With his new burst of speed, Sakyo goes right under the wyvern's huge frame. He gets Uramasa into slashing position, aiming the dull side of the blade right to the wyvern's stomach. With one swift motion, he slashes upward with full force.
[Sakyo] {Auratic Pulse}!
The wave of energy forces the wyvern off the ground in an instant. Both Garm and a barely conscious Naja go wide eyed as they see the huge figure take to the sky without its wings. They can barely process the sight before seeing Sakyo's blur leaping even higher.
[Sakyo] Just this once, I'll use both your powers together. Both aura and miasma, let's see what you can do.
He turns Uramasa's blade to the sharp edge for the first time. The mere action causes a surge of power to flood from it. The very same crushing pressure that he felt the first time he claimed the sword.
[Sakyo] This is it. One strike and it's over. If Uramasa doesn't have a move to kill this thing, then I'll make one.
Sakyo gathers every ounce of power into the blade. Shadows begin leaking out from it, the raw power becoming too great to suppress much longer.
[Sakyo] Take this! {Hōgyo (崩御) Reversal}!
One slash at full power. No one could believe their eyes. There wasn't a grand sound. Only a wave of energy slashing even the ground so far below them. Blood spews from the wyvern as half of its body is cleaved right off. Its body falls to the ground followed by its left limbs shortly behind it.
As its limbs fall, its severed wing descends right for where Sakyo placed Naja to rest. He can't get to her in time. Not from up there, but he doesn't need to.
Even with one leg, Garm moves as fast as he can. With one hand keeping him balanced, he grabs Naja on his back and carries her out of harm. The wing lands right behind them, blowing both siblings away with a powerful gust. Meanwhile, Sakyo watches from high above.
[Sakyo] He got her... Good....
His consciousness fades from the use of so much energy. He'd had both his mana and aura drained before, but nothing could compare to this. His body falls unconscious as its descent increases in speed.
[Garm/Naja] Master/Boss!
They cry out, but neither of them have enough strength to catch him before he'll hit the ground. As they panic over what to do, Lumi leaps out of the shadows, running through the sky with every bit of strength she has left. Sakyo's body lands on her back as she brings him back to the ground before collapsing into his shadow.
Garm crawls towards him, Naja limping shortly behind. She picks up Sakyo's head, placing it on her lap. Even after everything they'd been through, she can't help staring at his unconscious face.
[Naja] Why did you save me? I thought I was no longer your sister.
[Garm] (sigh) I do not think of you as such, but I cannot deny that you mean something to Master. That attack was meant to kill you, yet he shielded you with his own body before knowing I stayed behind to help him. Though I hate to admit it, you are one of his mates. He clearly loves you.
[Naja] ...since I submitted to him.
[Garm] What?
[Naja] I have not made a report home since that day. Father does not know where Raynemor is located, or that I have become one of Boss's...that I am Sakyo's mate.
[Garm] I see.
[Naja] At first, I only admired his strength. I only submitted to him to save myself, but now... no, even before now, I have already fallen in love with him.
When he looks at her, Garm can't ignore the lovestruck look in his sister's eyes as she looks at the one she adores. Seeing her like this, he smiles, knowing that there might still be hope for his sister.
[Garm] I have never seen that look on your face before.
[Naja] Hm? What look?
[Garm] That blush. You look as if you want to begin mating with him right away.
[Naja] Wha-... Tha-... I-....
She can't find any words to deny his. Her blush only serves to prove his point. He's right. Every instinct in her body is telling her to conceive with her mate as quickly as possible, but she holds them back.
[Naja] I am his third mate. There are still two who must have his children before me.
[Sakyo] Ughhhh...
[Garm/Naja] Master/Boss!
Sakyo slowly regains consciousness, unknowingly holding Naja's tail in his arms. Though he's waking up, his body is still too exhausted to fully lift itself.
[Sakyo] ...Is it over?
[Garm] Yes, the wyvern is dead. You defeated it.
[Naja] That attack was incredible. You cut it in half with one strike.
[Sakyo] I'm glad. Are you two ok?
[Garm] My prosthetic was burnt by its fire breath, but otherwise I am fine. In fact, I feel better than I have in a long time. Perhaps my siblings can finally rest easy knowing that monster is finally gone.
[Naja] I am better as well. My wounds need a bit of covering, but I just require rest.
[Sakyo] Good, I don't know what I'd do without you two.
He pets both of their heads, causing them to blush together. After finding his strength, Sakyo stands up and walks over to the wyvern.
[Naja] What are you doing?
[Sakyo] Just getting a little something. (I got all of the miasma this thing had, but I want to get its soul too. Something this strong should give me a good power boost.)
