Chapter 215 Yamato Hina and the Demon King Medinilla ⑳*
Edited by: Kanaa-senpai
Five days had passed since the mock battle between Yamato Hina and Ise.
The royal capital, Serpentaria, was moving busily toward the recapture of the seized Fort Misone¹. They wanted to set out immediately, but preparations for food and other supplies couldn’t possibly be finished in a day or two. Although morale was rising, it seemed it would still take more time before they could march.
That aside, things were actually quite peaceful on our end. Magic Academy Viede was buzzing with talk of the “Finger Flame Burst”² I had unleashed. After all, it was a sorcery that fundamentally overturned the common sense of the craft.
Sorcery was generally considered incapable of simultaneous or successive activation. There was also the idea that you couldn’t fuse different systems of magic. In reality, those were all just assumptions. You could activate them together, and you could definitely combine them.
Several academy students came to ask how it was done, but my answer was always the same.
”Discard your rigid concepts,” I told them.
That was all I could really say. Furthermore, the students were still unable to activate the “Heat Weapon” Mihiro had constructed. This was because they couldn’t grasp the idea of augmenting the fire attribute with Augmentation magic – a fusion of the two disciplines.
Oh right, speaking of fused sorcery, there was the famous Meteor, but while it was unnecessary, the control was normally so difficult that I’d never tried using it. Even Mihiro claimed it was “too reckless.” Even Mihiro, who had the highest possibility of success, had never managed to pull it off. It wasn’t an accidental discharge; rather, the techniques themselves interfered with each other and vanished.
That great mage, saying they have no talent… That’s incredible, I thought.
Well, putting the matter of sorcery aside, Hina and Ise had apparently been scolded severely by Carmilla. Since I hadn’t said anything, it ended there, but in reality, it was a serious rule violation. In some cases, it wouldn’t have ended with just a fine. Hina seemed to be reflecting, but Ise apparently didn’t understand the gravity of it at all.
”It was to protect the Young Lady,” Ise had insisted.
If there had been a life-threatening danger, that would be one thing, but there was no way anyone could have died in that mock battle. What was he thinking?
Howeyer, perhaps because of that, the two of them started to keep their distance from me. Or rather, Ise was keeping Hina from getting close to me. On the other hand, Kagaya was actually closing the distance. It wasn’t that we were becoming friends, but she came to ask various things. Mostly about sorcery, but she also asked about the situation in Greedia.
”It would be quick if I checked with a Skill, but that’s boring,” she said. “I want to hear a live voice.”
Kagaya apparently asked Honoka and Reese various things besides me as well. I’d ordered them to keep my true identity and power hidden for now.
The problem was Yukiko. Since she recognized me as Sieben rather than Natsumi, my identity wouldn’t be exposed through her, but she was too honest. She might blurt out the truth. Actually, she had almost revealed the reason she became a monster. Since then, I’d been keeping Yukiko by my side.
Honoka looked a bit envious, though.
Well, I couldn’t just let it go without a reprimand. I decided it was time to give Yukiko her punishment.
* * *
In my private room aboard the Prydwen³, I made Yukiko get on all fours on the bed. I flipped up her skirt and pulled down her drawers. Just like her name, her backside was white as snow. I brought my hand down on her skin with all my might.
Smack!
The sharp sound echoed through the room.
”H-hyah! It hurts! It hurts!” Yukiko cried.
”Of course it does. It wouldn’t be a punishment if it didn’t hurt,” I said.
Smack! Crack!
I slapped her over and over. Her snow-white skin was turning a vivid red. By the way, I’d made sure to deactivate her Aegis⁴ effect; otherwise, the damage would have reflected back at me.
”Ouch! It hurts! Why?! Why are you hitting me?! Sieben, it hurts!”
”It’s because you were a bad girl, Yukiko,” I replied.
”Bad… girl?”
”That’s right. That’s why you’re being punished.”
She had almost told the truth about her turning into a vampire – a True Ancestor⁵. Not just that I’d made her a monster, but that I’d done the same to Sato and Suzuki. I’d glossed it over by saying they’d been bitten and I’d taken them in, but I couldn’t be sure where the leak might come from.
Smack!
”It hurrrts!”
Crack! Smack! Crack!
”Stop! Please, stop! Nnn-yah!”
It sounded like a sweet note was beginning to mix into her screams. I ignored it and kept going.
Smack! Smack! Smack!
”Ouch! Ah! Hyaa! Nn-yah!”
I slowly slid my hand between her thighs. She was already damp, her nectar beginning to overflow.
”Hey. What’s this?” I asked.
I showed her my fingers, coated in her slick juices. I rubbed my thumb and middle finger together, then pulled them apart. A thick, viscous string of fluid stretched between them.
”Yukiko, were you actually feeling good from being hit?”
