Heroine-Saving System: Reborn In A Third-Rate Manga As The Protagonist-Chapter 79: Bloodline Skill

Disguise Master walked through the hallways of Star Mansion. Her face was different from the Marina disguise... this version looked colder, with brown hair instead of Marina’s softer style.

She was the head maid of Star Mansion when she wasn’t on missions.

Disguise Master hadn’t made it into the Top Ten, but she existed in her own league as a a Top 1 disguise master.

She could become anyone: girl, boy, woman, man, anything... even this face wasn’t her real one.

Only Hakai had ever seen her true face.

"Hey, did you hear?" One of the workers muttered as she passed. "Hideaki Ito, the Head of the Transportation Guild, was killed in cold blood in a hotel room yesterday. His bodyguards too."

"Yes, I saw the photos before they got taken down," another maid whispered. "Everyone suspects the Red Hall did it. I agree... it was brutal. The killer even posted it on his official account."

Disguise Master kept walking. She had killed him. That pig who’d touched her, threatened her "boyfriend’s" job, demanded she follow him to his hotel.

When he’d called her expecting compliance, she’d brutalized him and his guards. Though honestly, it couldn’t compare to what Koya had done to Saeko. That scene had been inhumane.

She reached the Master bedroom and paused with a hand on the handle.

’Boss is usually naked in the morning...’ She thought with a small blush. Since her Boss only liked men, Disguise Master never got attention but serving was enough.

She opened the door. The first thing she registered: her Boss wasn’t alone and he second was that the room looked like a warzone.

Walls and floor had palm marks bruised into them... the handprints pressed hard enough to dent the plaster.

One long mark looked like someone clawing for purchase, the furniture was destroyed... the big mirror had been shattered, the nightstand was in pieces and a chair was broken in half... there was also white liquid everywhere.

She looked at substance on the door handle, picking some between her fingers. "What’s this...?"

It was sticky, thick and slightly dried... painted across the floor, walls, sheets, even the ceiling. She brought it to her mouth cautiously and it had a sweet taste then she understood.

From where she stood, she could see her Boss’s ass barely covered by sheets. It was completely reddened, bruised, and marked several times over.

White liquid was leaking out of her onto the soaked sheets then she noticed Koya with a visible bulge still present under his covers.

She pressed a hand to her lips to prevent throwing up... Disguise Master had just tasted man cum.

She ran out and slammed the door, the sound woke them both up immediately.

"Morning..." Hakai’s voice was hoarse as she turned to Koya.

His eyes were still slightly crimson. "...Daddy~"

Hakai’s body felt totally sore. Every part felt thoroughly used... except her asshole. She’d told him she didn’t like anal, so he’d respected that. But after the first rounds... they’d gone at it for hours and he’d pounded her senseless.

He was inexperienced with positions at first, so she taught him then he dominated her completely. He’d even done a proper mating press, nearly breaking her back and the bed.

It had been the best sex of her life.

"Hey. What happened?" Koya felt splitting pain in his head. After entering her that first time, his memories blurred but he remembered being really rough and learning more positions from Hakai though he had roughed her up until his member felt sore.

He wanted to apologize, but saw her hugging his chest contentedly.

"I loved every bit of last night," she said, nuzzling him. "You were too rough though. I can’t feel my legs."

"Sure..." He looked around. "The room..."

"I’ll have maids fix it tonight." She waved it off. "Worth it."

Koya examined her... Her neck had bite marks which were dark purple hickeys and then he pulled off the covers which made it much worse.

There was reddened skin everywhere and bite marks on her breasts, stomach, thighs, and even on her ass.

Had he been an animal?

"You like your work?" She smiled. "You were set on marking me. I love it."

She tried rolling off the bed but couldn’t move. "Can you bring breakfast? And feed me? I literally can’t move."

"Sure." He got up and he was naked but there were far fewer marks on him... it was just neck hickeys and one on his chest.

He pulled on his trousers. "I’ll get it... babe."

He left.

