I Don’t Want to Die as a Mob in My Second Life! ～A Story Where I Kept Training from Inside the Womb and Ended Up Being Mistaken for a Monster～ - Chapter 18: Kanata's Speedrun to Conquer the Kirisame Family

Chapter 18: Kanata’s Speedrun to Conquer the Kirisame Family

“Stolen, stolen, stolen, stolen! How dare he, how dare he, how dare he, how dare he…!”

The cool, sideboob-sporting older sister of the Kirisame family, Setsuna Kirisame.

At just eighteen years old, she’s already a top-tier Reisoushi with exceptional talent.

A favorite of Ouma Shiranui and a future big name in the Spirit Conductor Agency.

“My sweet little Sharo has been twisted by this guy…!”

In my unremarkable past life, she was an untouchable elite of the spirit world.

Now, though, she’s convinced I’ve “stolen” her sister Sharo and is absolutely losing it.

Muttering to herself with lifeless eyes, she stared at me like I was the scum of the earth.

Uh… creepy.

“Big sister Setsuna! Kanata hasn’t done anything wrong! It’s all my fault!”

“Ohh, is that so? Is that so? Sharo, why don’t you step aside for just a moment…?”

Sharo tried her best to defend me, but Setsuna clearly wasn’t listening.

Also, Sharo, please stop. That line is literally the number one thing someone brainwashed by an abusive boyfriend would say.

“…Kanata Soranaki. I’ll admit my sister Sharo doesn’t have the most admirable personality.”

Uh… okay?

“She won’t eat vegetables, hoards all the snacks for herself, and insists on being the first to use the bath even though she’s the youngest.”

“Uh, Miss Setsuna Kirisame?”

“She knows she’s cute and used that to form a reverse harem in kindergarten. Oh, and she used to get scolded a lot for sticking branches into the family dog Kenta’s rear.”

“Um.”

“But! For her to get caught up with an evil monster like you, no matter how good-looking, is beyond cruel!!”

“Would you listen for a second?”

I didn’t “catch” her, okay? And where did the cool and composed character go!?

“…A Muramasa-made kunai… shattered, huh?”

Setsuna glanced at the scattered shards of the blade on the ground—the one I broke.

“Kanata Soranaki. I may not know the exact circumstances, but the fact remains—you involved my sister. You pushed her into a corner, broke her spirit, and then used kindness to manipulate her. That’s textbook brainwashing!”

That’s technically accurate but completely wrong in context!

“My adorable Sharo…! Sure, she’s cheeky, but that only makes her even cuter as a sister…!”

Setsuna plunged her hand into her loose kimono, pulling out a slew of ofuda (charm tags).

Next to her, a woman in white ceremonial robes exuding icy cold appeared—her Spirit, [Snow Woman].

Okay, okay, hold on a second!

“Miss Setsuna… you’re not seriously—”

Is she actually planning to fight me!?

“Setsuna Kirisame, top-tier Reisoushi. For the sake of love, I’ll execute you!”

With that, Setsuna scattered her charm tags and rapidly formed multiple hand seals.

Then—

“Charm Crafting Canopy—Bloom in Glory, [Frozen Death Petal Garden]!”

The very space around us shifted.

The sky turned into a desolate, icy wasteland. A castle and a frozen garden materialized, encasing me within the frigid domain Setsuna had created.

It’s freezing. My breath didn’t just turn white—it turned into icy particles. Fierce snowstorms slammed against me relentlessly.

This…

“Charm Crafting Canopy… A technique that allows advanced Charm Crafting users of rank A or higher to imbue an entire space with spiritual power.”

“Yes, you’re well-informed.”

If Object Imbuing’s pinnacle is Object Imbuing Manifestation, this must be the ultimate form of Charm Crafting.

Squinting, I could see charm tags forming a dome-like structure around me.

Beyond the barrier, Sharo was pounding against the frozen wall and shouting, “Big Sister, don’t interfere with love! You don’t understand the bond we share!“

Stop saying things that sound like something someone brainwashed by an abusive boyfriend would say.

