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

Kokoeji Temple lies a ten-minute walk from the Shiba household, though magic hastens the journey. At Tatsuya's request, Yugen removes Miyuki's roller skates and ascends the temple steps beside her, trailing Tatsuya. From within the temple, a booming voice echoes.

(Weapons, huh? Not real swords, I hope.)

Wooden blades clash, their sound softer than the old man's thrown bokken, which could multiply into a hundred maybe ten thousand in a blur of mass-infused strikes, a feat only he could manage.

Yugen's sense of normalcy, warped by Shin'inryu swordsmanship, terrifies him. His past life's values are gone, reduced to nothing good or bad.

Inside the temple grounds, Tatsuya spars with monks who seem more like warrior monks. Unarmed, he faces fists and wooden swords, a scene straight out of a bygone era. Yet Tatsuya deflects their blows without complaint, facing Kokoeji's disciples with calm precision.

Yugen recognizes this as "total engagement" training. In Shin'inryu, the number and skill of opponents scale with the fighter's prowess. At his own instructor evaluation, Yugen faced eighty opponents, from peers to masters. A friend once called it a "humanity graduation exam," a phrase Yugen still doesn't quite grasp.

"From their movements, Tatsuya's facing mid-tier opponents," Yugen observes.

"You can tell their skill just by watching?" Miyuki asks, eyes wide.

"Training taught me to read stances and movements. Tatsuya's impressive, holding his own against mid-tiers at our age."

A presence stirs behind them, lacking hostility. Yugen ignores it, but it speaks, voice coming from Miyuki's left. She turns, finding no one. Yugen steps in.

"Miyuki, it's the right."

"What? Right?" She spins, yelping as a finger grazes her cheek.

Regaining composure, Miyuki glares at the culprit a bald monk. "Sensei! Stop sneaking up like that!"

"I'm a shinobi. Hiding my presence is like breathing," the man replies.

"No one's a 'ninja' anymore," Miyuki retorts.

The man, Kokoe Yakumo, clicks his tongue. "Not ninja shinobi. A true practitioner of ninjutsu, not some pre-modern spy."

Miyuki sighs, exasperated. "I know you use ancient magic, but why—"

Yakumo's evasiveness is pure shinobi. Miyuki relents, her sigh heavy with resignation. His gaze shifts to Yugen.

"You must be the one staying with them, right?" Yakumo asks.

"Yes. Yugen Mitsuya. This is Kokoe Yakumo-sensei, correct?" Yugen says, bowing.

"Call me sensei. I'm the temple's abbot, teaching Tatsuya and Miyuki martial arts. A quirky monk, you could say. Mitsuya, huh? Quite a connection."

"You know Yugen's family?" Miyuki asks, curious.

"More their extended ties," Yakumo says, dodging specifics. His eyes linger on Miyuki's uniform. "First High's uniform, fresh from the entrance ceremony?"

"Yes, we came to report my enrollment and introduce Yugen," Miyuki replies, faltering under Yakumo's stare.

(This guy's no ascetic. More like a lecherous monk.)

Yakumo's gaze intensifies. "Lovely. That fresh uniform, pure yet alluring—"

Miyuki freezes, visibly unnerved. To any onlooker, Yakumo resembles a predator eyeing a schoolgirl. Yugen's patience thins; Tatsuya's earlier request to intervene looms large.

"A budding flower, a sprouting bud pure moe!" Yakumo exclaims, hands twitching.

Before he finishes, Yakumo's expression shifts. He ducks, sensing danger. Miyuki, startled, looks for Tatsuya, but he's still sparring. Her gaze lands on Yugen, his left hand raised, face a mix of exasperation and anger.

"Sensei, good thing you're bald. Hair would've been sliced off," Yugen says, lowering his hand.

"Impressive restraint, Yugen. No killing intent, either. Testing me?" Yakumo asks, standing.

"No hobby for gore in front of Miyuki. But you were testing me."

Miyuki blinks, confused. Yakumo slaps his head, grinning. "I'm a shinobi. I investigate those with ties like yours, Yugen Mitsuya, third son of the Mitsuya, once Yugen Nagano, grandson of Gozo Ueyama, Shin'inryu master instructor. Correct?"

