Chapter 148 Valentine’s Day
Edited by: Kanaa-senpai
February 14th, Valentine’s Day.
On this perfect day, Aki officially launched his counterattack.
He swept the massive hoard of chocolates gifted by girls he knew—and plenty he didn’t—straight into his personal storage dimension, then began opening the pink, heart-stamped love letters one by one.
There wasn’t much worth reading.
The contents were practically identical across the board, generally boiling down to a confession, though a few explicit ones skipped the pleasantries entirely and invited him to a straight-up hookup.
Rather than the actual text, Aki cared far more about the signatures.
”Shinomiya Natsuha…”
Staring at the two piles of love letters on his desk, which were divided as clearly as black and white, he picked an envelope out from the smaller stack.
(She really is an incredible piece of ass. I just don’t know if the butterfly effect has messed with her timeline. If that yellow-haired punk hasn’t gotten his hands on her yet, she’s absolutely worth taking.)
Shinomiya Natsuha. Class 1-F at the private Kuoh Academy¹. She had an exquisitely gorgeous, sultry face, a smoking-hot, voluptuous body, a bright personality, and was a total badass at Aikido.
In terms of raw fighting capability, your average adult male wouldn’t even be able to lay a finger on her.
Beyond all that, she also happened to be the female lead of Ajisai no Chiru Koro ni, an adult anime Aki used to keep in his private collection.
After quickly recalling the basic lore, Aki swept the rest of the small stack of love letters into his spatial storage, while the letters signed with completely unfamiliar names were instantly reduced to nothingness by his Azure Flame².
Whether he threw them in the trash or let them gather dust at home, neither option felt right.
After weighing it back and forth, completely erasing them without a trace was the cleanest way to handle it.
Looking at his spatial inventory, which was now packed to the brim, Aki let out a helpless sigh.
”Looks like I need to keep grinding my Space Magic³. A single cubic meter really doesn’t cut it.”
Ever since breaching S-Rank, he had been constantly tinkering with his pocket dimension.
Just recently, he had finally succeeded in mastering the art of opening up a mustard-seed space.
Unfortunately, he could only maintain a pocket roughly one cubic meter in size.
If he wanted to expand it, he either needed his power level to breach another threshold, or he needed a sudden stroke of enlightenment regarding Space Magic itself.
In all honesty, while Space Magic was notoriously difficult, it wasn’t actually that rare in this world.
Whether it was the teleportation magic circles Rias frequently deployed, various fixed spatial rifts, or even entirely self-contained pocket dimensions, such things were practically common knowledge here.
Sometimes, just to host a Rating Game, the Demon Kings would construct an entire temporary subspace on a whim, and live broadcasts utilized Space Magic constantly.
However, almost no one built a small, portable, localized pocket dimension just to store everyday gear the way Aki did.
Even spatial artifacts themselves were incredibly hard to come by.
Aki had actually brought this up to Rias before.
The answer he got was that normally constructed dimensions couldn’t move with the caster.
Furthermore, if an outsider managed to get the exact coordinates of a pocket dimension, they could bypass the owner and crack it wide open.
Yet, after rigorous testing, the mustard-seed space Aki created moved perfectly with his body, and no one else could open it.
Forget opening it—they couldn’t even sense its existence.
Rias and the others had tried using Aki’s exact method to open up a space of their own, but the results were identical to their old magic; they couldn’t form a truly localized, exclusive pocket dimension unique to themselves.
In the end, they could only chalk it up to Aki’s own bizarre nature.
He already had more than enough anomalies under his belt anyway, so adding one more to the list didn’t really shock anyone anymore.
Still, every perk came with a downside.
While he couldn’t speak for other applications of Space Magic yet, Aki found the actual act of expanding his dimension significantly harder than anyone else did.
Even though they were both operating at S-Rank strength and Aki was arguably more powerful than Rias, Rias could effortlessly manufacture a space the size of an entire classroom, while he still broke a sweat just maintaining a single cubic meter.

After school, Aki took Shinomiya Natsuha’s love letter in hand and walked over to Class 1-F with a smooth smile on his face.
”Shinomiya-san, good afternoon,” Aki said.
Shinomiya Natsuha was in the middle of packing up her school bag when a rich, deep male voice suddenly echoed right next to her ear. She looked up dynamically, her eyes widening.
”Uesugi-kun?!” Natsuha gasped.
”Yep, it’s me. You can just call me Aki,” Aki replied.
Aki smiled warmly, playfully waving the pink envelope between his fingers.
”I read your letter. I actually think you’re pretty great too, Natsuha. So, how about we go out on a date right now?”
”…Huh?!!!” Natsuha shrieked.
The light-purple-haired beauty stared at him with wide, rounded eyes, her cherry lips parting in a completely stunned, disbelieving shriek.
The remaining students who hadn’t left the classroom yet all looked over instantly, completely consumed by curiosity over what was going down.
