Our Daughter is Such a Filial Child~

Yes, it was a fight that couldn’t have been possible from the start.

The opponent is the strongest being created with great care by the developers.

A mere war veteran like me is no match for such an opponent.

“Amazing, our daughter.”

How long had I been immersed in that helplessness?

The moment my body, drained of energy from the shock, sprawled on the ground, she closed the distance and began to point the tip of her sword at me.

“If the gap had been just a little narrower, you might have reached mom… If you had held a weapon, would the result have been different?”

Swish.

The sword handle is presented as the blade turns.

As soon as I faced it, my hand roughly swung to push away the handle.

“…Get that away, it’s been over 12 years since I’ve held a sword.”

And damn it, if you’re going to give me a proper one, why specifically a Japanese sword?

How is giving such an outdated weapon any different from blatantly telling me to eat shit?

“Oh my, that won’t do. As mom has told you many times, you should consistently practice swordsmanship… Hm?”

That damn woman expressing regret as if displeased by my action.

But even that muttering ceased suddenly as she stared at my chest.

As if she recognized what the red cross necklace around my neck was.

“Ah, I understand now.”

A faint smile gradually appears on her lips.

Along with that, her head slowly begins to bow towards me.

“Our Seine, you’ve given up on defeating mom while I wasn’t looking, haven’t you?”

“……”

“…Am I right?”

No, from the start, I was full of thoughts of killing her when I met her.

I just closed my mouth for a moment, realizing why she said such a thing.

“Wearing that necklace means you’ve essentially given up on fighting as a profession. Don’t you think it’s too greedy to try to defeat mom in a head-on battle now?”

“…Shut up.”

Isn’t that something you should say after dropping my head to the ground?

I stood up and checked my body’s condition while maintaining distance.

Not a single place is broken, nor is there any bleeding.

Because she didn’t land a single effective hit on me.

“Don’t tell me you’re planning to continue?”

But when I heard her subsequent voice, I could no longer think of charging at her madly like before.

Because I felt the overheated fervor gradually cooling down.

“…Well, I should acknowledge what needs to be acknowledged.”

Eventually giving up on charging at her, I quietly raised both hands above my head, conveying a certain intention.

The intention not to continue the fight any further.

“That this is the limit of what I can do now.”

Although I didn’t know the process, the result was indeed no different from 12 years ago.

I can’t defeat her. Whether in a head-on battle or by ambush, it would be the same no matter what method I used.

“Yes, I’m glad you understand. Then let’s end the fight here and have an emotional reunion… Huh?”

But you know what?

Even if it’s impossible for me to kill this person, there’s still a way to make her eat shit, isn’t there?

“Wh-What!? When did you…!!”

Belatedly noticing what was grasped in my hand, she hurriedly looks down at her chest.

There was really nothing there.

Her clothes were torn, and even the bandages wrapped underneath were torn, revealing only an empty chest.

Although there was something that could be called a curve before, now that the contents have been removed, it’s as flat as a sports field.

“When, you ask? It’s because you wear such things that you can’t even tell whether a hand touched your body or not, you bitch.”

I brandished the prosthetic I held in my hand, showing it off to her.

Soft and elastic… Wow. It’s clearly felt that this was made with thorough preparation.

Did she covet what she couldn’t have herself?

“By the way, isn’t it embarrassing to wear padding at that age? Were you that upset about being small?”

“Y-You, what are you saying…!”

Seeing her flustered, it seems I hit the mark perfectly.

Of course, just looking at her current appearance, it’s all visible how she’s done all sorts of crazy things to look young.

How could she maintain her composure when her shame is exposed after growing her chest out of greed on top of that?

“You shouldn’t play with mom’s things, Seine! Quickly, won’t you return that to mom!?”

“Fuck off.”

The moment her foot moved, a spark erupted from my hand with a fizz!

The current, which flared up excessively while receiving even the surrounding rainwater, instantly burned the prosthetic.

“Kyaaaaaah!!”

She screams, unable to prevent it in the end.

Her small body collapses onto the ground where ashes are scattering, but I couldn’t feel completely satisfied seeing such a miserable sight.

Damn, the strongest in the world setting falls like that just because some padding was burned?

There should be a limit to stuffing in characteristics that don’t match. Damn developers.

“…That’s too much.”

Unaware of my inner thoughts, the damn woman sits in the muddy water, pouring out her grievances.

“Seine, that’s too much!! How could you do such a cruel thing to mom? What on earth happened while I was away… for our angelic Seine to grow into such a bad child!!”

“Did this woman not only get dementia but also undergo a frontal lobe lobotomy?”

Angel? Which part of me is she looking at to say such a thing?

I’ve replaced practice swords with real ones during duels, visited her bedroom with a knife, mixed laxatives and acidic substances that would burn the esophagus into food meant for the dining table, and even sawed the wheels of the carriage she rode.

And this woman has not only erased all of that from her memory but even distorted it to her liking…

Or is she perhaps not referring to the fairy tale-like angels made of feathers and light, but the angels from the original texts?

Like those Cthulhu-rivaling beings with bodies covered in eyes and feathers protruding like tentacles?

