Heroine-Saving System: Reborn In A Third-Rate Manga As The Protagonist-Chapter 76: Sex Ed [I]
The dining table at Star Mansion was a little bit lively... especially because of Reona and Yuu, both little sisters were talking to each other despite Yuu being a bit younger than Reona and not only that but the girls were even speaking with Nami.
Everyone seemed to be having a bit of fun except Victoria.
She glared at the woman who sat at the head of the table... This Hakai person, she was the one that wanted to kill them and Koya had married her to save them from any issues in the future.
Despite the woman repressing her presence, Victoria could still feel how strong she was and couldn’t help but gulp.
’I’m weak... that’s why Hubby needed to save us.’ She bit her lip and looked down at her food. She was worried... he was running an "errand" or so Hakai had told them but Victoria had a feeling that it was something much more serious than that.
Hakai took another bite of the fried chicken at her table and a maid dabbed at her face with a napkin, wiping the oil from her chin.
’It’s midnight.’ She thought.
The tracker showed the mask heading away from the venue with the transport she’d provided. ’Did he manage to do it?’
She had made Bobby give him two choices: Either infiltrate by acting as a low-tier noble or as a server. A server would be pretty hard to pull off because Saeko was actively trying to avoid assassination, so naturally it would be extremely difficult to make her accept poisoned food or drink.
Then her phone vibrated and she smiled. It was time to check it out and one of her own agents... Marina, who headed the catering team where she’d placed him, was someone she liked to call "Disguise Master."
Despite the woman not being in the Top Ten and having lower mana than the average blue-liner, she was a master of disguises and adapting to roles seamlessly.
If Koya failed to finish the mission, Marina would complete it instead and Hakai would place her grumpy husband in bed and... well, she had plans.
Marina was also the one who’d transmitted the video of Koya using Blood magic directly to her. The woman’s eyes were special after all... they could record everything she saw.
Now Hakai put her phone in landscape mode and tapped the airpod in her ear, focusing on Marina who had just started transmitting live footage.
...
The council members were talking amongst themselves, their concerned voices rising.
"Saeko hasn’t returned yet," one of them said nervously. "Should we check on her?"
A bald-headed middle-aged man stood up abruptly, his chair scraping loudly against the floor. He was heavyset, wearing the crest of the Transportation Guild prominently.
"I’ll go check her study myself. Guards, with me."
Marina walked over to the man with a respectful bow. "Excuse me, sir. One of our servers...Tenji is also missing. I hope it wouldn’t be too much trouble if I tagged along to search for him?"
The man gave her a long once-over, his eyes lingering inappropriately on her figure then he bellowed out in laughter. "Sure, sure! A pretty thing like you can come along."
Together they ascended the grand staircase. The man walked beside Marina, pointing to several rooms as they passed.
"That’s the guest quarters, that’s the trophy room, that’s—" He leaned over deliberately, his eyes fixed on Marina’s backside then his hand reached out and grabbed it.
Marina trembled but didn’t pull away.
"Wonderful shape," he commented with a lecherous grin. "Do you have a boyfriend?"
Marina nodded silently, her face carefully neutral as she looked to the ground.
The man’s grin widened. "How unfortunate would it be if your boyfriend suddenly lost his job over something as simple as... refusing hospitality?"
He leaned closer and his breath reeked of wine. "Follow me to my hotel tonight. I’ll make it worth your while."
Marina nodded again, adding just the right amount of fear to her expression. "Y-yes, sir."
’Disgusting pig,’ she thought while maintaining her trembling act. ’Men like you are why I enjoy working for a female boss.’
They reached the door to Saeko’s private study. The bodyguards that were meant to be stationed outside was missing... odd, but perhaps they’d gone inside to check on her.
The Transportation Guild head opened the door and his jaw went slack as horror painted itself across his face in real-time.
Marina’s eyes caught everything, transmitting it directly to Hakai’s phone.
The study was a nightmare brought to life.
The bodyguards’ bodies were barely recognizable as human anymore. Their arms and legs had been severed cleanly and arranged along the wooden shelves like grotesque decorations in some madman’s gallery.