Ever since Rias and Shitori Sona issued their strict warnings, coupled with the fact that Aki had basically stopped hitting on ordinary girls, the students of Kuoh Academy had mostly stopped tracking his every move.
If it weren’t for the Bitter Parent Template⁴ acting up again, and if Aki hadn’t actively suppressed his overwhelming personal charm and aura, he wouldn’t have received such an absurd mountain of love letters and chocolates this Valentine’s Day.
But the second Natsuha let out that startled cry, the students’ locked-away memories instantly came flooding back.
”Yo, isn’t that Uesugi the Great Demon King?”
”Yeah. Looks like he’s locked his sights on Shinomiya this time.”
”Damn, Shinomiya, huh? If I had the Great Demon King’s game, I wouldn’t pass her up either.”
”No kidding. Look at that chest, those legs, that face… If I weren’t terrified of her giving me a brutal shoulder throw, I would’ve confessed to her months ago.”
”Wake up and smell the coffee, man. You don’t even have the credentials to get thrown by her.”
”Uesugi the Great Demon King didn’t even come here to confess. Look at what’s in his hand. Eight times out of ten, Shinomiya threw herself at him.”
”God damn it… I’m so jealous.”
Aki had already walked so far down the path of an absolute degenerate that he was entirely immune to this kind of gossip by now.
However, Natsuha, whose romantic feelings were only just beginning to stir, couldn’t handle the heat.
As the whispers around them grew increasingly explicit, her pale, pristine face flushed a deep pink.
She lowered her head in sheer embarrassment, her highly alluring body shifting uncomfortably.
”Natsuha… I can call you that, right?” Aki asked.
Natsuha nodded blindly, her voice barely a whisper.
”Yes…”
”Natsuha, you definitely wrote this letter yourself, right?” Aki let out a bright, casual laugh, reaching forward to gently tilt the girl’s smooth, delicate chin upward. “If this is just someone else’s mean prank, I’ll take back everything I just said.”
Forced into eye contact, she looked directly into his deep, night-sky eyes, which shone with an incredibly brilliant light.
The girl’s heart began to hammer violently against her ribs completely out of her control, her light pink blush deepening into a rich crimson.
”I… I wrote it…” Natsuha stammered.
Gathering every ounce of her courage, Natsuha spoke up clearly, “I just… I never imagined Uesugi-kun would actually read it, let alone agree…”
So many girls had flooded Aki with chocolates and love letters that he obviously couldn’t accept them all face-to-face; the vast majority were stealthily crammed into his shoe locker or desk drawer.
”As long as it’s yours, that’s all that matters,” Aki said.
Aki smoothly caught the girl’s stark white wrist, his grip assertive and unyielding.
”We can sort out the finer details on our date.”
Natsuha didn’t offer a shred of resistance.
Her face completely red, she let Aki take her by the hand and lead her right out of the room.
Just before crossing the threshold, Aki caught a glimpse of the back corner of the classroom out of the corner of his eye.
A tall male student with dyed deep-yellow hair, dark skin, a naturally thuggish face, and two silver earrings was glaring daggers right at them.
By the looks of it, this yellow-haired punk hadn’t succeeded in making his move yet.
Realizing this, Aki felt a massive surge of pure amusement.
In the original timeline, Natsuha couldn’t handle her own loneliness and ended up actively giving away her virginity to this guy, starting her downward spiral down a point of no return.
Now, she was still the one taking the initiative to give herself away, but with Aki in the picture, she obviously wouldn’t settle for a complete piece of human garbage she had zero feelings for and openly loathed.
Compared to a generic yellow-haired thug like Ooshika Masaru, who slept around with anyone he could find, a remarkably handsome guy like Aki was exactly her ideal type.
As a result, a romantically restless Natsuha was mathematically guaranteed to choose Aki.
That love letter and the beautifully wrapped box of chocolates were the absolute proof of it.
”Tch, what a total slut. I wasted all that time chasing her, and the second she can’t keep her legs closed, she goes and picks a useless pretty boy,” Ooshika Masaru spat.
Watching Aki’s back recede down the hall, Ooshika Masaru expressed his anger.
”You’ve got the second-year upperclassmen covering for you inside the school walls, but once you step off campus, I’d love to see who the hell is left to save your skin.”
With his power resting at the absolute peak of S-Rank, Aki’s height and weight had scaled up slightly, bringing his current build to 177 centimeters and 75 kilograms.
However, because his bulk was comprised entirely of dense, compact muscle, he still looked remarkably lean and deceptively slender once he put his school uniform on.
Combined with that naturally submissive pretty-boy face, as long as Aki didn’t actively radiate a terrifying, murderous aura, most ordinary people would instantly write him off as a harmless, herbivorous boy.
What yellow-haired punks detested more than anything was the classic “herbivore” protagonist who wouldn’t take a girl even when she was served to him on a silver platter.
If they never ran into an actual NTR predator, they could live in peace, but the moment they crossed paths with one, they were prime real estate to become the ultimate cuckold.
