Chapter 525 Supernatural Decisive Battle ①
Edited by: Kanaa-senpai
”I still have a bit of work left today, so I’ll be calling for you very soon… ♡”
Those were the words Mother Marian had said that day, her hand heavy on my shoulder. That damp, lingering weight-it’s like I can still feel it pressing into my skin even now.
For the next few days, I was a walking ghost. Two years… over 17,520 hours. I’ve spent every waking moment tempering this body-this (flesh-hole)-and I honestly didn’t know if I could even withstand what was coming.
I rushed to Old Lady Miranda, my mentor in Magical Medicine, and begged her to brew the highest-grade stamina tonic she could manage.
My wives weren’t any more subtle; they practically force-fed me every aphrodisiac in the pantry, telling me in no uncertain terms, “Don’t you dare go limp on us.” Even the church crowd and the Elven reinforcements offered up their own versions of ‘blessings’ for the occasion.
I didn’t just rely on tonics, though.
I threw myself into the development of my ‘Ultimate Decisive Weapons’: the Stake-Driver¹ and the Zero-Type Multi-Headed Mole-Whip².
And, of course, the Ultimate Apex Slime-Pal³.
I threw shame, public opinion, and my budget out the window. I burned through high-grade mana stones and Ultra-Miniature Magic Circuits⁴ like they were candy.
With the Queen’s royal decree, I even conscripted the Court Mages to help me forge these circuits-things never meant to be used on any human body other than Marian’s.
Then, one day, while I was at the convent to check on Sister Amelia, she did it again. Marian slipped up behind me, her hand resting softly on my shoulder as she whispered into my ear.
”Say… are you free tonight… ♡?”
A violent shiver raced down my spine! I couldn’t tell if it was raw excitement or pure, unadulterated terror. Goosebumps broke out across my entire body, and yet, an unidentified power-a primal urge-surged from deep within my gut.
(Fine. Let’s do this…!)
Outwardly, I managed a steady, “Yes, of course.” I went home, packed my gear, and made every possible preparation. Once the sun had fully set, I kissed my wives and kids, told them I loved them, and left the house.
I had to shove down the gut-wrenching anxiety that I might never make it back here in one piece. Canarias Convent at night was a different beast entirely.
Sneaking into the ‘secret garden’ of the nuns under the cover of darkness should have been a romantic thrill, but I was too wired to appreciate it.
The entrance gates, usually wide open during the day, were bolted shut. Marian stood before them, draped in an aura of overwhelming, predatory sensuality.
”Hehe… I’ve been waiting for you, Shopkeeper-san ♡”
Was that the call of a demon, or the Reaper herself? Okay, maybe I’m being a bit dramatic. She was just standing there in her usual habit, radiating heat. I wondered…
(Is she still clenching that Ddo-Buddy⁵ in both her holes right now?) The mere thought made my voice crack.
”…Yes. Thank you for inviting me tonight.”
”My, aren’t we being a little formal? This isn’t a business negotiation… and that’s no way to talk to the woman you’re about to embrace, is it ♡?”
She didn’t wait for an answer. She slid forward and caught my arm. I felt the unmistakable weight of her breasts against me. There was no fabric between us-no bra, no support. I’d already confirmed she was going commando, but it seemed she’d doubled down on the lack of equipment.
I was rattled by her taking the lead, but I wouldn’t be the owner of an adult magic shop if I folded now. I stepped into her personal space, reaching out to grab a handful of her backside in a counter-offensive.
”You’re right… No, you’re right, Marian. Tonight, I’m staking my pride as a man on satisfying you and-“
”Aunh! ♡♡♡”
”-sh-showing you exactly what I can do…”
The moment my palm hit that terrifyingly lush, supple flesh, Marian let out a cry so vivid it made my head spin. To be honest, it caught me completely off guard.
I was so startled that the polite speech I’d been trying to drop came flooding back.
(With people living right nearby, how can she make a sound like that…?)
It sounded like an angel ringing a bell from the heavens. It was the kind of voice that could make a dying old man salute for one last time.
Me? Well, obviously… hearing that at point-blank range, any healthy male would be at full mast. Not that I’d been doing a great job of holding back since she pressed her chest against me, anyway.