Meanwhile, Dad was frantically on the phone somewhere. Honestly, he’s the only one keeping things sane right now.

“Hmm… (That castle behind Setsuna. On closer inspection, it’s embedded with countless charm tags. That must be the core.)”

The charm tags shaping this world and the symbolic structure representing its power…

These act as the foundation for creating this unique barrier. For now, the entire space itself has become my enemy.

“This Canopy is my world. And it will be your final resting place. Here, I can do things like this…!”

She sharply pointed her fingers at me, and immediately, ice shackles bound my arms and legs.

And then—

“Come forth, frozen warriors!”

Hundreds of ice-sculpted samurai materialized around Setsuna.

The castle of ice, the samurai warriors—all surrounding Setsuna made her appear almost like,

“A princess in her castle.”

“Are you trying to seduce me too!?”

What!? No! Where is she getting these ideas about me!?

“You vile charmer. I’ll put an end to your mischief before you can corrupt anyone else! Attack, warriors!”

――!

Without a word, the armored samurai army charged at me, wielding icy blades.

“I see…”

In my previous life, this would’ve been a hopeless situation.

Bound by ice, surrounded by hundreds of armed enemies—there’s no way I could have survived.

But now—

“You’re too soft.”

“What!?”

Without so much as breaking a sweat, I broke free from the icy restraints.

No techniques, no spells—just the raw power of the body I developed in the womb.

And then,

“Trace: Hakkyokuken—!“

Mimicking the movements of a master, my body kicked into gear.

First, Shaking Stomp. A step so powerful it made the ground tremble. The force surged into my knees, storing explosive energy.

In an instant, I closed the distance to one of the ice samurai with the speed of a lightning strike, driving my elbow forward in a precise Exploding Elbow. The blow shattered the samurai’s chest plate and sent it flying backward, knocking down the soldiers behind it like bowling pins.

Another samurai swung its blade from my right. I countered with a swift Double Collision Palm, catching the attack between both hands and striking back with a powerful palm thrust.

The impact sent more of the samurai flying. Without missing a beat, I pivoted my body, sweeping the legs out from under a nearby samurai on my left, momentarily lifting it off the ground.

“Hakkyokuken, Eight Ultimate Techniques: Piercing Cannon!”

With its defenses wide open, I landed a devastating two-fold strike—a palm thrust followed by a fist blow—to its torso.

All of this unfolded at near supersonic speed, leaving the ice samurai army in complete disarray.

“What—what is this…!? Such strength…!?”

“Thank you, Miss Setsuna.”

“What!?”

I figured I’d thank her in advance.

“I was planning to start practicing Charm Crafting next, so this is turning out to be excellent training.”

It wasn’t meant as mockery; I genuinely meant it.

For this body of mine, even a battlefield like this was the perfect training ground.

“Go ahead, summon more of your samurai. I’ll take them on with Charm Crafting this time.”

“You… you…!”

Setsuna’s face turned bright red, and even the side of her chest gained a faint blush.

“Heh?”

I raised an eyebrow, genuinely surprised.

In the future, she was always expressionless, her gaze perpetually cold. Many called her the “Ice Queen,” especially since she remained unmarried.

But now, here she was, showing such raw emotion.

“…You truly love Sharo, don’t you?”

In this second life, I understood why she became like that.

Sharo’s death at the hands of the Conceptual Spirit [Erasure]. The stain it left on the Kirisame family.

And despite Sharo’s foolishness, Setsuna loved her deeply—so much so that it consumed her.

“You have such an expressive face, big sister.”

“—!? Don’t you dare call me that!”

Oops, seems I struck a nerve.

Her rising anger summoned even more ice warriors, who charged at me with renewed intensity.

As they closed in, I reached into my pocket and pulled out some charm tags. Alright, time to get serious.

“Charm Crafting, unleash—[Blank Shot]!“

――!

