Reincarnated as a Son of the Sword Saint and the Sage



The monster in front of us was immensely huge and was the real definition of a kaiju. With a length of around one hundred fifty meters, it could easily outsize Czarina's majestic dragon form, which was a hundred meters in length. 

From a distance, Big Sis and I were like a pair of little mice compared to the Apex Saurian. That was how huge it was. But according to Akashvani, the one before us was still a juvenile and was not fully mature yet. I wonder how big these creatures really are.

But no matter how big this monster could be, it was still a monster, a being who, most of the time, acted based on its instincts. To top it all, it was not as strong as our parents, so we were both confident of beating its ass. 

"Sky Tearer." 

Covered with a purplish cloak of dazzling lightning, I slashed my new katana, which I named Vermeil Lily, diagonally at a tremendous speed and released a Level 9 technique. 

We had been fighting the monster for several minutes already and had inflicted countless wounds all over its body. Even though we said to kill it as soon as possible, we had been constantly damaging it with only swords, no magic, and no skills. 

My sister said that it was because it was the best opportunity to test her sword to a certain extent. The previous Guardians were not this tough, except for the Beastmuth, of course. She could not use her sword that time, so she wasted no time using this kaiju as her guinea pig. 

A huge wave was released immediately after my slash, and it flew toward the chest of the kaiju, which carved a deep wound afterwards. 

Shriek!!! 

The Apex Saurian then cried in agony when I did the art on its chest. In response, it faced down to where I stood before it opened its mouth and unleashed a fire Breath Attack. 

I could have avoided it, but I decided to take it head-on since it was not that powerful to begin with. I deployed defenses around myself for additional protection, of course. 

Although it was not clear, I could see that the kaiju was kind of perplexed upon witnessing its attack, which did not seem to damage or even affect my body. And without warning, Big Sis then suddenly appeared midair on its back and executed the same technique as mine. 

"Sky Tearer!" 

Shriek! 

The extremely sharp and fast wave hit the kaiju's back and caused damage to its tough skin and glowing dorsal plates. The slash was probably so painful that the monster got on all fours. 

Suddenly, the atmosphere around the Apex Saurian changed. The flow of mana within its body became thicker and denser than before. Eventually, the hue of its dorsal plates turned from red to white until it became bluish-white in the end. 

The kaiju had ultimately activated the Blue Flame, which greatly increased the temperature of its fire attacks. Due to the change in its appearance, it was safe to say that this kaiju had turned into a real Gojira, except it did not possess any nuclear powers. 

"Shriek!!!" 

After it increased its firepower, the Apex Saurian stood back and let out a deafening roar. Once it recognized its target, it quickly turned around and used the Scale Shot to fire a few of its dorsal plates at me. 

I saw each of the plates, and I easily predicted their trajectories. With just a single fluid swing of my sword, all the plates were cleanly cleaved in half and did not land on my clothes. 

After that, the monster next turned its attention to Big Sis, who was standing on the obsidian surface behind it, and cast a large Level 4 Fire Lance fueled by Blue Flame at her. 

My sister immediately avoided the attack by dashing forward. The bluish lance of flame was definitely so hot that it melted the obsidian and struck into it. Even Big Sis would not be left unscathed if she were to take that spell head-on.

As she dashed like lightning streaks, she began to pour into her Midnight Raven a large amount of her fighting spirit, which then manifested into the form of a stupendously large energy sword. 

Holding the grip with both of her hands, my Sister raised her sword overhead before she swung it down with her mighty strength once she got several dozen meters from it, a distance far enough for the tip of her extended sword to harm the kaiju. 

"Heavenly Strike!" 

Due to the purplish lightning streaks cloaked around her lean and sexy body, Big Sis swung her sword so fast that the kaiju could not follow her movements and let it slice through its body. 

At the start, the Level 10 Sword Art technique began its journey at the chest. The technique effortlessly went through its tough skin and easily penetrated its ribs. It sliced its belly and cut deep into its internal organs before exiting at the crotch. 

"Gwwwaaarrrr!!!" 

Once the tip of the extended blade was deeply buried into the obsidian floor, the Apex Saurian stepped back, screaming in intense pain. Blood gushed out of the cut that painted the glossy surface as it swaggered. 

"Haah..." After exhausting her mana again, Big Sis kneeled down with the blade supporting her. "Finish it off, Raphael!" Her voice echoed. 

"I got you, Sis!" 

Motivated by her cheering voice rooting for me, I held my sword with both hands and bent my knees to take a stance. As I waited for the agonizing kaiju to turn toward me, I began pouring a portion of my mana into my sword. 

My mana thickly concentrated around my sword, and its hue turned purplish-black afterwards. The crying monster finally turned its body and faced my direction, which was the moment I had been waiting for. 

"You cheap knockoff. Taste the power of your otherworldly counterpart." 

(This monster might be the original, though.) 

Holding my magically concentrated sword, I started utilizing the power that I got from Inari. With the help of the Unique Skill: Mystic Artist, I had the capability to use a magic spell and technique at the same time. 

Therefore, I was able to endow the attribute of World Magic Level 6: Atomic Age into Sword Art Level 9: Sky Tearer to create a new kind of attack, which I named...

"Nuclear Wave." 

The moment I swung my sword diagonally, a huge purplish-black crescent-shaped wave was released from it. It flew so fast toward the terrified titan and effectively hit its body without a second's delay.

The dark wave went through its body like a ghost and passed the body before hitting the black walls. Immediately afterwards, the body of the massive Apex Saurian was cut in half. The part where the Nuclear Wave touched had been disintegrated atomically. 

Crash!

With a loud crash, the upper half first fell onto the surface before the lower half tumbled. A few seconds after its body was cleaved in half, the kaiju stopped breathing and its heart became beatless, and then the system officially declared it dead. 

"Whew." 

I disabled the Atomic Age and then sheathed my sword back before opening my Inventory to collect the gigantic corpse of the kaiju. Once I was done, I used Warp and then teleported myself to Big Sis, who was hundreds of meters away from me. 

"Raphael..." 

Once I got in her spot, I immediately raised her up. I gave her a warm hug for doing a pretty good job. Of course, I could not forget to kiss her lips to reward myself. 

"Oh, Sis. You are all sweaty." After a pause, I took a sniff on her sweaty and absolutely smelly neck with closed eyes. "But I love it." 

"You pervert..." 

I was not satisfied yet, so I sniffed her more. She just calmly let me do whatever I wanted to do, and I took the opportunity to rub her tits. 

"Okay, Raphael. Let's get out of here immediately after we claim our rewards." 

"Of course, Sis. But let me do you before you take a bath. It's the scent, Sis, the scent." 

"Hmph. I really can't understand your fetishes." 

As we were clattering, the reward chest then surfaced in the middle of the island. We took our loot and went to the mansion on the 60th Floor after that.
