I’m An S-Rank Behemoth Monster - Chapter 10 - Knight's Vow

Chapter 10 – Knight’s Vow

The next morning—

「Good morning, kitten.」

The elf girl greeted the behemoth with her gentle voice, waking up after the most restful night he’d had since he was born.

He was still deep in her embrace, just as he was when they went to sleep.

「Nyao~」

Punctuating his awakening with a yawning meow, the half-woke behemoth left his tiny body to its instincts, stretching against the elf’s breasts.

Munyumunyu, puripuri, purunpurun.

This was truly paradise.

「Fufu, what a cute little kitty. But I hope you’ll forgive me. Big Sis has to wake up soon.」

She released the behemoth from her motherly grasp, and lifted herself off the bed. The behemoth regretted having to give up those soft pillows, the feeling was immediately blown away.

「Whoop…」

Strip—

The girl slipped out of her translucent white nightgown, and a shiver ran down the behemoth’s spine.

They were black. The elf girl’s underwear was a solid black that he hadn’t seen in the darkness the night before. And more importantly, be it the brassiere above or the T-back below, their coverage was miniscule.

Her ample bosom. That tight waist. The minimalist garment that dared call itself a type of panties digging into her hips…

For any healthy man, this sight was to die for.

This girl…! For her to be wearing such indecent underwear, unbefitting her tidy outward appearance… Is it possible that she’s actually a slut? A neat-style slut?! More please!!

The behemoth was getting more excited by the second.

Just as he was wondering what would come next, a miracle happened before his eyes.

「Mm~~…—」

The elf girl… started stretching, hands held high above her head.

Boioioing—!

Her massive mobile melons bounced, the shaking surprisingly light for their size.

“Big breasts are packed with dreams.” Truer words have never been spoken.

He was convinced.

Following her morning workout, the girl continued changing her clothes, grabbing a set that was hanging on the wall.

The behemoth was experiencing the behemoth-level ordeal of watching this girl get dressed.

She somehow smoothly donned a form-hugging tunic that threatened to burst at the slightest motion and kneesocks that just barely squeezed her thighs.

From the way she talked last night, this girl’s most likely an adventurer.

That thought came to mind when he finally reached his first moment of clarity of the morning, shortly after the girl finished the alluring show of changing her clothes.

Her tunic exposed her midriff. Her short skirt was as flexible as it was fitting, emphasizing ease of movement. And a pair of high boots completed her attire.

But… including the underwear, that’s one hell of a provocative outfit for an adventurer.

True, the exposed part of her tunic was only her stomach. However, on the top side… her cleavage was sparing no effort in making her breasts’ presence known. Not to mention, the skirt was so short that he thought he would get a glimpse of her tender hips if she took even one step.

She also had two knives equipped, sheathed on either side. They were fastened against her belt, coiling right up against her appreciably plump rear end.

Hm, contrary to her gentle looks, she’s a vanguard.

Wait, vanguard?!

He knew by the knives that she was a frontliner, but that wasn’t enough for him.

After all, how could she possibly move like one with those flying around?

「Hmph, prep complete. I’ll see you later, kitten. Big Sis will come back soon, but I’ll leave the window open. You probably want to take a look around outside, right? Ah! And I’ll leave some milk for you before I go. I’ll get some from the auntie here.」

Before the behemoth could do anything, the door closed behind the girl.

Milk…

Hearing the word, the behemoth’s belly growled with hunger.

Soon enough, the girl returned with a saucer, milk included. He started drinking it as soon as she set it down, and quite loudly at that.

「Hehe, you were really hungry, weren’t you?」

Enjoying watching him for a little while, the elf eventually said her farewell and left the room. It was just him here now.

That girl saved me from the edge of death… And she gave me food and a place to sleep. And if what she said is any indicator, she even plans on looking after me from now on…

A warm feeling poured out of his chest.

I’ve decided! I will use this life of mine to serve this girl—no, to serve “Master”! Master’s an adventurer. As long as a behemoth like me is protecting her, even if she doesn’t know it, no dungeon will be a threat to her!

This was his resolve. And so, once more, he became a knight. Swearing his loyalty to the elf girl who saved his life, he would protect her to the bitter end.

I’ve gotta catch up to Master right away!

The behemoth leapt through the window leading to the city.