”I don’t… know… I don’t kn-now… It hurts… it hurts… hah… hafun…”
”You’re definitely feeling it, aren’t you!”
Smack!
”Hee-nyah!”
I accidentally put a bit too much force into that one, but Yukiko responded with a heavy moan. This wasn’t turning out to be much of a punishment. Why was everyone around me a masochist?
Well, I’m a sadist, so it works out.
”Honestly. Yukiko, you know what happens to bad girls, right?”
”Yes… I’m sorry…”
I would have been appalled if she didn’t know how to apologize, but she knew at least that much.
”Good. Then I’ll give you your punishment. Turn your backside toward me.”
”Yes…”
Yukiko aimed her rear at me. She was a total flood, and her anus was twitching expectantly. It was obvious what she wanted. I’d gotten worked up from the spanking too, and my battle readiness was at its peak. I dropped my trousers, exposing my engorged c**k.
”You know what you have to say. Let’s hear it,” I commanded.
”Yes… Yukiko is a bad girl who didn’t listen to Sieben. So, please use your punishment to discipline her… and make her a good girl. I beg… of yew…”
She tripped over her words at the end. She was fidgeting, clearly embarrassed, but it was cute. I grabbed her by the hips from behind and moved to enter her p**sy, but then I stopped. If I did that, it wouldn’t be a punishment; she was way too ready for it. I changed my target. She likely wanted the front more, and for a real discipline, there was only one way.
Squelch.
I forced my way into her anus.
”Nngh! Ogu! H-heeee-n!”
Since I hadn’t loosened her at all, the entrance was tight, but her bowels were soft and wrapped around me.
”Ooh-hinyaaa! Sieben! There… in my butt! Ohhh! H-hie!”
”This is a punishment. You aren’t supposed to be enjoying this. Though you really are a pervert, Yukiko, getting off on your tail-hole.”
”I know! I know! Nyaaaa! Hyaaaan!”
She probably really wanted it in the front, but I’d been training her to feel pleasure in her anus too, so it wasn’t an issue.
”I believe it was… right… here!”
I thrust into her G-spot through the rectal wall. Technically, the anus doesn’t have s*xual sensation, but you can strike erogenous zones like the G-spot or the womb through the wall.
”Hie-n! It feels so good! So goooood! Ahi, hahi! Nhieeeee!”
I could make her climax just like this. Especially for someone like Yukiko, who was specifically remade for it. Honoka and Mihiro were the same way.
Slap! Splat! Splat!
I pinned her down from behind and hammered into her relentlessly. I reached around to her breasts – which had grown quite plump – and began to knead her pink n**ipss.
”N-kyaiin! My n**ipss! It feels so good! My b**bs! More! Ahin! An! Hah-hiii!”
Yukiko let out high-pitched cries. She had completely fallen into pleasure; nothing I did worked as a punishment anymore. I glanced down at her unoccupied p**sy. It was drooling with greed, as if begging for something. Fine, I’ll give it what it wants.
I pulled a vibrator out of my Item Box⁶. It was designed to mimic my own shape and size, something I used often for training. I wonder sometimes why I carry something like this, but it’s for exactly these situations.
I jammed the vibe into Yukiko’s p**sy without mercy. Her prepared canal swallowed it whole.
”Aaaaaahhh! It’s here! It’s in my p**sy! Aahn! It’s so big! Amazing! My p**sy and my butt… being dug into at the same time… it feels too goooood!”
She arched her back as the vibe hit home, climaxing violently. Her juices gushed out, drenching the bedsheets.
”Ah! Yes! Right there! It’s grinding! It’s rubbing! It feels so good! Hahi! Aheeeee!”
”Oh, is that so? It feels that good? I guess it doesn’t even have to be me, then,” I teased.
Yukiko froze for a split second, looking startled.
”N-no! I want Sieben! I want Sieben’s! Sieben’s is the best!”
”If mine is the best, that means there’s a second and third best. So you’d be fine with someone else, wouldn’t you?”
”No! That’s not it! Only Sieben! Only Sieben for me!”
”But you’re coming so hard from a vibrator.”
”That’s… that’s not true! I’m coming from Sieben’s d**k! I’m coming from yours!”
She shook her head frantically. Of course, that was a lie. She’d been coming much harder since I added the vibe.
”Man… to think you’d lie to me. I’m disappointed. I was going to forgive you if you were honest. Since you’re such a liar, I guess you’ll only ever get the vibrator during s*x from now on.”
”I’m sorry! I lied! It felt good even if it wasn’t yours!”
Talk about a quick reversal. Even if the shape was the same, nothing beat the real thing.
”I see. So you’ll just get all feel-good and come from anything that isn’t mine.”