“Teacher Seine.”

…No, now is not the time for such pointless evaluations.

Turning my gaze away from the damn woman crying pitifully, I glanced back at the person who had followed behind.

In the middle of the forest, quite far from the infirmary, Saint-nim was facing me with just an umbrella to block the rain.

She was panting, and her shoes were soaked.

“A-Are you alright?”

Nevertheless, in her eyes, I could feel concern directed towards me.

“I’m fine, so you don’t need to worry.”

“Yes, that’s a relief, but…”

After that, her gaze, which had felt relief, gradually shifted from me to the side.

Towards the old hag still lying face down on the ground, acting like the heroine of a tragedy.

“Um, from what I’ve heard, that person is Seine-san’s moth…”

“She’s not my mother.”

It was the truth.

“She’s just a mentally ill person who thinks she’s my mother.”

It was also the truth.

If necessary, I could even bet a token of trust on it.

By touching my thumb and pinky to my tongue and forehead…

“…It seems your family situation is quite complicated.”

But Saint-nim restrained my action as if understanding that as well.

Although I had been harmed by that woman, what she showed in front of me was not resentment, but only concern for me.

The moment my fiery temper that had been raging until now subsided.

“…Sepin-san, I think it would be good for you to head back soon.”

But that too would be only for a moment.

Turning my back on her, I quietly looked back at the person collapsed on the ground.

“Pardon? But…”

“I don’t want to show any more unsightly appearances.”

Yes, the hatred towards that person is solely mine.

As it’s a calling that I alone must cherish and fulfill, I had no intention of forcing it upon anyone else.

“…I see, then until next time.”

Saint-nim retreats, even keeping her farewell brief.

Leaving behind her, whom I would meet again in a few days, I began to close the distance with the person still lying on the ground.

“Come along quietly. Don’t think about harming others.”

There are other important matters at hand, after all.

---

After sending Saint-nim away, I returned to the infirmary with the damn woman in tow.

Upon returning, I found that rain and wind had greatly infiltrated the infirmary through the broken window.

It seemed it would take time to clean up as it was quite messy, but for now, I decided to block it roughly as a temporary measure and clean up later.

Now was the time to contemplate how to kill the person I had brought along.

“Hehe.”

But why is this crazy woman suddenly giggling?

“What’s so good that you’re giggling like that?”

“Hm? Well, I’m happy because I discovered where Seine works.”

The damn woman sits in the provided seat, smiling stupidly.

Even her usually dull-looking eyes are sparkling brightly at this moment as she looks around.

Who would think that this woman is an old hag who’s lived for half a century?

“To think that the child who was so young has now grown up to properly become a teacher, and moreover, is doing work that saves people… Mommy is happy that Seine has grown into a mature adult, you know?”

The maturity you speak of is something I can never have because of the genes you passed down.

Tsk, I clicked my tongue and poured water from the boiling kettle into the cup in my hand.

Hot water with steam rising. Setting that aside for a moment, I reached for the most secluded place in the medicine cabinet.

To unlock the device stored securely behind it, and to take out the object stored inside.

“Drink.”

When I casually handed it to her after adding a drop of its contents, her eyes widened.

“Seine. Are you making tea for mommy?”

“Yes, I made it personally, so shut up and drink.”

“Oh my, to think that Seine would care for mommy like this~! Mommy is touched!”

“Enough, just drink it.”

“Of course! I should drink as much as I can of what Seine made for me.”

Hehe, the damn woman laughs as she brings the tea I made to her lips.

I didn’t take my eyes off that sight and gripped the medicine bottle in my pocket.

The pharmacology I chose as a minor following my major in surgery.

Expecting and longing for the worst poison created using that knowledge to enter her mouth.

“Cough!”

Yes, even she won’t be able to withstand this.

The poison I used now has a fatality rate that far surpasses not only cyanide but even tetrodotoxin extracted from pufferfish.

Scientific name – Botulinum toxin.

The botulinum bacterium, which exists commonly everywhere, mainly causes food poisoning, but the substance refined from it is among the most powerful poisons discovered by mankind.

The lethal dose is 10 nanograms, incomparable to the 300 micrograms of tetrodotoxin.

Theoretically, with just 400g, it’s possible to create a biochemical weapon that could annihilate billions of people.

Of course, it’s very difficult to make because it needs to be refined from the bacterial level, but once made, it’s something that can easily send a person to their grave.

“Ugh, uwa, cough…!!”

Yes, no matter how strong she is, it would be impossible to withstand this poison.

Just by engraving in my eyes the sight of her clutching her throat in agony, I could feel that the wish I had longed for so much had been realized.

“…Aha~♥”

For about 27 seconds only.

“I feel like I’ve gotten about 10 years younger. My skin has become so soft… Ah, could it be thanks to the tea our daughter gave me? Oh my, giving mommy a medicinal decoction for skin beauty as a gift~ Our daughter is such a filial child~”

“You damn bitch.”

This woman is doing Botox with what I gave her to die.

Even though poison can be used as medicine, having an ‘All Poisons Immunity’ constant passive is too much, you damn developers.