"Mostly. I was granted master status upon high school entry, though I'll stay an instructor until graduation. But, Sensei, 'good luck' from here."

"What's that—" Yakumo starts, then pivots, raising his arm as Tatsuya's hand-chop descends.

"Sensei, I told you not to scare Miyuki," Tatsuya says, voice firm.

Yakumo laughs, engaging Tatsuya in a spar. "Nice move, taking my back!"

They fight, keeping distance from Miyuki. Yakumo's earlier jest was a test of Yugen's skill, though Yugen's restraint spared him a gruesome fate. The disciples watch, absorbing their master's techniques, a hallmark of ancient martial arts.

"When did you start training like this?" Miyuki asks Yugen.

"October of first year. Tatsuya was sore about losing to me. You?"

"July of third grade. I got my instructor certification by July of first year, just before we met."

"Five years to instructor? Incredible," Miyuki says.

Yugen shrugs. His reincarnation helped, but his grandfather's brutal training spanning decades' worth in five years was key. When reminiscing, his brother Mototsugu's shock revealed the intensity. Grandfather's excuse? "You were so eager, I got carried away." Sister Shizuru's scolding followed.

Still, Yugen holds no regrets. Probably.

"I might not beat you in pure martial arts anymore," Yakumo calls to Tatsuya, mid-spar.

Tatsuya charges, blending physical strikes with self-acceleration magic. Yakumo counters with defensive spells and subtle ninjutsu, exploiting Tatsuya's limited five-step spell-casting. Using Yotsuba clan techniques before disciples would be reckless.

(No Flash Cast in front of them, huh? Ruthless.)

Yugen sees Yakumo's skill transcends his lecherous facade.

Sweaty but composed, Yakumo stands as Tatsuya lies sprawled on the ground. Miyuki kneels, wiping Tatsuya's sweat with a towel, heedless of her skirt's dirt. Tatsuya takes the towel, sitting up.

"Thanks, Miyuki. Your skirt's dirty."

"Don't worry," she replies, standing. Activating her CAD, a magic circle forms, cleansing their clothes of dust.

Modern mages use CADs devices converting psionic signals into magical sequences replacing wands or grimoires. Talent and psion reserves are genetic, but Yugen, reincarnated, experimented with boosting his psion capacity. By flooding his mind with information, including anime and manga knowledge, he increased his reserves. His reincarnation perk converting concepts into spells streamlined this.

Daily magical training, like an athlete's regimen, honed his skills. Rest days, physical exercise, and balanced nutrition supported growth. Recreating fictional techniques further sharpened his magic, a method later adopted by his family, becoming a Mitsuya clan secret rivaling their Speed Loader tech.

At breakfast, Tatsuya, Yakumo, and Yugen eat sandwiches on the veranda. Miyuki serves tea, bustling with care. Yakumo, wiping his hands, smirks.

"Martial arts alone, I might lose to you, Tatsuya."

Miyuki beams, but Tatsuya frowns. "You blocked my strikes and dominated me. Hardly a win."

"True, but I'm your master, fighting on my terms. Losing ground to a half-trained student? I'd lose my disciples," Yakumo teases.

"Accept the praise, Brother. A little pride won't hurt," Miyuki says.

Yugen nods. "He's saying you forced him to use magic. That's high praise. Laughing arrogantly isn't your style, though."

"That'd make me a jerk," Tatsuya mutters. "But, Sensei, why dodge Yugen's strike instead of blocking?"

Yakumo glances at Yugen, who nods. "His hand-chop wasn't just a strike it was a blade. Even my defensive magic couldn't stop it. He held back, thankfully."

"Related to his martial arts?" Tatsuya asks.

"Shin'inryu's Kokoha technique turns will into a blade. I can't say more ancient magic secrets," Yakumo says.

Yugen grins. "More, and I'd send you on an Eizan pilgrimage."

"No prying, then," Yakumo laughs.

Yugen's Kokoha, an instinctive spell, became a Shin'inryu secret too potent for the Ueyama family alone. His grandfather entrusted it to an ancient magic master.

"Even without Kokoha, Yugen could flip my game," Yakumo adds.

"I'd use martial arts if needed," Yugen replies.

"Trained by Gozo himself, who even I studied under briefly. Getting close to you? I'd be in the dirt," Yakumo admits, scratching his head.
