The next morning, Iruma opened his eyes slowly, the faintest smile resting on his lips. The room was quiet—until a loud, familiar voice shattered the silence.
"Good morning, Iruma-kun!"
Sullivan burst into the room with boundless energy, grinning ear to ear.
"Let's eat breakfast together!"
Iruma sat up, brushing his hair back with one hand. His voice was calm, a little rough from sleep.
"...Sure. I'm coming."
Sullivan beamed and leaned closer.
"Did you sleep well?"
Iruma gave a small nod.
"Yeah. Thanks, Grandpa."
Sullivan froze, then suddenly started bouncing around the room like a jelly, shouting with joy.
"My grandson called me Grandpa!"
"I must take a picture!"
He clapped his hands together, summoning a cat-eared demon with fiery orange-red hair, holding a camera.
"Smile, please!"
Click.
Click.
Then Sullivan stepped back, wiping a joyful tear.
"Iruma-kun… today is your first day at school."
Iruma stood up, tying the cloak around his shoulders. His voice was low, determined.
"I know. I won't waste it."
Sullivan pouted, dramatically bouncing around Iruma in circles like an overexcited slime ball.
"Grandson, don't be like this!" he whined, flapping his sleeves like wings.
"Why is your voice so cold? You should be melting your Grandpa's heart, not freezing it!"
Iruma exhaled softly, a twitch of amusement at the corner of his lips.
"I'm not cold. You're just loud."
"So cruel!" Sullivan wailed, clutching his chest in theatrical despair.
"I raised such a cool, quiet grandson… I'm so proud—yet emotionally devastated!"
Suddenly, Sullivan clapped his hands twice. The doors opened, and Opera stepped in with perfect timing, holding a neatly folded set of new clothes draped over their arm.
"Here are the clothes you requested, Lord Sullivan," Opera said calmly, eyes flicking to Iruma.
"Tailored to your grandson's measurements. Dark blue tones, as requested."
Sullivan's eyes sparkled.
"Tadaa! Iruma-kun, your new school outfit! A gift to match your mysterious aura and devastating charm!"
Opera raised an eyebrow.
"...You mean 'stoic intimidation,' not charm."
"Same thing!" Sullivan chirped.
Iruma stepped closer, taking the outfit into his hands.
The Outfit:
The cloak was the first thing he noticed — a flowing, deep indigo mantle with a high collar and silver trim. It hung long down to his calves, slightly torn at the edges for ease of movement and dramatic effect. The inside lining shimmered with faint starlight blue when the fabric moved.
Beneath it was a fitted combat uniform, made of dark navy material with light armor padding along the shoulders and ribs — sleek, silent, and durable. A symbol resembling a crescent moon merged with a flame had been stitched on the left sleeve, a subtle nod to both Iruma's origin and the power within.
The shirt was long-sleeved with fingerless black gloves, and the pants were flexible shinobi-style, tucked into black combat boots lined with reinforced soles.
A black sheath lay across the back of the folded set — it housed a slender katana scabbard with a midnight-blue hilt and silver wrapping, balanced for speed and precision. The sword hummed faintly, as if resonating with Iruma the moment he touched it.
---
Iruma held up the cloak, running a hand across the fabric.
His eyes softened for a second.
"…You really thought this through."
Sullivan grinned, hands on his hips.
"Of course! If my grandson is going to shock the entire Netherworld, he should at least look drop-dead heroic doing it!"
Opera crossed their arms.
"A good look. Intimidating, but clean."
Iruma nodded once, folding the cloak over his arm.
"Thanks. I'll wear it today."
With joy in his heart, Iruma sincerely thanked Sullivan, which made Sullivan even happier.
A few moments later, Iruma was heading to school, his bag slung over one shoulder. His sword rested hidden beneath his indigo cloak.
Sullivan waved goodbye with both hands, calling out cheerfully,
"Be safe, Iruma-kun! My darling grandson!"
Iruma continued walking, calm and quiet.
---
"Sigh..."
Opera watched Iruma walk off before glancing at the beaming Sullivan.
"Honestly... what am I going to do with you?" Opera muttered, arms crossed.
"You could've adopted any number of demons. So why... a human?"
"You do realize this will only cause more problems, don't you?"
Sullivan, completely unfazed, placed a hand over his heart and answered with a wide, innocent smile.
"Hmm? No reason, really."
"It's just... humans are cuter."
"I should upload that photo to the Website. I must show it to the other 13 Crowns!"
A puff of steam playfully escaped his nose as he daydreamed about his granson picture .
Opera's expression didn't change.
"No."
Without hesitation, he grabbed Sullivan firmly by the shoulder.
"You have work to do."
"Now."
And with Opera escorted the still-dreaming Sullivan back toward the mansion.

Shine~
"Good morning, Iruma-sama!"
Asmodeus sparkled with radiant energy, his eyes full of admiration and unwavering loyalty.
Iruma blinked, slightly tilting his head.
"Hm? Ah... yes, yes. Good morning, As...mo...deus-kun?"