’If I go back to silver crest power, I’ll heal instantly,’ she thought but she was teaching him aftercare, so she’d stay weakened longer. ’He does look different now though. Those crimson streaks on his hair...’

...

Koya reached the dining room. The girls were already seated... Reona, Victoria, Yuna, Akemi, and Nami were all having breakfast together at the long mahogany table.

When he arrived, most waved cheerfully and he smiled and waved back warmly.

Victoria immediately came over to hug him from the side, but her face scrunched up in confusion.

"Why do you smell... weird?" She asked, sniffing him carefully.

She hadn’t smelled this particular scent before so she didn’t immediately recognize it, but it smelled like two different people’s flesh aligning. "What were you doing all night with her?"

She’d trained hard last night, pushing herself to protect Koya better.

Though she couldn’t defeat even the Hakai projection in the training room yet, she’d come a considerable way in just one evening but if Hakai had taken advantage of him somehow, Victoria couldn’t forgive that.

"Don’t worry about it," he said while patting her head gently.

She looked up at his face and noticed his eyes first... they were crimson and not only that, but amongst his natural blonde hair, there were small streaks of crimson red here and there, like someone had painted highlights.

He looked different.

He turned to one of the maids standing at attention near the kitchen. "Can I get a breakfast plate? I need to bring one up to Hakai... she can’t walk right now."

Nami immediately spat out her drink, causing everyone at the table to look at her in surprise.

The KCAC worker blushed deeply, covering her mouth.

Koya was shirtless and he had visible hickeys all over his neck and chest plus he had the unmistakable smell of sex clinging to him. She knew that smell well... she used to live with a colleague who had sex constantly, so she was very familiar with it.

’Fuck... I found him first,’ she thought bitterly, gripping her fork so hard her knuckles turned white. ’I was the one who invested time in him. I took care of his sister. He trusted me with Reona. Why are these new women coming in and trying to take the man I’ve been cultivating this whole time? Now he’s slipping right through my fingers.’

She cleared her throat deliberately.

"Koya-kun," Nami said, looking directly at him with unusual seriousness. "You’re being a bad guardian right now."

Koya raised an eyebrow. What did she mean by that? And why was she suddenly bringing this up?

"How?" He asked.

"Your sister, Reona-chan, has Guardian Visit Day today," Nami replied pointedly.

Koya blinked. "Guardian visit day?"

Both Reona and Nami face-palmed simultaneously.

Reona stood up quickly to explain as the maid handed Koya the breakfast platter meant for Hakai.

"Onii-chan, Guardian Visit Day is when guardians come to see our teachers and observe our classroom. You can bring your papa, mama, or even your older sibling. You’re my legal guardian, so you HAVE to come." She was already dressed in her full Keropolis Middle Division uniform. "And class starts at 8:30, which gives us exactly 40 minutes..."

"I see." Koya processed this quickly.

He could speedrun feeding Hakai and then get ready so he turned to Victoria. "Do you want to come along...?"

"Y—" The word died in Victoria’s throat. She shook her head, making Koya’s eyes widen in surprise. "Not now, Hubby. I actually want to talk with Hakai privately about something."

"Oh." Koya checked her affection status mentally... there was no reduction so it was still at Maximum. While he wanted to know what had changed her mind, he was also in a hurry.

"Please stay safe then. You too, girls." He looked at everyone. "Reona, I’ll come right away. Maybe we’ll take Nami along too?"

Nami’s face flushed with color... This was her chance.

She needed to deepen her relationship with Koya before returning to this mansion full of competitive women so she needed private time with him.

...

At 8:18 AM, Nami pulled up to Keropolis Middle Division in her personal Dodge that had been driven over to Star Mansion’s garage earlier.

They would have arrived sooner if she and Koya hadn’t spent ten minutes absolutely drooling over the multiple luxury cars filling the entire garage.

Hakai had apparently gifted Koya two cars personally, though they’d need to be driven by the mansion’s butlers until he learned to drive properly.

She’d also given him something else.

Koya, now wearing a black leather jacket over a dark shirt and fitted pants, looked down at the black credit card in his hand.