Their necks had been cut through so precisely that the heads sat upright on the top shelf with their eyes still open and mouths frozen in silent screams.
Their separated limbs lay scattered on the ground among their discarded weapons like broken toys.
Blood was everywhere... it painted on the walls in deliberate arcs, pooled thickly on the expensive carpet, splattered across antique furniture in patterns that suggested arterial spray.
And Saeko...
Her head had been split vertically down the middle. Both halves sat on opposite ends of her mahogany desk like horrific bookends, facing each other across the blood-soaked surface. Her naked body lay on the floor between them, positioned deliberately and arranged like a discarded puppet.
On the wall behind the desk, painted in still-wet blood, was a perfect crimson handprint, several handprints in one which made it hard to trace... the signature everyone knew belonged to Crimson Hand assassins.
One of the guards accompanying them vomited immediately, the sound wet and violent and Marina raised an eyebrow internally. ’Was he really the one who did all this? Was he really new to assassination work?’
But externally, she resumed her act perfectly. She screamed as loud as she could... a piercing, terrified shriek that drew immediate attention from everyone still at the party below.
...
Hakai closed her phone and bit her lip. For a moment she was left genuinely speechless.
’I did say he should make it look like those maniacs from Crimson Hand.’ She thought, staring at the blank screen. ’But he went completely overboard.’
The brutality was excessive and unnecessary which was the kind of theatrical violence that Crimson Hand was known for.
However, that was more than enough to vindicate Crimson Hand as the culprits and now she just had to wait for the White King to move against one of the Order’s rivals.
’I feel so proud of him,’ she realized with surprise.
He hadn’t disgraced her name at all. If anything, he’d exceeded expectations by an uncomfortable margin. Suddenly the gates of the mansion opened once again and a smaller car pulled up to the garage.
After waiting a minute or so, Koya stepped through the front door.
His face was a bit pale but otherwise he looked fine with no visible injuries and no blood on his clothes.
"Onii-chan. Are you okay...?" Reona asked immediately.
"Master." Akemi and Yuna said simultaneously.
"Koya." Victoria stood from her seat as well as Nami.
Everyone had their different ways of addressing him. He stopped to give them a small smile, though it didn’t quite reach his eyes.
"I’m fine. Just tired." He walked over to Hakai and handed her a briefcase. "Here. The errand took longer than expected. Sorry."
He looked around. "Where is my room anyway?"
"Top floor... the biggest room." Hakai pointed toward the staircase. "You can’t miss it."
He gave the girls a small wave before ascending the stairs with heavy footsteps.
Hakai waited until he was out of sight before opening the briefcase slightly. Inside, nestled in black velvet, was Saeko’s precious Indigo necklace... a side mission she’d told Bobby to relay to him. There were only five like it in the entire world and Hakai had owned four.
Now with this fifth one, she had the complete set.
The necklace was stained with dried blood.
’You sweet, sweet boy,’ Hakai thought while closing the case and licking her lips. ’Mama’s coming.’
...
About fifteen minutes later, Koya stood under the shower. There was a tub already filled with hot water but he didn’t feel like using it...
He needed cold, the freezing water hit his skin and he gradually deactivated Calm Mind, waiting for the guilt to come.
It didn’t.
The cold water kept hitting his head, soaking his hair, running down his body. He felt... nothing.
’I don’t feel bad?’ He thought as he stared forward at the marble wall. ’I just did something horrible.’
He had desecrated bodies of the dead... He’d split them apart, severed limbs, stuffed them into shelves like objects. He’d arranged them theatrically to make a spectacle of death.
It was disrespectful and wrong and yet he felt absolutely nothing about it.
He’d really thought it was Calm Mind keeping him emotionally stable but he’d turned that off and still... nothing.
「You have gained Passive Skill: Numb (-)」
「After enough murders, a killer does not feel guilt for the lives they have taken, nor for the pain they have caused. You do not feel guilt or remorse.」
’I see.’ He thought, dismissing the notification... so he was numb to killing now. ’Whatever.’
There was no point dwelling on it.