I imbued dozens of charm tags with [Blank Shot], scattering them in the air. They exploded like bombs, sending shockwaves that shattered dozens of ice samurai.

And then,

“Let’s try something new. Charm Crafting, command—[Doll].“

I infused one of the charm tags with [Doll] and casually slapped it onto a random ice samurai.

In an instant, the ice samurai froze in place. Its icy form began to melt and reshape itself into a graceful sword maiden.

Clearly, this was [Doll]’s aesthetic at work.

“Character design updated! Let’s go!“

Satisfied with its new form, the sword maiden—now under [Doll]’s control—let out a spirited cry and began slicing through the surrounding samurai.

Its stats were comparable to the other ice warriors, but its technique was leagues apart. Unlike the clumsy movements of the others, the [Doll]-possessed warrior fought with brilliant swordsmanship, cutting through enemies with ease.

That move… it’s using “Trace: Yagyu Shinkage-ryu.”

As the ice warriors fell to one of their own, Setsuna stood there, speechless.

“My… my ice warriors are…!?”

“I’ve taken control of them. The concept of [Doll] includes ‘manipulation.’ I’m glad the attempt worked.”

Hijacking someone else’s summoned minions? That’s typically categorized under Curse Wielding and considered an advanced technique.

Of course, every swing from the sword maiden was draining my spiritual energy at an alarming rate, but I decided not to let it bother me.

This second-life version of me is a monster, after all.

I’m not about to get cocky, but I also don’t need to fight with the stingy, small-scale tactics I used in my past life.

Resources are meant to be spent boldly when necessary. This fight with your sister taught me that.

“Charm Crafting, activate—dance, [Ittan-momen].“

I infused several more charm tags with [Ittan-momen] and scattered them around me.

As they activated, they formed a mandala-like pattern in front of me, triggering a bizarre phenomenon. The icy blizzard that had been pelting me suddenly shifted its vector—redirecting straight toward Setsuna.

“Ugh…!”

Setsuna raised her arms to shield herself, but the relentless barrage of snow slammed into her. Her body was quickly coated in white as the frigid world she had created began turning against her.

“This… this is my own ‘Canopy’! How… why!?”

“You let your guard down. Charm Crafting Canopy is a technique that creates a controlled environment. But an environment, once altered, can just as easily turn against its creator.”

“Altered environment… wait, you don’t mean!?”

Looks like she figured it out.

“[Ittan-momen] represents the concept of self-propelling objects. Once anything moving comes into contact with a charm imbued with its power, that object falls under [Ittan-momen]’s control.”

By using this, I took control of the blizzard itself, redirecting the storm to assault Setsuna.

“Should I go ahead and strangle her tight?“

“No, [Ittan-momen], stand down.”

If you strangle Setsuna, parts of her are going to turn into a boneless ham, and we really don’t want that.

“Y-You really are… a monster…”

At some point, Setsuna Kirisame had dropped to her knees.

Her body was trembling, her exposed skin pale blue. She was clearly succumbing to hypothermia.

“From the moment you were in the womb, I feared you…!”

Setsuna’s voice trembled as she spoke. 

“A soul hosting multiple Conceptual Spirits, your spiritual power multiplying endlessly every day, and your body undergoing such unnatural transformations…”

Well, yeah. I get it. That fear isn’t misplaced.

I admit, I’ve gone a little overboard myself.

“As a member of the ‘Kirisame family,’ who has protected Japan since long before Ouma Shiranui’s reign, I couldn’t turn a blind eye. If you ever showed signs of becoming a tyrant, I was prepared to kill you. It’s my duty as the next head of the Kirisame family!”

That’s admirable. Truly. But,

“Looks like you couldn’t fulfill that duty, could you?”

“Ugh…!”

Setsuna finally collapsed, sprawled out on the frozen ground.

She managed to raise her face to glare at me, but her strength was clearly spent. Her army of ice soldiers had been completely wiped out as well.

“Thank you, Miss Setsuna. This turned out to be a fantastic lesson in Charm Crafting.”

