weren't around and hadn't even seen Basara with the sign, began to approach and try to understand what was going on in whispers among themselves.

Among the onlookers, a girl with short blue hair who was being followed closely behind by skinny boys saw what was happening and approached. She stopped next to a boy who seemed deeply focused on the arena. She then asked in a casual tone:

"Excuse me, what's going on here? There seems to be quite a stir."

"That first-year boy who made a familiar out of a human, Basara Toujou, showed up here with a sign saying that anyone who thought he was weak could call him out for a duel. It seems he set some conditions, but I haven't heard all of them. I think it's a fight without wands or something."

"Um... Is that so?" she commented, looking straight ahead.

After that boy's explanation, using so many details, she knew who Basara was. She just didn't know if he was strong or an idiot to be doing this. Compared to him, Issei was a slightly known boy at school, mainly because months ago some girls from the Kendo club beat him up with wooden swords for spying them changing in the locker room.

The girl smiled, interested in what was going to happen. Suddenly, she heard a louder sigh, and, when she looked over, she saw the boy she had asked staring at her with wide eyes.

His eyes were like that because, when he finally turned to see who had spoken to him, he saw that the blue-haired girl was Kurumu Kurono, an extremely beautiful girl whom many in the school admired and tried to get close to.

"A-ah, it's just that... he... I mean, Basara-san..." he tried to make conversation, but he could barely organize the words.

Kurumu lifted his lip slightly in disgust. "How about looking straight ahead and paying attention?"

He nodded obediently, almost without thinking, and looked back at the arena, his face expressionless, as if he had been hypnotized for a few moments. Satisfied, Kurumu turned her gaze to Basara and Issei.

At the center of the stage, Basara stretched his shoulders a little and asked:

"Ready to begin, Issei?"

"So... no wands or magic circles?" asked Issei with a smile at the corner of his mouth.

He waited for Basara to confirm the condition, perhaps even expecting a momentary hesitation from the boy, but all he saw was Basara's calm expression, and he nodded slightly.

"The condition stands."

Issei couldn't hold back the laugh that escaped his lips, starting as a whisper and becoming an open, frank laugh. "Fine with me, then! After all, I'm not very good at magic circles or anything like that. My style is more... physical."

Issei then stretched out his right hand and called for the power that inhabited his body, a rare and legendary power that was the subject of whispers and speculation throughout the academy: a Sacred Gear. A vivid, almost flaming red aura enveloped Issei's arm, and all eyes on him went wide. Instantly, metallic scales covered his entire right forearm, and a green jewel appeared on the back of his palm.

"Oh, I've heard rumors about Sacred Gear users at the academy, but I never thought I'd see one with my own eyes like this..."

As they watched Issei's arm turn into a metallic structure covered in glowing red scales, the buzz among the students increased

Issei raised his arm, now encased in his Sacred Gear, the Boosted Gear, and looked at Basara with a smile that oozed confidence. "I am the bearer of the Boosted Gear, this is one of the Thirteen Longinus and can amplify the user's power countless times... With each boost, my power doubles."

Basara didn't know what a Sacred Gear was and could feel a horrifying presence emanating from that Issei's right hand, but mostly his was:

'Why the hell is he explaining all this before a fight?'

Meanwhile, the surrounding crowd murmured louder and louder. Kurumu, the blue-haired girl who had been watching the scene with skepticism, now had genuine interest stamped on her face. She smiled, amused, muttering softly to herself:

"Did that boy have something like that all along? How interesting. Maybe I'll make him my slave."

Under the watchful eyes of the crowd, Basara remained calm, his expression only mildly intrigued as Issei's arm glowed with the menacing gleam of Boosted Gear.

"So, you have an interesting little toy, Issei-san."

Issei frowned, trying to figure out if Basara was joking or just being ironic.

"Toy? You have anything better?" Issei asked.

"I don't know if it's better, but..."

Raising his right hand, Basara's aura leaked out of his body, surrounding him. In an instant, the energy concentrated in his right arm, which took the shape of a silver sword with a long blade.

"I present to you my sword, the Brynhildr. It's not Sacred Gear, but don't think it's any less powerful for that."