He could still hear Hakai’s exhausted but satisfied voice in his head from when she’d handed it to him.

’Here, Daddy... that’s your personal spending card. It’s connected directly to my main account, so spend as much as you want. Actually, if you don’t spend at least a million crowns today, I’ll make you sleep outside tonight.’

What the hell was he supposed to use a million crowns for in one day? He stored the card in his storage ring and focused as the car pulled into the school driveway and Nami parked it smoothly.

"Alright, Reona-chan, are you ready?" Nami asked while unbuckling her seatbelt.

She was looking at Koya differently now... Before they’d left the mansion, Nami had been unfortunate enough to see exactly how Hakai currently looked.

To say the older woman had been manhandled was a severe understatement... The normally confident, powerful woman was completely sated, thoroughly marked, and barely able to move.

Nami had looked at her own body in comparison. She wasn’t as voluptuous as Hakai, not nearly as curvy or experienced.

But would Koya still handle her like that if given the chance? She loved rough men after all or at least she thought she did, she never dated someone long enough to get on the bed...

"Yes, I’m ready!" Reona replied, opening the back doors and stepping out onto the pavement.

Koya stepped out of the passenger seat. The parking lot was filling rapidly... cars pulling in everywhere and even some families arriving on foot.

The school was impressive: large three-story structure with reinforced walls, separate gymnasium and sports fields behind. It also had high security walls with guard stations surrounding everything.

A banner hung over the entrance:

[WELCOME GUARDIANS TO SCHOOLWIDE FAMILY APPRECIATION DAY]

"And what class are you in?" Koya asked Reona.

"I’m in 3-B," she said, grabbing his hand. "Onii-chan, let’s go! We’re late!"

She dragged him along and Nami followed with a smile.

...

About twenty minutes later, Koya sat on a wooden bench outside Classroom 3-B in the third-floor hallway. Upon entering the school building, they’d all been given temporary ID cards with "GUARDIAN" printed on them in bold red letters, there was a number on each card too.

Now they were waiting to be called into the classroom for observation. Apparently the process was organized... families would be introduced one at a time so it wouldn’t be chaotic, then all guardians would observe the class lesson together from seats in the back for the first half then tour the school facilities after the first class.

There were several other people lining the hallway benches as well... mostly older parents in their late thirties and forties, a handful of grandmothers and grandfathers, and several college-age older sisters.

Koya was noticeably the youngest guardian present by far and definitely the most stared at by everyone around.

He hoped the middle school had enough facilities to hold everyone comfortably.

’Right... I unlocked my Bloodline Skill last night,’ he thought as a heavyset older brother was called into the classroom ahead of them.

Nami was leaning against his side, her head resting comfortably on his shoulder. Although he felt the urge to flick her forehead as a tease, he let her stay.

She’d been taking excellent care of Reona while juggling her KCAC work and dealing with all the chaos of his life... She deserved this moment of peace and much more so he would give it to her.

’Maybe I should buy her something,’ he considered. ’Or rather, buy all the girls proper gifts. I’d have to go overboard with Hakai’s card anyway. Might as well make it meaningful.’

He focused inward. ’Now let’s check the Bloodline Skill... Skill Tree.’

The color seemed to drain from the world around him as his Skill Tree materialized in his vision. It branched into several complex paths... it was more boisterous and elaborate than the last time he’d checked, probably because he’d been leveling up skills consistently.

But there was something distinctly weird about his Skill Tree now.

Namely, a crimson eye that seemed to be looking directly at him. It was like a jewel embedded at the center of the tree. It felt like he could get lost staring into it.

「Bloodline: Sovereign Vessel」

「Purity: 92%」

「Description: ???」

’System... what’s this Sovereign Vessel Bloodline?’ He thought, pressing for more information. ’What does it mean?’

「Unable to answer due to insufficient information about the world’s history and bloodline origins... Data is restricted.」

’As expected...’ He thought with mild frustration. He wanted to know more. Was his body some kind of vessel for something? What did "Sovereign" even mean in this context? ’I’ll try to research this later when I have time. But can you tell me why I went that hard on Hakai last night? It genuinely looked like I was about to kill her or something.’