He extends his hand towards the wyvern's corpse, ready to feel a new power flow through him, but instead...
System: [Notice: {Wyvern Soul} contains too much power to absorb. Due to limited ability, {Wyvern Soul} cannot be absorbed.]
[Sakyo] What?!
[Uramasa] (It would appear you have limited room in your soul corridor.)
[Akuma] (Looks like you're not strong enough to live through the backlash from even this mediocre being.)
[Sakyo] We fought this thing so hard, and I can't even absorb it?!
[Uramasa] (Perhaps I can offer a bit of assistance, but just this once.)
System: [Notice: Due to interference of {Uramasa}, {Wyvern Soul} is being converted. {Wyvern Soul} has successfully been converted into {Wyvern Geist}. {Wyvern Geist} has been added to your list of summons.]
[Sakyo] What did you just do?
[Uramasa] (Just watch.)
From the bloody remains of the wyvern rises a large shadow in its shape. No signs of damage. No scars or wounds. The shadow looks as if the wyvern was created anew.
[Uramasa] (As you saw when we first met, I hold domain over shadow warriors. Consider this a gift for letting me feast on such power.)
The Wyvern Geist roars loud. Its screech echoing throughout the entire land. Looking up at his new summon, Sakyo can't help but smile.
[Sakyo] Now this was worth it.
Meanwhile, hiding behind a group of trees just outside the village stands three adventurers who can't even begin to comprehend everything they just saw.
[Dreg] What the hell was that?!
[Risa] I thought that brat was just supposed to fight a Manavore, not a wyvern!
[Hobrin] And to top it off, he turned it into some kind of shadow beast!
[Dreg] This brat's not some stuck up noble, he's a monster.
[Risa] A wyvern like that would normally take a small army to deal with, but they just had three people who didn't even use magic.
[Hobrin] And what was that last attack? He cut that huge beast in half with one slash.
[Dreg] I knew that sword wasn't normal, but I didn't think it was strong enough to kill an A-rank monster.
[Risa] What do we do now? I thought we were going to ambush him after he fought the Manavore, but if he has that thing now...
[Dreg] We're leaving.
[Risa/Hobrin] What?
[Dreg] That brat-... that young man was able to kill something we would've needed to run away from. If you think we could fight him without risking our lives, be my guest.
They all share the same look. A look that says they can't win against him.
[Hobrin] Still, just how far do you think that kid can go?
[Dreg] If he keeps going down his own path, he'll reach A-rank before long. He might even become the first S-rank in three years.
[Risa] S-rank. That's something I never thought I'd hear. The last one was that Amazonian woman from the west of Virelya.
[Hobrin] The Holy Kingdom? I though most amazons lived closer to Raefauna.
[Dreg] It doesn't matter, let's just go back to the capital. The kid's gonna need some witnesses to prove he actually slayed a wyvern.
[Risa] Softie.
[Dreg] Call me what you want, but even I have to give credit where it's due.
With their original plan completely given up, the three adventurers leave the village without a word.
...
Somewhere far away, in a secret lab of unknown location, three scientists stand around a single mage. The mage is thin, looking like it's been weeks since their last meal. He keeps a swirl of magic open. Peering into the magic gives a clear view of the village the wyvern attacked. The first to speak is the skinnier of the two men wearing a coat clearly too big for his thin frame.
[Luro] (sigh) I knew that beast wasn't ready yet.
[Onslow] If it died so easily, it was a failure to begin with.
The broad shouldered scientists answers first, clearly disappointed that his favorite subject died so quickly.
[Luro] You were the one who insisted we send it on this task. I wanted to keep researching it before sending it out.
[Onslow] It was just supposed to retrieve that sharp toothed bull. Such a task should've been easy for it to accomplish.
[Luro] No matter, I suppose there's no point fretting over it. That beast probably burned any funding we could've made from that village anyway.
[Onslow] I guess this test was a failure. I'll just get back to training the other subjects.
Before he can walk away, the third scientist, a tall woman with long pink hair tied in a ponytail, takes note of something.
[Martha] I wouldn't say this was a complete failure~.
[Onslow] And what makes you say that?
[Martha] That boy. You saw what he did, didn't you?
[Luro] The black haired one. The way he moved. The power he used. There can be no mistake. He not only sensed it, but even absorbed and used it himself.
[Onslow] He used miasma? That's impossible. He doesn't match subject HD-09 or P-35, and he's too young to have escaped the lab during the riot twenty years ago. He couldn't be one of ours.
[Luro] He may not be one of ours. He was somehow able to absorb the beast's miasma without losing control to it. It's possible he is a natural born.
[Martha] Whatever he is, it seems we may have found The One we've been looking for~.