He turned off the shower, toweled his body dry, and pulled on a wool coat similar to the one Hakua had worn when she’d tried to use mind control on him.
There were two coats hanging on the wall... one was sized for him, the other with a noticeably larger chest area was presumably for Hakai.
After dressing, Koya got a proper look at the room for the first time.
It was massive and luxurious with expensive furniture, artwork on the walls, and floor-to-ceiling windows overlooking the mansion gardens. The bathroom alone was bigger than his old apartment and the bed was absolutely enormous... easily large enough for five people.
He didn’t know why anyone would need a bed that big.
Just then, the door opened and Hakai stepped inside, closing it behind her with a soft click.
’I think I actually like that girl,’ Hakai thought as she walked in.
Victoria had surprised her... Instead of being angry or confrontational, the vampire had asked Hakai for help in getting stronger as fellow wives, she’d said.
Hakai had been so impressed by the pragmatic approach that she’d immediately thrown Victoria into one of the underground training rooms and taught her how to use the holographic combat simulators... which could be adjusted to any difficulty level, even estimated White King strength.
Nobody had ever actually seen the true power of that man. He was what they called a boundless being. Hakai was certain that one release of his true aura would scatter an entire Supercity into dust. Possibly all the Supercities but she was glad Victoria wanted to train. It meant more quality time for Hakai to make Koya completely hers.
She looked at him and he looked back at her as the room was silent for a moment.
"I saw your work," she said finally.
Koya sat down on the bed with a sigh and leaned backward. "And?"
"What a bad man you are." But she was smiling.
"She ran at me naked and I accidentally cut her head in half vertically trying to defend myself, so I needed a way to salvage the whole situation and make it look intentional." Koya said it so casually, like he was describing a cooking mistake.
He tried to feel disgust at himself for talking about murder this way but it felt... normal.
"Well you certainly made it look like a Crimson Hand member did it." Hakai walked closer, studying his face. "But why was Saeko naked? Did you perhaps take advantage of her?"
Her tone shifted... People usually let power get to their heads in moments like that. They’d do things they’d never normally do and Hakai hated men who took advantage of women in situations like that.
She was a villain, not a monster.
"She was trying to use her body to bargain with me, telling me not to kill her." Koya mumbled the next part. "But I didn’t look. Not like she could compare to you though..."
He caught himself and looked at her face quickly.
Hakai seemed extremely happy with what he’d said. She walked closer and pushed her breasts against his head while patting his shoulder affectionately.
"Anyway, I’m glad you’re back safe." She let go and moved to stand in front of him. "Without a scratch too. Marina relayed an excellent performance you put on and I’m genuinely impressed."
"Marina’s working for you?" Koya asked with mild surprise.
"Of course. The whole catering team works for the Order in some capacity, but Marina is particularly important to me." Hakai said. "So if you had failed your mission, they would have spread word to the other Order members that you were a useless piece of shit feeding off their Boss’s money. You would have lost every bit of respect within the Organization."
She paused. "Which is what I wanted originally." 𝘧𝓇ℯℯ𝑤ℯ𝘣𝓃ℴ𝓋𝑒𝑙.𝑐𝘰𝑚
"What you wanted?" Koya genuinely couldn’t understand this woman’s logic. "You wanted me to fail?"
"You’re supposed to be the house husband who comes and fucks me when I’m back home tired from everything, not going on dangerous missions too." Her lips trembled but she shook her head and stared at him with those pink eyes. "But I have no complaints about your performance... so for the rest of tonight, I’ll be your tutor and I’ll educate you on the topic of sex."
She drew out a holographic screen and tapped the word "SEX" with her finger, making it glow.
"You’re aware of what sex is, right?"
"Yes. I’m not a kid." Koya said, though internally he was less confident.
People his age weren’t supposed to be just learning this, but unfortunately he was one of those people who’d died a virgin in his previous life. He’d never even had romantic encounters with women before and he didn’t have time to beat it when he was focused on working several jobs and trying to make a lot of money, so how was he actually supposed to know the practical details?
