“【Titan’s Sword】!”
I created a super-gigantic [Dark Edge] while Vincent was momentarily stunned.
The 20 seconds of [Cooldown] for my Unique Magic [Dimension Leap] is my chance to damage Vincent.
“That giant sword is…!”
“Uooooooooh!”
Vincent retreated while deploying a Magic Barrier, but I didn’t care and slammed the [Titan’s Sword] down.
The surrounding buildings were blown away all at once. It was truly a giant’s strike.
Vincent avoided a direct hit, but he groaned as he was struck by fragments of rubble.
“Now!”
I switched my sword to the [Dispel Sword] and charged at Vincent.
“Don’t you dare underestimate me!”
Vincent roared, and the surrounding ground instantly froze over.
“[Ice Javelin]!”
Dozens of ice spears extended towards me from the frozen ground.
“Haaaaaaah!”
I used the [Dispel Sword] to negate every single ice spear.
However, because the ground had turned to ice, my dashing momentum was killed. The shaking of the underground cavern was getting stronger and stronger, and the footing was so bad that I couldn’t sprint at full speed.
“Did you see that? With your footing compromised, a swordsman cannot exert his power!”
“…Tch!”
He exploited the weakness of me being a swordsman, huh?
I thrust the [Dispel Sword] into the ground, and only the area around it was temporarily unfrozen, but soon the ice covered everything again.
The [Dispel Sword] can’t break his ice magic.
“It’s my win!”
Dozens more ice spears rushed at me again.
The moment I focused on defending against them, Vincent used [Dimension Leap] to teleport above me and brandished his [Dark Edge].
“[Hell Edge]!”
I created a magic sword by combining Diana’s signature magic, [Hellfire Barrage], with [Dark Edge].
It was a magic sword with a blade engulfed in black, cursed flames.
It was a new technique I had acquired as a trump card to counter Saint-Germain.
“What?!”
The cursed heatwave emitted from the [Hell Edge] shattered all the [Ice Javelins]. The ice covering the ground melted all at once, allowing me to regain my footing.
“To think it’s such a powerful magic sword…!”
Vincent’s [Dark Edge] collided with the [Hell Edge] and was incinerated.
He grimaced and tried to get away from me.
Enemies near this magic sword take continuous damage from the heat and curse.
“Think I’ll let you get away?!”
I switched to the [Hypnos’s Demon Sword] and tried to slash him.
The sword of non-killing that Mom taught me. If this strike lands, I win.
But at that moment, a part of the ceiling collapsed, and a large boulder fell directly above me.
“Whoa!?”
I guarded with the [Dark Edge Wall] in its large shield form, but in that gap, Vincent leaped back to create distance.
“Excellent, excellent! But you were unlucky!”
I immediately tried to pursue, but he used [Dimension Leap] to teleport to the roof of a distant building.
“I won’t underestimate you anymore. Out of respect, I’ll finish you off with thorough long-range attacks!”
“Guh…!”
I involuntarily clicked my tongue.
My weakness is that I can only fight in close combat.
I can fight at mid-range by using the [Titan’s Sword], but if he focuses on long-range attacks, I can’t reach him.
But I absolutely can’t give up. Diana is in this underground cavern too.
I remember the promise I made with Mom when I was little. I will protect my sister.
“Uoooooooooh!”
I charged fiercely towards Vincent.
I kicked off the ground with the recoil of creating [Dark Edge] from the soles of my feet, leaping high repeatedly to close the distance in one go.
“[Magic Arrow]!”
Vincent fired a barrage of magic arrows.
I negated all the light arrows that filled my vision with a dual-wielded [Dispel Sword].
“A [Dispel] magic sword…! I was surprised that you could synthesize magic you can’t even use, but you can’t defend against this!”
Vincent shot at the ceiling, causing a large amount of earth and rubble to rain down on me.
There’s no way to defend against this with the [Dispel Sword].
“[Dark Edge Wall]!”
I deployed the [Dark Edge] in its large shield form and held it above my head, forcibly pushing through.
But even though I had gotten close enough to Vincent to see the whites of his eyes, he used [Dimension Leap] to move to another location again.
“…Tch!”
An overwhelming predicament.
My Unique Magic and his were completely incompatible.
At this rate, I’ll run out of time and lose.
But at that moment, something suddenly flashed in my mind.
Vincent’s words just now…
‘You can synthesize magic you can’t even use’?
My Unique Magic is [Dark Edge], but other than being able to freely change its size and shape, it wasn’t that different from a normal [Dark Edge].
But since it’s called Unique Magic, it should have some other unique characteristic.
It was something that had been bothering me a little while ago.
I was able to synthesize [Hellfire Barrage] and [Black Lightning], which I shouldn’t be able to use, with [Dark Edge].
I didn’t know because there were no characters in the game who could only use [Dark Edge], but when I think about it, isn’t this abnormal?
Before, Mom, who taught me magic, was surprised and said, ‘Your synthesis magic is too special.’
When I asked her how it was special, she closed her mouth and wouldn’t tell me for some reason…
“…It’s a last gamble!”
Unique Magic is a gift from God that only one person in this world is allowed to use. But if it’s me, can’t I incorporate other people’s Unique Magic, which I shouldn’t be able to use, into [Dark Edge]?
Such an absurd idea came to my mind as I was cornered.
“[Dimension Leap] x [Dark Edge]!”
At that moment, I felt a strange sensation as if gears clicked into place in my head and started moving.
The incantation for Unique Magic is simple, just chanting the magic name.
“Take this!”
“Guh-ah!”
The blade of my [Dark Edge], which I swung, leaped through space and slashed Vincent’s shoulder.
“W-What was that just now…?”
Vincent, who was kneeling, stared in astonishment.
Vincent tried to escape further away with his Unique Magic [Dimension Leap].
“Think I’ll let you!”
But a moment faster than that, my—if I were to name it—[Dimension Edge] landed again.
This sword didn’t need a [Cooldown].
The blade that teleported from my hand slashed Vincent’s waist.
“A magic sword that incorporated my [Dimension Leap]!?”
His waist bag tore, and the stone tablet for collapse control fell out.
I charged fiercely and picked it up.
Vincent looked up at me, breathing roughly.
“Vincent, I win.”
“…What… What is this? Th-That power, it truly overturns the logic of this world…!”
When I tapped the stone tablet, the vibrations that had been attacking the underground city stopped.
“Has the collapse stopped now?”
Vincent was trembling, but he soon prostrated himself respectfully towards me.
“…Indeed. Our great ‘Prophesied Demon Lord’ sama.”