He said it slowly, just a bit off, like someone unfamiliar with formal names.
Asmodeus gently corrected him, kneeling on one knee with pride.
"You may call me Azz, Iruma-sama. And please—allow me to carry your bag."
The classroom stirred with whispers and awe.
"So cool…"
"That's Asmodeus kneeling… again!"
"Iruma's got .... today…"
Iruma exhaled softly, brushing the edge of his cloak back.
"That's unnecessary, Azz. You don't have to kneel."
Asmodeus stood with practiced grace, falling into step beside him.
"As you wish. By the way, Iruma-sama—today is the summoning test."
Iruma gave a subtle nod, listening intently. His eyes sharpened just a little as he thought.
Summoning test... huh. Like summoning jutsu back then? I wonder if it's the same principle.
---
As they entered the classroom, all eyes turned to them. Whispers rippled through the room like a breeze before a storm.
Ba-dum.
Asmodeus stepped forward with commanding presence.
"Move aside. Make way for Iruma-sama."
The students, startled by his intensity, instinctively parted to clear a path. Iruma and Asmodeus walked straight to the front row.
Iruma glanced around, quietly amazed.
So this is the summoning test...
His eyes narrowed slightly, a subtle smirk tugging at his lips.
If demon summoning doesn't work... I'll just summon the ninja way.
Suddenly—BANG!
The classroom door slammed open, echoing with force. A powerful aura swept through the room as the teacher entered.
Step. Step.
The atmosphere turned heavy.
"I am today's administrator... Naberius Kalego," he said, his voice sharp and cold.
A few students whispered behind trembling hands,
"Isn't that the teacher who slammed a student on the first day?"
Kalego's eyes flashed.
"Huh? Who said that?"
His glare silenced the room instantly, aura flaring with authority.
A smirk curled at the edge of his mouth.
"Let me make one thing clear—if any of you fail to perform properly today, you'll be expelled on the spot."
He walked forward, cold and steady, his eyes scanning the students—until they briefly landed on Iruma.
Without stopping, he muttered darkly,
"We don't need another 'rational troublemaker' around here."
And just like that, he walked past them, cloak billowing slightly behind him.
The room was thick with tension. Students stiffened in their seats, the weight of Kalego's threat looming in the air like a storm cloud.
"You will now summon your familiar," Kalego announced, his voice cold and precise.
"The creature you forge a pact with today will serve as a symbol of your control and potential. Fail—"
His gaze sliced through the room.
"—and you'll be dismissed from Babyls before you can say your own name."
One by one, students were called to the front. Each stood before a summoning circle drawn on the floor with ancient demonic runes.
Asmodeus leaned in close to Iruma.
"It's simple. Just channel your demonic energy into the circle, and the pact begins."
Iruma narrowed his eyes at the circle.
Demonic energy, huh... Not something I can exactly control.
His fingers twitched slightly beneath his cloak.
But lets try it...if this is the same one as summoning jutsu....
Asmodeus stepped forward, head held high, a proud fire burning in his violet eyes. The room was silent—everyone knew something dramatic was about to happen.
He paused only for a second, turning his head to look at Iruma.
"Please watch closely, Iruma-sama," he said, voice calm but filled with resolve.
"I will prove myself worthy as your Servent."
Without hesitation, he raised his hand and made a shallow cut across his finger. A drop of blood fell onto the summoning circle.
"Now Burn."
With a flash of crimson light and a rush of dark energy, the room shook.
BOOM!
From the circle erupted a massive serpent—its scales shimmered like obsidian, and violet flames licked around its body. Its eyes glowed with infernal power, and a low, echoing hiss filled the air. It was a Gorgon-class serpent, its body coiled around the summoning circle with controlled, terrifying grace.
Students gasped. A few even stepped back out of instinct.
"T-that's a high-rank summon…"
"Asmodeus really is a monster..."
Asmodeus gave a small, respectful bow toward the serpent.
"You serve me now."
The snake lowered its head, accepting the pact.
Iruma, standing at the front row, watched with narrowed eyes, arms crossed beneath his cloak.
That snake... it reminds me of Aoda.
He remembered the silent, powerful serpent he once summoned as a shinobi—swift, intelligent, loyal.
But something tugged at his thoughts.
I don't have the chakra reserves for a full Susanoo yet… Only the skeletal arm. I'll need aerial coverage if things go bad.
His eyes glanced toward the summoning circle.
A crow… or maybe an eagle. Fast,i want to summon that can fly, and perfect for journeyt and escape. That might be what I need right now.
Iruma's lips curved into a faint smirk as he started forming a new plan.
He stepped forward when his name was called.
Some students whispered again.
"Wait, is that really Honor student Iruma? He looks way too cool now..."
"He's walking like...He is the boss here"
Iruma stood in front of the summoning circle. His cloak swayed gently as he raised a single hand, calm and calculating.
Kalego's eyes narrowed.
"Let's see what kind of mess you'll cause this time, Iruma Suzuki."