”Yes! This p**sy will come even from something that isn’t yours! I’m sorry! I’m sorry! Please, use your punishment to re-train Yukiko’s slutty p**sy!”
”Fine. Then I’ll have to thoroughly discipline this cheating p**sy.”
With the vibe still buried in her front, I hammered into her anus with renewed violence. I moved with enough force to break her. But Yukiko is a vampire – a True Ancestor. She won’t die, and she won’t break.
”Ah! Ah! Aah! Why?! Why is it still in there?! Stop! Ah! Ah! Aaaaaah! Not the vibe! I want your d**k! I want yours! Hiee-aaaaan!”
”That’s why we’re doing this special training. So you don’t come from anyone but me. If my c**k is really the only one you need, you shouldn’t be able to come from a little vibrator.”
”That’s… impossible! No, no, no! Impoooossible! I’m sorry! I’m sorry I’m sorry I’m sorry I’m sorry! I’m going! I’m coming! I’m c**ming, I’m c**ming, I’m cumm-ing!”
SQUIRT!
She climaxed with a spectacular fountain of spray. Her body spasmed and convulsed, her eyes rolled back, and her tongue lolled out. Her v**inal walls went slack, and the vibe fell out with a wet thud. Yukiko panted heavily, lost in the afterglow, but I wasn’t finished yet.
Still connected to her, I shifted positions. I sat cross-legged and pulled her up into a seated position on top of me. I retrieved the vibe and shoved it back into her p**sy, then began to thrust upward from below.
”Nngh… oh… h-haaan! Sieben! W-wait, I just came! It’s too sensitive! No! No, no, no! I’m going again! I’m already going! I’m c**ming, I’m c**ming! Aaaaaaaah! I can’t stop c**ming! Aaaaaaaaaah! I’m going to go foreveeeer! I’m sorry, I’m going again!”
Regardless of her climaxing, I thrust without mercy. Yukiko, who had zero resistance to pleasure, ended up coming over and over again with the vibrator still buried inside her.
＊＊＊
”O… ohh… hie…”
Yukiko’s responses were getting dull. I suppose I overdid it. After that, I’d changed positions countless times and had my way with her. In the end, she’d passed out with her ass still in the air. Her stomach was bulging like a pregnant woman’s.
I slowly pulled my c**k out. A faint plop sound echoed. Her anus was still gapping open. And then…
Splurt!
The s**men I’d emptied into her bowels came gushing out like a fountain.
”Hah… Sieben… more… more good things… please… in my butt… in my p**sy… put it in…”
Even while unconscious, she was begging for more. Being invited by such a sweet voice, I couldn’t exactly refuse her.
”Nn… aahn… my d**k, the d**k! Ah! Aahn! Give me more…”
This time, I slid into her p**sy and continued to violate the unconscious Yukiko.
Honoka, Mihiro, and Reese would eventually hear about this, but the fact that I’d end up doing the same to them is a story for another time. Three days later, our preparations were finally complete, and we set out for Fort Misone.
* * *
**Side Note: How it was found out.**
”Uwa… the smell of s**men and ‘girl’ in here is insane. The bed is literally soaked in c**m and love-juice. Master, just how much did you have to do to make it like this? Washing this is going to be a nightmare,” Honoka said, looking at me with judgmental eyes.
”…………Sorry,” I replied.
Actually, Yukiko is the one who can take the most “reckless” treatment. Since she’s immortal, she repairs herself immediately even if she “breaks” a little. I could probably do limb-loss “daruma” play if I wanted to, but even if she heals, I don’t really have the stomach for it.

Summary:
Sieben reflects on recent academy events and political tensions in Serpentaria before focusing on Yukiko’s potential for revealing his identity. To ‘punish’ her for her loose lips, he engages in a prolonged and extreme session of anal and double-penetration discipline. The chapter ends with the group finally departing for Fort Misone after five days of preparation.

Trivia:
- The protagonist is currently using the name Sieben but is actually Natsumi.
- Yukiko’s Aegis skill reflects damage, meaning Sieben must turn it off to touch her roughly.
- Mihiro’s ‘Heat Weapon’ is a fusion of Augmentation and Fire magic that academy students can’t replicate.
- The setting involves a Western-style airship or ship named Prydwen.
- Yukiko is a ‘True Ancestor’ vampire, granting her near-instant regeneration.
- Ise is overprotective of Hina to the point of creating distance between her and Sieben

Character Insight:
Sieben shows a practical, albeit twisted, side by keeping Yukiko close to prevent leaks. Yukiko’s absolute submission is highlighted by her begging for more even while fainted. Honoka’s role as the grounded, chore-handling companion is reinforced.

Behind the Scenes:
The author admits to adding erotica purely due to personal ‘hunger,’ resulting in a chapter that halts plot progression for fan service.
