I stop in front of the staircase leading to the 100th floor.

「Finally, this is it」

「Looks like it」

「…… That, I'm sorry. My tension went up uncharacteristically……」

「It's alright. Such Tira was also cute」

「…… Mou, stop it already, please. Stop teasing me like that」

I'm only saying the truth, though.

「Now then, whether you like it or not, this is the top floor. Let's go」

「Ah. Before that put me down please」

「Let's do our best, Tira」

「Put me down please」

「Now then, the last fight!」

「You definitely heard me, right!? Please, put me down! Fighting the last boss while being carried, isn't that embarrassing!」

「It's alright, no one is going to see it」

「My pride isn't agreeing with you, though」

「It's unfortunate, but my body won't operate without Tira being glued to me anymore」

「Don't say such scandalous things please!?」

「Also, Tira's sighs tickling the back of my neck, haahaa」

「Aren't you just a pervert then!? tte, don't block my butt with your hands when I'm trying to get down!」

「Tira-tan who gets excited by having her butt rubbed, haahaa」

「I'm not excited!」

「Ouch, hey, don't pull on my hair, I will go bald!」

「I will rip all and make you bald!?」

「Before that happens, charge!」

「Hiya」

I run up the stairs.

I bear with Tira's hair loss plan and arrive at the 100th floor.

We arrive in a spacious room.

A huge creature in the middle.

「Red Dragon! Apparently, that is this dungeon's last boss…… T, this is bad, the fire breath will come at us! The heat from Red Dragon's fire won't leave even a bone behind if we get hit! Please, quickly escape……」

「Yosh, Frontal breakthroooough!」

「Have you listened to what I said!?」

Soon, the Red Dragon's throat swells up and it spits burning red flame from its mouth.

I instantly kick the ground.

I move overhead the dragon with the jump's momentum.

「Oooooo!」

I hold my sword over my head and swings down at the Red Dragon with all my might.

Pakiiiin!

「tte, the sword has broken?」

「Red Dragon scales are harder than steel! Karuna-san, spare sword…… you don't have one…… ku…… As expected of the empty-handed Karuna-san…… let's retreat temporarily……」

「Yosh, let's fist it then!」

「Are you listening to me!?」

Because the sword is useless now, I hammer the Red Dragon with my fists.

Zugoon!!

A fierce blow strike resounds and the Red Dragon's large build vigorously slaps on the ground.

Blood gushes out from a large dent in the partially destroyed scale I hit.

「YOu have pulverized the Red Dragon scales with your fists――――!?」

Tira shouts in shock.

「Y, you, aren't you a swordsman!?」

「There are times where even swordsmen have to talk with fists」

「Although it has a proverb-like feel, I don't understand its meaning at all!」

「There's no theory. You feel it by heart. It's alright, once we are married for many years, the feelings will completely connect to you」

「We have met just a moment ago, right!?」

Maa, to be frank, because the sword was just a cheap, old sword, my fists have higher offensive power.

Of course, after pouring fighting spirit into my fists, I was able to destroy the scales easily.

「O, ooooo!」

「Oopsy, it's still alive. How tough」

The Red Dragon leaps with an angry expression.

But, at that time, Tira activates an Advanced Grade magic.

The Red Dragon is struck by a lightning.

「Gyaaaaaa」

The Red Dragon's body roasts while it screams.

The scales should have high resistance against magic, but because of the dent I made, the lightning easily flew into its body.

「You used Advanced Grade magic」

「Yes. The chant takes a while, but I did it. When Karuna-san's sword broke, I thought that it will need to be defeated with magic so I started chanting then」

「You did great beating my head and tsukkomiing while chanting……」

Quite skilled.

The Red Dragon dies and turns into ashes.

「Fuu. I'm glad I could be of use a little」

「No, you did a perfectly good job」

Rather, it was unexpectedly weak.

That? The last boss? Disappointing.

「Now then. Let's look for what's his face's data he left behind」

Then, at that time.

Tira suddenly firmly embraces me from behind.

「…… I see. Tira has accepted me at last――」

「W, wrong. Leaving that aside, o, over there……」

I look to the direction Tira points with shaking finger.

A ghost of an old man is there.

「…… Who are you?」

The ghost opens its mouth solemnly.

『――I'm Owen ja』

The creator himself has appeared, though.