”Hehe… you’ve got some very busy hands, don’t you… ♡? I heard the Shopkeeper was a gentleman until he got into the bedroom… ♡”
”I, uh… haha…”
Marian didn’t pull away. Instead, she let go of my arm and snuggled even closer, slipping into my personal space. She layered her hand over mine, pressing my palm even harder into the curve of her ass.
(Oh, this is bad. I can’t win against this ‘natural’ talent.)
They say the women of the Church of Demon-Subjugation all train to be more seductive than a Succubus, but she was the real deal. That pouting, upward gaze; the voice that sounded like a scolding and an invitation rolled into one; the weight of her breasts; the way she let me knead her… it was all designed to ruin a man.
People call me an ‘incubus’ sometimes, but it’s an insult to her to even put us in the same category.
”Don’t be so impatient. I’ll show you the way… ♡ Come on, let’s go ♡.”
”Ah… right.”
My momentum was shot. She led me through the night entrance of the convent. Even the places I saw every day looked different in the dark-half scary, half exhilarating, like breaking into a school at night.
But that feeling was drowned out by the presence of Marian in my arms. Even though she wasn’t holding my hand anymore, it felt like my palm was glued to her skin. I couldn’t let go.
Firm, bouncy, and incredibly thick… I could squeeze this forever and never get bored. It was a texture unlike any other ass I’d ever touched. She didn’t mind the wandering. She didn’t mind the grip.
Instead, she just let out these little, breathy moans-“Nfuh ♡,” “Nah ♡,” “Haahn ♡”-and my brain started to cook.
Marian’s expression was unreadable. She acted as if she didn’t even notice I was kneading her, walking with that same ‘boing-boing’ rhythm in her hips as always.
I still couldn’t tell if she had the Ddo-Buddy inside her. I’d been watching her like a hawk every time we met, but her movements were perfectly natural.
”Well, here we are ♡.”
”…Huh?”
Before I knew it, we’d arrived. I’d been so focused on her that I didn’t even notice where we were going.
”My bedroom ♡. Or would you have preferred the training hall where the girls are practicing right now ♡?”
”Wh-what? No, that would be…”
”Hehe, I’m just teasing ♡. It would be way too much for them… and even I’d be embarrassed by that ♡.”
Marian blushed, and my heart hammered against my ribs. (Was she doing that on purpose?) Her s*x appeal was so potent I felt like I was already caught in her web. I had no idea how many more tricks she had up her sleeve.
”Now, let’s go inside ♡. But don’t get one thing twisted… ♡”
”What?”
”This is still ‘training’ ♡. I’m going to do my absolute best to endure so I don’t lose to you ♡. So you’d better work your hardest to try and break me, okay? ♡”
”…Is that a declaration of war? I’ve got my pride as a man on the line here. If you’re going to put it that way, I’ve got no choice but to go all out.”
”Hehe… ♡ Good. Let’s make this a night to remember… ♡”
And just like that, I was lured into the den of the Succubus… no, into Mother Marian’s bedroom.

Glossary:
Notes:
• Marian – Mother Superior of the Canarias convent, an Ascetic Faction nun of the Church of Demon‑Subjugation, wears a black habit, wavy purple hair, a busty figure, a tear‑shaped mole beneath one eye and a distinctive Monroe walk. She arrives to confront Kento about the Devil’s Stick, balancing a holy façade with an intense personal obsession for the Alex‑kyun product.
• Miranda – Granny (Old Lady) Miranda, an elderly witch‑like mentor in a weathered cloak and silver hair, masters magic medicine and midwifery, subtly monitors unborn babies, and taught this art to both the protagonist and Barbara, linking them as their shared teacher.
• Amelia – Light-blue-haired Sister of the Canarias convent, once shy and saintly, now pregnant and still wearing Kento’s ring on her left finger—her blushes linger, red-tinting ears and neck, her voluptuous figure among the convent’s most prominent. She quietly manages soup kitchens and shop stock in traditional habit, her faith once drove her to seek conception, and now, with child, she remains the only sister who ever visited the protagonist for that sacred purpose, her devotion unchanged even as her body bears new life.
