The Untouchable of Magic High School – A New God Enters the Game

Exhausted from yesterday's events, I fell asleep before Miyuki. My need for sleep won out, but that's better than lying awake with nerves. Honestly, I'm grateful for last night's slumber.

It's been a while since I slept beside someone—usually my little sister. Back at the main house, she clings to me like Miyuki does in the original story, and I dote on her. Jirou, stop giving me those jealous looks. I have basic morals and ethics; even as a reincarnator, I'd never consider marrying my blood-related sister. Besides, it's absurd that Shina's future is being debated by her six siblings instead of our parents.

When I woke up, Miyuki, also awake, puffed her cheeks and said, "Yugen-san, you're so unfair!" Unfair? What's that about?

The day after the Nine Schools Competition mixer, Yugen holed up in his room, staring at his terminal's monitor. It displayed performance predictions, factoring in No-Head Dragon's sabotage. The path to overall victory was significantly better than in the original story.

Though tasked with assisting the tech staff, a first-year like me can't meddle in the main event. But if Mori, who learned that running technique from Mika, uses it beyond the regulation limit, it puts pressure on Ami and Keiko Kobayakawa in the women's Battle Board to win. That, in turn, burdens Miyuki.

Battle Board, Monolith Code, and Mirage Bat carry risks of contact or falling. If we clear these, the rest—where direct attacks are banned—should be manageable.

(Guess I'll play every card I've got.)

Yugen sent an email from his terminal, closed his eyes to focus, and confirmed a completed sequence. Unlike Tatsuya, who works solely with a keyboard, Yugen used brainwave assistance to build the activation sequence swiftly.

As it finished, a knock sounded. Opening the door, Yugen saw Toya and Ami.

"Sorry to interrupt your practice time," Toya said.

"No worries," Yugen replied. "It's for you, right, senpai?"

"Sharp as ever," Toya said, gesturing to the monitor. "Take a look."

Yugen showed the activation sequence. Ami's eyes widened—she'd never seen such a running technique sequence. Neither had Toya. If successful, it could theoretically block interference from other competitors.

"When did you develop this?" Ami asked.

"The concept was ready during training," Yugen said. "But I hesitated, as it might end up in the Magic Index. Too risky."

"So, you'd reject registration?" Toya asked.

They both recalled April's Blanche incident, where someone tried hacking the university's library database. Though details were hushed, security was tightened. Still, there was a chance Frizscalv could be exploited.

"As a member of the Ten Master Clans, it's ironic to say, but pride doesn't feed you," Yugen said.

"Straight to the point," Ami remarked.

"We're magicians, but still human—not transcendent sages," Yugen added.

He planned to reject all registration requests for his custom magic. If pressed, he'd impose strict usage limits, like rewriting the psion consumption to match ten Gram Demolition shots. It's less "rewriting" and more "reverting" to modern magic standards, but he kept that quiet.

"I don't live for glory," Yugen said. "With practice times, we're nearly guaranteed to pass the qualifiers. This sequence is for the finals; I've prepped twenty interference sequences for the semifinals."

"Toya," Ami said, "isn't Yugen a bit too extraordinary?"

"Knockout in under three counts," Toya agreed.

Ignoring their banter, Yugen addressed Ami. "If you adopt this, I'll prep a compatible CAD. I can talk to Ichihara-senpai if needed."

"I'll handle that myself," Ami said. "But asking an engineer to adjust another CAD now…"

"I'll do it," Yugen offered.

He knew relying on others for CAD maintenance was unwise, so he'd mastered manual adjustments. Connecting a CAD like Ami's to his terminal, he began installing, using her psion wave data for personalization.

"Those sequences are salvaged from ones Mika-neesan never used," Yugen explained. "She gave me the data."

Mika's style was to outpace rivals with raw speed, using Blitz Road for support, leaving other sequences unused. Yugen optimized them for Ami, a secret he and Mika kept.

For that sequence countermeasure, Yugen planned to deploy the Silver Blossom series in Battle Board's semifinals, third-place match, and finals. Against SB (Spiritual Being) magic like Electronic Silkworm, software countermeasures were nearly impossible, so he targeted hardware. The CAD's core response stone and processing circuits were modified to detect unauthorized psion signals or SB magic, routing them to an empty memory (registered as temporary processing storage).

A Psion Selector hardware function triggered specific actions for unregistered psion waves, acting as a security feature within regulations, doubling as a performance limiter. No lies there. When the user activates it, the circuit and memory stay off, rendering Electronic Silkworm's interference useless.

Post-check, clearing the memory takes a minute. All terminals had Electronic Silkworm deletion and protection measures, a perk of Yugen's FLT shareholder and magic engineer status.

For Keiko, Suzune confirmed no extra burden was needed, as she'd use Silver Blossom in the semifinals and beyond. Practice feedback was positive.

With the sequence installed, Yugen disconnected the CAD and stood. "Let's head to the work vehicle."

"Sure," Ami said. "Toya?"

"Hmm?" Toya noticed a Cloud Ball racket by the desk. "What's that?"

"It's a racket-integrated CAD from FLT for Kirihara-senpai," Yugen said. "Only he and his engineer know. Keep it secret."

"Is it legal?" Toya asked.

It was. Cloud Ball rules required returning the ball with a racket or magic, a practical limit due to the high skill needed to cast magic during a swing. With up to nine balls in play, the rule prevented accidental attacks. A racket-integrated CAD complied if it physically or magically returned the ball, as confirmed with the organizers and tested by Kirihara.

A switch on the racket activated a barrier spell tailored to Kirihara's traits, with psion consumption low enough to avoid depletion even in full matches. Practice matches against Shizuku, Mika, and Mayumi—all undefeated Cloud Ball champions—were grueling for Kirihara, who later got teased by Sayaka, sparking envy among the guys.

"You're a rookie competitor and an engineer's assistant," Toya said. "The opposite of Mika-senpai."

"I won't deny it," Yugen said. "Let's go."

At the work vehicle, other tech staff were busy, but Tatsuya and Kei's adjustment machine was free. Yugen used it, leaving Toya and Ami stunned. While Tatsuya was faster with traditional methods, Yugen's approach—integrating psion wave data with the OS—was unorthodox but effective, maximizing personalization.

Ami, having seen Tatsuya's CAD adjustments at the selection meeting, recognized Yugen's speed as comparable, his talent extending beyond magic. Kei watched, impressed.

"He's incredible," Kei said. "A competitor and engineer? Rare. Did you know, Tatsuya?"

"Yeah," Tatsuya replied. "He's tuned my CAD before."

It was more hardware updates and tuning, but Tatsuya kept it vague. Kei noted Yugen's support stabilized performances but couldn't demand he juggle both roles. Mika's experience—skipping mixers to adjust CADs, delegating greetings—taught her to drill CAD skills into Kei and Azusa, stressing their importance to third-years. Her refusal to complain lingered post-graduation.

Hearing of Yugen's superior skills as a first-year, Kei felt reassured.

"Done," Yugen said. "How is it?"

"Amazing," Ami replied. "Like an extension of my body. Can you tune mine too?"

"Sure, I have your data."

Later, Mayumi begged Yugen to tune hers, earning a scolding from Mori but getting the adjustment anyway.