"Good. I’ll explain regardless." Hakai pulled up diagrams. "Sex is when two people engage in intimate physical contact involving penetration. The male reproductive organ..." she gestured at a diagram "... enters the female reproductive organ here. This can result in pregnancy if proper precautions aren’t taken, though in our case pregnancy is the actual goal so we won’t be using protection."
Koya’s face remained carefully neutral while Hakai continued with surprising detail.
"There are various positions... missionary, cowgirl, reverse cowgirl, doggy style, and dozens more. Each of them are at different angles of penetration and levels of intimacy. We’ll explore those practically later." She swiped to a new screen. "Now, before you have sex with a woman, you know what you must do? If the woman has had previous sexual experience... which most women nowadays have, you need to ask her what kind of sex she prefers."
Two words appeared on the screen:
HARDCORE and SOFTCORE.
"There are two main categories of sexual activity. First is hardcore, which involves rougher physical contact, faster pacing, potentially including elements like hair pulling, spanking, aggressive positioning, dirty talk, and generally higher intensity throughout." Hakai’s eyes gleamed. "Then there’s softcore... soft touches, slow movements, eye contact, gentle kissing. That’s for people who are in love and want to... meh."
She waved dismissively, clearly uninterested in explaining further. "Hardcore is better. Both participants get on the bed and finish as intensely as possible."
The holographic screen disappeared and she looked at his slightly flushed face.
"Our first official lesson today will be kissing. You and Pale already shared a kiss, but I’ll teach you about kissing properly." She sat down on the bed beside him, close enough that their thighs touched.
The contact sent a small thrill through her that she carefully ignored. "What matters most is your positioning and intent. Place your hand somewhere meaningful... somewhere that communicates what you want."
She demonstrated by placing her hand deliberately on his thigh, letting it rest there with gentle pressure.
"There are two different kinds of kisses you should master. The first is a simple lip-press which involves closed mouths and gentle pressure and it’s usually brief. That’s for greeting someone or showing casual affection without sexual escalation." She shifted even closer, her shoulder pressing against his. "The second is a proper kiss with tongue involvement, which is what we’ll be practicing tonight. When our lips connect, open your mouth slightly. Not too wide... you’re not trying to eat my face. Just enough to let our tongues meet. Follow my lead at first, then you can take initiative once you understand the rhythm."
Hakai leaned in and pressed her lips to his.
Koya was sloppy at first, he was giving off too much pressure and uncertain timing when he was not sure where his tongue should go but Hakai guided him patiently, one hand cupping his jaw to adjust the angle.
She’d pull back slightly to give quiet corrections and then dive back in.
After several minutes, he was getting noticeably better... His timing improved and his tongue moved with more confidence, meeting hers in a rhythm that actually felt natural.
Then they progressed to deeper kissing. Hakai’s tongue explored his mouth thoroughly and she let out a small sound of pleasure.
’His saliva tastes sweet,’ she realized with delight. ’Like honey with a hint of alcohol. What the hell? Is this a genetic thing too?’
She got increasingly intoxicated by the taste and the heat building between them.
Without fully thinking about it, she swung her leg over and mounted him, pushing him backward onto the bed.
She kissed him harder now, more aggressively and tasting every part of his mouth. Her lips moved to his neck and she sucked hard on the skin there.
She honestly enjoyed the faces he was making... There was the surprise and the way his breathing changed. It was honestly breath-taking.
She bit down deliberately and left a visible hickey on his neck while his face twitched at the sensation.
Now she could feel something tenting beneath her, pressing up against her rear through the thin fabric of their coats.
It was substantial... very substantial indeed..
She looked him in the eyes with her pupils dilated. "I’m going to check your dick now."
Before he could respond, she reached down and pulled open his wool coat.
His member pushed against her ass immediately... standing fully erect and thick with visible veins along the shaft.
Hakai’s throat went completely dry as she used her eyes to measure the size visually. It was nine inches... maybe more.
"Nine...?" She whispered. "Nine inches? Jackpot, baby. JACKPOT."
She proceeded to kiss him absolutely senseless with her excitement reaching new heights.
’Our children are going to be absolutely PERFECT.’
