Chapter 05: What I Turned Away From

[Side: Betrayed Adventurer]

—Two days after causing havoc on the mountain, around the time the sun was directly overhead.

After crying my heart out and sleeping like a rock in that spot, I was now heading south toward the southernmost border of the Kingdom of Sildiel.

I’d soon arrive at the border town of Cahel.

“Should be safe once I get this far.”

I hadn’t stopped by any towns along the way from that mountain, nor had I gone near the royal capital or any of the main roads.

I didn’t know how Millia or the Hero might react. Would they try to contact me? Or maybe try to silence me?

Or maybe they wouldn’t even care about the man they had tossed aside.

Since nothing had been made public, they might not interfere much.

But the King and the people of the capital likely already knew about the relationship I once had with Millia.

Being an S-rank adventurer might attract attention.

“Millia…”

Just saying her name made my heart sink.

I felt sad. Hurt. But I wasn’t sure if I should be angry or cry.

If I could feel something as clear as “You betrayed me!” or “I’ll make you pay!” toward Millia, maybe it would be easier.

But with my mind all muddled, I couldn’t make sense of anything.

So for now, I decided that the best thing to do was to distance myself from Millia and the Hero’s party.

“No, no, don’t think about it…! I promised myself I’d stay upbeat, even if it’s forced!”

I shook my head, trying to shake off the dark thoughts.

Now, I was heading toward the southern border. The place where I received one of my swords was in a country to the south.

The border town of Cahel was about a ten-day journey by carriage from the royal capital, even when using the main roads.

But thanks to my magic swords, I’d covered the distance in just two days.

Using the blue magic sword Granchario, which controlled water and ice, I created a stream of water beneath my feet, and with the Piercing Wind Sword Breathslate, I manipulated the air.

By reducing air resistance in front of me and turning the wind behind me into a tailwind for extra thrust, I could travel at eight times the speed of a carriage.

I rode across the ground on a makeshift surfboard made from some cut wood, gliding at incredible speed.

It was like a human sailboat, inspired by surfing I’d seen in the southern countries. The only difference was that my acceleration had no real limit, as long as my body could withstand it.

By taking a straight shortcut instead of following the main roads, I’d managed to almost reach the border town in just over two days.

Even if the Hero’s party or the kingdom tried something, they’d be too far behind to catch up. I was leaving all that trouble behind.

Just a bit south of Cahel was a checkpoint, and beyond that lay a tropical coastal country.

That’s where I needed to go.

But before that, I planned to stop in Cahel… though…

“I’m starving, but I’ve got no money… Hopefully, the materials from that Titan Grizzly will fetch a good price.”

If I focused only on controlling my magic, I could keep moving as long as the sun was up, but over time, it drained a lot of my magic power and stamina.

On top of that, since I’d sent almost all my money to the Hero’s party, I was practically broke.

First, I needed money. And I really needed to rest.

“…Hmm?”

As I was moving through the grasslands near the main road, my magically enhanced senses picked up the sounds of a fight nearby.

A little further ahead, I could see what was happening more clearly.

“A wagon being guarded? Looks like three adventurers fighting five wyverns… tough fight.”

Although they were wearing hoods, their body shapes suggested the three adventurers were women.

They were well-coordinated, and they had already taken down two of the wyverns. Pretty strong—likely an A-rank party.

Magical beasts and animals were categorized by difficulty levels, similar to adventurer ranks.

A wyvern was classified as a B-rank threat when alone, but in groups, they could reach A-rank.

Their ability to fly at high speeds made them troublesome, but with the skills those women had, they should be able to handle it.

However, being outnumbered while protecting both cargo and people was a challenge. They had to guard not only the goods but also the horses and passengers, making things more difficult.

“…Guess I don’t have much of a choice. I’ll go help them.”

For adventurers, interfering with someone else’s request is generally a no-go.

But saving lives is more important. It’s an unspoken rule that if you can help, you should.

I released the magic controlling water and wind a bit further away from the battle.

As I landed, I used my magically enhanced legs to sprint forward at full speed.

“Need some help?”

“Y-Yes, please!”

The response came from a swordswoman wielding a longsword. Though her face was hidden by a hood, her voice was clearly that of a woman.

I dashed ahead, positioning myself between the wyvern and the wagon it was about to attack.

“Wait, four swords…? Hold on, are you—”

“Let’s go! Time to get fired up!”