I gave her another polite nod before raising my hand and forming a sword-like gesture with my fingers.

It was time to call it a day.

“Gather under me, my spirits,” I commanded softly.

Now to finish this.

“Spirit Hosting, activate. Reside within me, [Doll]. Object Imbuing multiple layers—resonate, [Ittan-momen], [Blank Shot].”

I hosted [Doll] within myself, summoning threads that extended outward.

By imbuing those threads with [Ittan-momen], they moved autonomously, picking up the scattered blades of the ice soldiers.

Next, I infused the threads with [Blank Shot], activating it repeatedly. The threads vibrated intensely, turning every sword they carried into a deadly oscillating blade.

Seeing this, Setsuna’s expression twisted—a mix of terror and grim determination.

“Such a monstrous technique…! Fine then… just kill me already!”

“I won’t kill you.”

Honestly, this whole “evil monster” label is getting tiresome.

“Lies! A creature like you couldn’t possibly possess mercy!”

Sigh…

“—You need to shut up, pig.”

“Wha—!?!?”

Ah, crap. That slipped out harsher than I intended.

Oh boy. When I get annoyed, the polite filter really just vanishes, huh? Setsuna was left trembling in stunned silence. My bad.

“P-Pig…? A pig!? No one has ever… ever called me something so cruel…!”

Yeah, I get it. Being rich and gorgeous, she probably never heard an insult in her life. My bad again.

To make up for it, I forced the kindest smile I could muster and said,

“Alright then, dear older sister. Please get along with your lovely little sister, okay?”

With that, I launched the vibrating blades.

They shot past her, shattering the icy castle at her back, and dismantling the frozen world she had created.

[Tips]

[Snow Woman]:

The spirit bound to Setsuna Kirisame. A legendary Conceptual Spirit shaped from folklore.

Her concept stems from “living with a man in endless snow,” making her a perfect match for techniques like Charm Crafting Canopy.

Though she rarely speaks, she is surprisingly kind-hearted, as seen in the folktales where she lived with her husband until her true nature as a yokai was discovered.

She often creates icy objects for Sharo at her request. However, when Sharo tried to shove one of those ice sticks into the family dog’s rear, [Snow Woman] lost her temper—completely.

Even her usual silence couldn’t stop her from shouting, “SHARO YOU LITTLE BRAT!”

Sideboob:

A signature feature of Setsuna Kirisame’s peculiar fashion.

She wears a unique kimono that prominently showcases her voluminous sideboob.

This is not because she’s some depraved woman (or, as Kanata might call her, a “perverted pig”). It’s to harmonize with her bound spirit, [Snow Woman], by lowering her body temperature.

Everything she does—including the revealing attire—is for the sake of her position as the next head of the Kirisame Family.

She’s serious about flaunting her sideboob.

Boneless Ham:

A reference to a hypothetical ending for Setsuna Kirisame. Incidentally, Kanata’s favorite food is pork.

[Charm Crafting Canopy]:

The pinnacle of Charm Crafting.

Using charms imbued with spiritual energy, a dome is created to construct a unique space—referred to as the “canopy” (not to be confused with a pork dish).

This technique relies on a combination of charms that shape the space and a large symbol that serves as its core.

[Frozen Death Petal Garden]:

Setsuna Kirisame’s Canopy, creating a frozen garden.

The space is filled with freezing energy, capable of freezing any targeted area.

It also allows the creation of moving ice statues and can sap an opponent’s body heat.

While it is a powerful Canopy, Setsuna herself avoids the cold by using the castle at its core to emit a constant blizzard from above, ensuring only her opponent suffers from the freezing effects.

To counter this, one must either reach the base of the castle or use a technique to redirect the blizzard’s path.

Similar to Maro’s Imbuing Manifestation [Dagon whip], the ability itself is incredibly strong, but…

Kanata’s Best Attempt at a Smile:
No matter how much he tries to look friendly, the dark aura still leaks through.

 Pig:

Setsuna.
