Plans+Vampire 3 - (Rosario+Vampire Capu2, OC!I)

Out of the current members of Tsukune's Harem, Kokoa is without a doubt the worse at this point.

In a more general sense, she would pale before the others, but her current behavior and lack of interest to abide by the rules meant that she was a threat to anyone she found worthy to nag, annoy, and even try to kill. Early on, that was solely aimed at her sister since she wanted her 'real oneesan' to pay her attention and play with her.

She was a brat, through and through, so-

"You're a human."

The affirmation caught me barely off-guard. First, I was paranoid as shit, so I was expecting some sort of mess like this to happen and I had been prepared for it. Second, I doubted she had proof of this, or she would have not come here to bother me on her own.

Tsundere or not, Kokoa wouldn't miss a chance to get her sister on the case if it meant spending more time with her and, since she was there alone, I could tell the redhead was not able to outright prove it.

"I am not."

And third, it was just me and her in my little workshop by one of the sheds given to the Alchemy Club for those working metals to create jewels or weapons to be sold or 'kept'. In my case, I was trying to use the last few lessons on metallurgy and blacksmithing I got from the club to create something 'better' to defend myself with.

I couldn't get myself anything too big or too deadly, so I decided to create a dagger. It would have a few protective runes meant to give me extra resistance at the expense of the weapon's endurance. The process required at least a month to see the blade forged and a week to get all the proper runes done so... nothing I could use against Kokoa, but a work-in-progress project that would be useful in the long-run.

"Your blood is human."

So it was about yesterday's cut. I had thought that the two vampiric siblings had not caught up to that, but I guess Kokoa was less geared for Tsukune's blood and looking for other supplies of the red juice. Still, nothing that I was truly worried about.

"...And?"

My lacking answer irked her quite a lot. "A-And that means you're a human!"

"Do you know that monster blood has the capacity to carry a smell that are similar to others? Like, have you tested the smell of the blood between a Cockatrice and a Harpy? I bet they smell the same to a vampire."

Kokoa appeared annoyed but also confused. "Do they?"

"You're the vampire, Shuzen-san," I argued, finally giving her a glance. "So?"

...

"I-I guess. But that doesn't mean that you are not a human."

"Why?"

"What's your species then?"

"Secret. But I am sure your little club can dig into my school files as safely as possible without getting 'caught' by the principal'."

"...What?"

I shrugged. "Just ask your big sis. Look, I am a busy guy and I don't care enough to be bothered for long so-"

"If I beat you in a fight, you will tell me."

And here's the main challenge. Kokoa's mind is hardwired in getting into fights. She is a fight-junkie of the tsundere bratty kind. The more you try to be too much or too little dominant around her, the higher the chances of incurring in that habit of hers.

"I don't think that's how it will go."

"Too bad that you don't have a choice," She smugly remarked, Kou-chan already morphing in a large mallet. "So, let's fight!"

Ah yes, predicting this sort of situations was something that nagged at me the first week of school. I really sweated bullets being caught before I had something already staged to deal with each and every single member of that harem.

After all, I was the one with the two factors needed to beat such a cast of foes in the eventuality of getting targeted for bullshit reasons: I had awareness of their flaws and I had time to get something cooked to face each of those individually.

I have yet to find a way to face them all at once, but I was confident they wouldn't have come all at once at me if I kept in the background. And this was proof of that. Kokoa was actually the hardest to predict due to Kou-chan being such a versatile tool to break and smack through obstacles, while Kokoa was outright a speedster in terms of bare-handed combat.

Both details were extremely diluted by the fact that she was a 'proud vampire', a cocky brat, rather insecure about herself, and, most important of it all, quite narrow-minded in combat when provoked just enough. Dodging the first strike was the biggest moment. She either 'played' with the food, or she went all out.

In my case, she was a bit of both but leaned more on the former. Kokoa's mallet merely 'pushed' me with the pressure its swing caused as it missed me by a few moments. The redhead was expecting me to be some sort of 'weak human', so she was ready to hold back to prove a point.

A point I was going to make her regret trying to make because it jeopardized my survival at school. Stamina was the next important step in this 'fight', as I had been taking a hour-long run around the dorms early in the morning right behind classes. It gave me the chance to build muscles for my legs, while also giving me greater cardio to face sprints as intense as this one.

Kokoa still had me beat on physical stats and even as she paced through and barely kept behind me, she could have easily caught up to me and gave me hell but she was playful through the chase. I was insignificant to her, clearly 'frightened' to face her straight up.

"Coward! I will smack your face in!"