Without energy and focus, you can’t even beat a bug! Time to shout and get in the zone!

The party leader said something, but that could wait. I lowered my stance, preparing for the attack.

I channeled magic into Breathslate in my left hand, causing sharp winds to swirl around the blade.

What I needed was a single, clean strike with maximum speed!

“《Wind Rush (Varia Sluster)》!”

A violent gust of wind condensed in a single point, giving me a tremendous burst of speed.

With Breathslate enhanced for a razor-sharp strike, I dashed across the grassland.

As the distance between us closed rapidly, the wyvern panicked and opened its jaws to bite me—but—

“《Wind Fang (Kazekiba)》!”

I swung Breathslate, now enveloped in wind magic, in a single strike. As the wyvern lunged to bite, I slipped beneath its jaws, dodging the attack, and sliced its skull vertically in two.

“Got it!”

Feeling the solid impact, I dashed under the falling wyvern.

The technique Wind Fang (Kazekiba), which sharpens the blade with wind, had enough cutting power to split even the hardest skulls in half.

“What…? It took down a wyvern so easily… I’ve really gotten stronger.”

Wyverns are fast, but when they attack, they have to get close. That’s when you can kill them in a single pass.

Once you get the timing down, it’s easy. If you miss, they’ll never come down again, so you have to finish them off with one strike.

“Let’s finish this quickly.”

Without slowing down much, I turned back and charged at the wyvern the woman had been fighting.

She had already sliced through its wing with her halberd, and it was trying to escape unsteadily into the sky.

“No way you’re getting away! Flying Swallow!”

Though I was a bit tired and sloppy, taking down a wyvern was no big deal.

With a slight effort, I swung Breathslate, still infused with Wind Fang.

—Sssssh!

As the sword cut through the air, the wind blade shot forward at high speed, decapitating the slow-flying wyvern.

Flying Swallow was a variation of Wind Fang, where the wind is unleashed as a flying slash.

“Now, let’s see… Oh, looks like it’s over.”

Glancing at the headless wyvern crashing to the ground behind me, I took stock of the situation around me.

It seemed the other wyverns had been dealt with—two had been killed, and one had fled in a hurry.

Once their numbers dropped, the battle ended quickly. As expected, they were strong.

The real challenge had been the numbers and having to protect the wagon, but with fewer wyverns to deal with, they were able to finish the fight in no time.

As I sheathed my sword, the female swordsman I had spoken to earlier approached me.

She had a slim, well-toned physique.

Compared to Millia, who I saw yesterday, she had less muscle mass, with a body that seemed refined and built for function.

“Thanks, you really saved us. You’re still unbelievably strong, huh?”

“Ah, don’t mention it… ‘Still’?”

“Hehe… It’s me, Abel!”

The leader of the party, now standing close to me, pulled back her hood.

Revealed beneath was a blonde woman with long hair trailing down her back, and a lively, friendly smile.

She had large, expressive eyes and an energetic, cheerful expression.

I was shocked to see her face—it was someone I had known for years, ever since I left my village for the royal capital.

“…Wait, Elmie? No way!”

“Yep, it’s really me! Elmie from back when we were just newbie E-rank adventurers!”

“Wow, it really is you…!”

“What’s with that reaction!? You should be saying, ‘I’m so happy to see you! Elmie, you’re so cute!’”

Elmie laughed teasingly, with the same bright energy I remembered. There was no doubt—it was the Elmie I knew well.

I had met her when I first came to the royal capital.

She was a year older than me, and since we were close in both age and adventurer experience, we often teamed up when Millia was busy with school or other things. We became good friends.

“So, those two over there must be…?”

“Ufufu, it’s your big sister, Abel~!”

“Hey there! Long time no see, Abel!”

The other two also pulled back their hoods, revealing mature women with striking dark purple hair.

They both had identical faces and were smiling as they each took hold of my hands.

The one who called herself my “big sister” was the laid-back older sister, Frey.

With her wavy hair and gentle appearance, she was the one who had been swinging that halberd around earlier.

Her calm demeanor didn’t match her powerful strength.

The more energetic one, who was shaking my hand and moving excitedly, was the younger sister, Maria. She had straight hair.

Unlike Frey’s droopy eyes, Maria had slightly larger, rounder ones.

She was skilled, using several different weapons during the fight.

These two were twin sisters who had been part of Elmie’s party since back then.