Then bite his finger and go into summoning circle ... and Touch the piece of paper.
And then he burn that paper, when he burn the paper light glow extrmely and it given wave also . Asmodesu was amazed and prasing iruma sama.
A shockwave burst from the circle.
BOOM!
Smoke erupted, and the room fell dead silent.
As the mist cleared... standing there was—
Kalego.
Kalego blinked, arms crossed, looking as confused as he was deeply annoyed.
"...What."
The class erupted into chaos.
"He... summoned the teacher?!"
"How?! Is that even possible?!"
Kalego's brow twitched.
"You—how dare you summon me —!"
But before he could begin his usual furious rant, a soft caw echoed from the dispersing smoke.
The room froze.
Kalego stopped mid-shout, stunned as he locked eyes with the familiar spirit now perched beside Iruma.
Asmodeus gasped, voice trembling with awe and confusion.
"I-Iruma-sama... is that... Professor Kalego?!"
The crow flapped its wings irritably.
"You insolent brat! Not again!"
Iruma simply stared, hands in his pockets, eyes half-lidded and unamused.
"Tch. Guess I missed the target."
From the summoning circle, a new shape emerged—a sleek, graceful crow, cloaked in deep violet feathers that shimmered with magical light. Its crimson eyes glowed with eerie intelligence. With a single beat of its wings, it landed gently on Iruma's shoulder. Because kalego was force to.
He glanced sideways at the crow-form Kalego, voice cold and dry.
"Though honestly... this form suits your personality."
The crow puffed up, visibly offended.
"I am not your familiar. I am a high-ranking demon and your teacher—"
"—And yet," Iruma cut in, voice sharper now, "you're perched like a bird."
He tilted his head slightly, Sharingan flickering faintly beneath his calm gaze.
"Looks like the contract sealed itself."
Kalego flapped his wings furiously, clearly trying to fight the bond—but the summoning circle glowed beneath him in response, reinforcing the magical tether.
A student in the back whispered in shock:
"A... a magnificent summon. He turned a teacher into his familiar?!"
Kalego turned his head toward Iruma with sheer disbelief.
"And why the hell am I a crow?!"
Iruma turned to him, calm and cool.
"Sorry, Teacher . Maybe your aura's just that easy to pull in."
Then, with a slow, taunting smirk:
"Next time, I'll aim for something stronger."
Kalego's eyebrow twitched again, rage building.
"You insolent—!"
Asmodeus, both terrified and deeply impressed, whispered,
"Iruma-sama... that crow—our teacher... that's magnificent. I am so Moved now."
Iruma looked over at the creature again.
The crow fluffed its wings and sat proudly, its sharp eyes scanning the classroom.
Good. Speed. Flight. Vision. Tactical advantage.
Iruma nodded slightly to himself.
"I'll call you... Karasu."
"You will call me Teacher," the crow snapped back, eyes blazing.
"Now cancel this summoning—immediately—or else."
Iruma shrugged with a smirk.
"Okay, okay, Teacher . You're no fun."
---
SLAM.
The door flung open as Kalego stormed in, dragging Iruma by the collar like a sack of potatoes.
"Lord Sullivan. Fix. This. Now."
Iruma, completely unbothered, kept his hands in his pockets, eyes half-lidded.
"You didn't need to drag me. I can walk, you know."
Sullivan spun around in his chair with a twinkle in his eye.
"Ooh~ Iruma-kun! You already completed your summoning? That was fast!"
"He summoned me!" Kalego growled, feathers still ruffled from his recent crow-form.
"And worse, I transformed into some avian mockery!"
Sullivan nodded thoughtfully, stroking his mustache.
"Yes, yes. I heard! A beautiful purple crow, right? Very majestic. Matches your personality quite well, I'd say~"
Kalego seethed.
"Cancel the summoning. Now."
Iruma stayed silent, leaning against the wall, only glancing over with a mild expression.
Sullivan smiled warmly.
"Ah, about that..."
He clasped his hands together with a sparkle in his eye.
"Since the summoning contract was properly sealed... I'm afraid it's irrevocable for one whole year!"
"WHAT?!" Kalego shouted, wings puffing slightly in rage.
Iruma raised an eyebrow.
"So you're saying... he's officially my familiar?"
Sullivan gave an innocent giggle, nodding proudly.
"Yes, my dear grandson! Congratulations on summoning such a rare and powerful being!"
"I am NOT his familiar!" Kalego barked.
"But you are" Iruma's voice was quiet, calm, with just a slight edge of sarcasm.
Kalego turned to Sullivan, desperate.
"Surely there's some clause, some spell, something—"
Sullivan floated closer and placed a gentle hand on Kalego's shoulder.
"Nope. Magic contracts are sacred. One year. No exceptions~"
Iruma let out a quiet hn, his smirk hidden just beneath the surface.
"Guess we're stuck together, Karasu-sensei."
With smirk and laughing along side with his grandpa , and kalego just watch them with smirk mark on his forehead .