Ironic that she calls me, the cunning bastard that I was, a coward when her father was known to dodge direct confrontations when possible. In fact, I never understood the pride thingy that both Moka and Kokoa had. Maybe it was before the mangaka had the chance to flesh out Issa, but it sure felt quite shocking that they both could have that sort of habit to 'face things fairly' when their father was a fucking hitman.

Nonetheless, I didn't return the insults. Merely leading her around until I found my way to the hallways I was looking for. Quite far from where most students would lurk, especially at this hour, this abandoned area of the school was hardly used and thus could be employed to set up a trap.

As I passed through the hallway, I placed down a small gem I had with me, the gem glowing together with two of those I had previously left there for the trap, runes activating as the natural energy within them was activated.

I may have no magic, but runic gem could also use natural energy that was always present in the air. The gems then sank on the floor, seemingly vanishing right as Kokoa was passing through and, timing my other gem, I saw her suddenly trip and then remain stuck on the ground. Kou-chan went flying but was caught up by the gem I had held in my hand, sealing him for a full hour.

Kokoa struggled against the muddy and slimey floor, her super-strength failing to get her out of that.

"W-What is this?"

"A runic spell known as 'Slime Floor'. Its purpose is to limit mobility to any victim to it for the duration of a hour. A little trap I prepared in case I was to face a moron of your caliber."

Growling, the redhead tried to push even more to free herself but... nothing. Physical strength was worthless when someone as small and limited as Kokoa was stuck in that situation, and while her arms and legs were caught by the slime floor, the rest of the body was actually free.

"What do you think of- of doing with me?"

"I will tell you what I am not doing, which is sexually assault you. First, it's a horrible practice some monsters have, and, second, you are not exactly my type as a partner. The lack of consent doesn't improve that you are a brat," I answered readily and I moved around her, circling her like a shark. "And since you are a brat, you deserve correction that your beloved sister was unable to grant you."

"W-What?"

"If you are to break a vase in your home, what would be the punishment?"

"...Spanking?"

I grinned. "And if you were to annoy your big sister, what was the punishment she would inflict you?"

"Sp-Spanking."

"And what do you think you are getting out of this experience because you behaved around a brat with the wrong person, Kokoa-tan?"

"...N-Not spanking?"

"I am afraid that your fate has been decided. Twenty slaps on your nude bum should do."

"T-That's not happening!" She screamed, but she couldn't prevent her skirt and panties to be lowered just enough to reveal her pale buns. "S-Stop! This is not right! This is unfair!"

"Unfair, you say? Then maybe I should up that to 25 for the cheek!"

Since threats were failing, she tried to beg but- Kokoa's efforts were cut short as I started to spank that butt red. Twenty five slaps for a spanking session may sound bad for a privileged kid, but Kokoa was blessed by having a doting step-mother and an equally ruthless step-sister that gave her what she needed- a good ol' spanking to get her to mature up.

Sadly, it wasn't too frequently and extensively, but I knew how to spank a brat and I showed her this much by giving her a proper trip down those memories of punishment. Kokoa was crying and bawling for 'daddy' to stop spanking. Which was hilarious since I triggered some memories of Issa doing this, and also disgusting as it could be seen also a kink shit thing so... I didn't do much more after leaving her bum burning red.

Kokoa was depleted by the spanking, her skirt and panties lifted back up as I made sure no one would bother her for the remaining twenty minutes before the runes would run out of natural energy. Still, I decided to give her a warning.

"Next time, Kokoa-tan, it will be fifty and I will bring a paddle. Threaten me again, annoy me once more, and I will show you that brats like you will never win against someone with maturity and common sense."

"...I hate you."

I shrugged at that and went to leave. Some may question this decision- this 'punishment' so to speak, but it was all centered around Kokoa's personality. As a brat, being punished as one with the kind of punishment she was quite familiar with would bring up the memories of why trying to be a brat again is wrong around a specific individual.

Considering she was hardly into this sort of shit by canon's standards, I was quite confident that would be the case and... it was indeed the case.

The next day, Kokoa would not be stalking my steps, and the only time we crossed paths, she would rush away the moment she noticed I was there. I had been also worried that her sister may spot this too, but Kokoa was also a 'proud vampire' and she would never tell her big sis she got tricked by a 'human' and then spanked into submission by him.

Oh no, the humiliation would be the worst thing possible.

And as peace returned in the horizon, the plot of Capu2 would proceed as the harem was not the only threat to my survival.

The best way to deal with a brat is to correct 'em with spanking!