She wouldn’t have died... she was far too strong for that but still, his behavior had been extremely aggressive. He could remember everything and he remembered being in control but that was unlike him.

「Host’s Bloodline was actively awakening during intercourse. The excess energy generated from that awakening process had to be vented physically. It will not happen again unless Host’s Bloodline Purity increases significantly though once inside a woman, you will feel the need to take her.」

’Okay, good to know.’ He thought with a mental sigh of relief... at least it wasn’t a permanent personality change.

Now he opened his Bloodline Skill tab properly.

「Bloodline Skill: Genetic Inheritance (S)」

「Function: Absorb and utilize genetic information from intimate partners through mana resonance achieved during sexual intercourse. Collected genetics can be equipped into limited slots for temporary use.」

「Current Level: 1」

「Registered Partners: 1」

「- Amagi Hakai ( Darkness Affinity)」

「Available Slots:」

「→ Affinity Slot: 1」

「→ Skill Slot: 1」

「→ Trait Slot: 0 [LOCKED]」

「Restrictions:」

「- Equipped abilities lock for 24 hours after activation」

「- Inherited abilities cost 1.5x normal mana (affinities) or 2x normal mana (skills)」

「- Proficiency starts at 0% and must be trained」

「- Maximum partners that can be registered: No limit」

「- Swap limit: Once per 24 hours (early level)」

’Huh...’ His throat went dry as he processed the information. It absorbed genetic information from women he slept with and let him use their abilities temporarily? What the hell kind of bloodline was this?

He mentally tapped on the Affinity Slot option.

「Equip Affinity:」

「Darkness (Belonging to Amagi Hakai) can be equipped.」

He tapped mentally to confirm.

Immediately, he felt his body change. Unlike the other elemental affinities he’d tried to learn before, which never took effect properly, this one worked instantly.

His shadow on the floor began flickering strangely, rippling like disturbed water, until it suddenly stopped and stabilized.

’It actually worked?’ He tested his control carefully, focusing on a shadow cast by the overhead hallway lights a few feet away.

The darkness actually moved the way he wanted it to, responding to his mental commands like it was an extension of his body. ’This is incredible...’

He went to the Skill Slot next and several options populated:

「Analytical Sight (C) can be equipped」

「Shadow Step (B) can be equipped」

「Void Threads (A) can be equipped」

「Darkness Manifestation (A) can be equipped」

「The rest of the skills wielded by Amagi Hakai cannot be equipped at this stage」

He mentally tapped on Darkness Manifestation and confirmed the selection. He wanted to test it out immediately, but... 𝗳𝐫𝚎𝗲𝚠𝚎𝗯𝕟𝐨𝘃𝚎𝗹.𝗰𝗼𝗺

There was a tap on his shoulder that pulled him from his thoughts.

"Huh?" He dismissed the Skill Tree interface and looked at Nami, who was now standing.

"Guardians IAD32, please come in," a voice called from inside the classroom.

That was their number. Koya stood up. He and Nami walked to the classroom door together, pushed it open, and entered.

The classroom was full of students... about thirty fifteen-year-olds seated at neat desks arranged in rows and their eyes all turned to look at the newcomers with curiosity.

Koya smiled slightly at the sea of young faces.

The teacher... Ms. Fujimoto, according to the nameplate on her desk stood at the front with a welcoming expression. "Please introduce yourselves to the class."

Koya nodded and looked at the students properly.

"I’m Amagi Koya," he said clearly. "I’m Reona’s older brother and legal guardian and this is Nami... she’s a fellow Guardian as well, one could say we are together."

He just didn’t want to have to explain complex stuff... it was better for them to assume that they were dating or something. He failed to notice Nami’s red face afterward.

For a moment, there was complete silence in the classroom.

Then someone in the back row stood up abruptly. "WAIT. You’re THE Amagi Koya?! The four-liner who killed four Iron class monsters in minutes?!"

The entire classroom ERUPTED with noise.

’I guess it’s good to be famous...?’
