The Protagonist's Sister Is Actually The Strongest

[“Do you think you can beat an A-Rank Monster like a Death Knight all on your own now, Anna? You’re getting cocky!”] Gram groaned.

“I beat that King Solomon or whatever he was called, right? He was S Rank; you dumb metal stick.” Anna sighed.

[“Who are you calling dumb metal stick?! Also, you were able to beat him, thanks to me! And also, you debuffed him through the roof! This is different; don’t tell me you’re going to use all your temporary buffs and debuffs to beat an A-Rank mob?”]

“I told you I wouldn’t!” Anna sighed.

“Your death shall be swift.”

A black blur appeared on the left side of Anna in a split second as a huge black sword quickly landed on her chest.

CRASH!

The mere impact blew her away, as she barely managed to reinforce her body with Ki to not break a rib. It also helped that she was wearing her new set of Angelic Armor she got from the Job Class Change Dungeon, which enhanced her physical defenses greatly.

[“See? You’re too weak for this yet! The Banshees were easy because you were mostly immune to their trump card, but this guy’s just physically strong!”]

“Shut up! It’s your fault because you distracted me!” Anna barked back, quickly deciding to ignore the annoying talking sword trope she hated so much from novels.

“Your demise is close.”

Another black blur appeared behind her this time; the Death Knight, despite his size and heavy armor, moved at an impressive speed. Anna gritted her teeth and evaded the descending black sword, which hit the floor instead.

“{Netherworld’s Flame Eruption}”

“Shit!”

However, it wasn’t just a descending sword attack; the Death Knight’s empty black eyes glowed bright blue as his black sword started overflowing with phantasmal flames that reached the floor below.

Crack, CRACK!

Several cracks spread across the ground, opening and erupting with phantasmal flames, constantly trying to catch Anna in their blazing embrace!

BOOM! BOOM! BOOM!

“Damn it!”

[The Effects of the [Little Rabbit’s Fearlessness (F Rank Privilege)] have been activated.]

[While running away from your foe, Agility increases by 50%.]

“Alright, he might be strong, but he’s still Undead.” Anna smiled defiantly, evading the explosions of phantasmal flames as her body started to gain a larger quantity of power.

[“Another buff?”] Gram wondered.

“Something like that. I guess it’s time to use that…”

Anna’s hand pointed at the Death Knight, and while she was gaining a buff, the Death Knight received a debuff! The best way for her to win these fights was by abusing the game-like system to her utmost advantage.

[The Effects of the [Death’s Little Sister (B Rank Privilege)] have been activated!]

[While fighting a Death-related foe or an Undead-type monster, your Stats increase by +50% and the foe’s Stats decrease by -25% for the duration of the battle.]

And this amazing Title she had acquired some time ago, which she mostly used to buff her Undead, had come in handy, as it held a special anti-undead ability.

The Death Knight suddenly felt weaker. “What sort of godly power…?! Ungh… Witch!” The skeleton glared at Anna even more furiously. “I’ll behead you!”

FLASH!

He immediately rushed towards Anna once more; this time, he had lost a fourth of his strength, and it clearly showed, as Anna no longer saw him as a blur of black color and could clearly see his body while he moved.

“{Sunlight Blade}! {Twin Cutter}!”

Anna combined the effects of her Sunlight Blade and her Twin Cutter Skills once more while clashing against the Death Knight’s sword.

Each swing of her sword generated two attacks at once, which, boosted by her Sunlight Blade skill, created two waves of cutting light. Its power was already obvious; it was even more effective against the Death Knight.

“Urgh!”

The skeleton was pushed back as he was forced to step back and reorganize his thoughts. His mind was moving rapidly despite being an Undead, showing he once used to be a seasoned knight, as all Death Knights were.

“She’s gotten stronger and faster, and I am weaker!” He thought. “Then… {Phantom Chains}!”

The Death Knight extended his hands towards Anna as phantasmal chains emerged, wrapping around her legs and arms and trying to restrain her!

“That’s not going to work! {Sunshine}!”

Anna’s physique resonated with her Sunshine Skill as a wave of Yang energy erupted from her body. The Phantasmal Chains were still weak to light, as they instantly dissipated the moment her light pierced them.

“{Decapitation}!”

However, that gave the Death Knight more than enough time to move behind her and raise his huge sword once more, aiming at her unprotected neck!

CLASH!

“Ungh?!”

Nonetheless, his attack failed, as Anna swiftly moved her free hand, raising her Glacial Wolf Fang Dagger and utilizing the Level 2 Dagger Arts Technique [Quick Parry], parrying a huge sword with her small knife thanks to the knife’s holy light element!

FLASH!

The Death Knight was covered by the light generated by his sword hitting the knife, giving Anna enough momentum to push her entire body against him and point her sword into his skull.

“{Celestial Slash}!”

Gathering Celestial Energy into Gram, Anna unleashed a powerful wave of the energy that Angels could wield, mixed with her Yang Ki and her Sunlight Blade Skill effects!

SLAAASH!

“Dammit…!”

The Death Knight groaned in agony as the slash went through his black helmet and left a huge crack in his skull, where Anna had detected his Magic Crystal. Once it was shattered, the Death Knight would instantly perish.

“{Phantom Burst}!”

Without wasting a single second, the Death Knight continued his struggle as his entire body erupted with phantasmal energy, his sword absorbing much energy as he leaped towards Anna, attempting to pierce her chest with his huge black sword!

The sword barely missed its target as Anna disoriented the sword’s trajectory using Gram while throwing her knife toward the Death Knight’s skull, where she had left the wound!

“{Phantom Chains}!”

The Death Knight desperately wrapped his chains around Anna’s arms, but it was too late! His empty eyes flared with phantasmal flames as the knife pierced his skull!

“Agh!”

CRASH!

His skull quickly shattered as the knife swiftly pierced through his magic crystal, shattering it into tiny pieces.

“Lady… Hel… Forgive… me!”

The formidable foe fell onto the floor, becoming the lifeless corpse it originally was, as Anna gasped for air, slightly exhausted.

“Hahaha… I did it!” Anna smiled. “With a few cheats, yeah, but I did it!”

[You defeated a [Death Knight (A Rank)] x1]

[You earned 100.000 EXP]

[Level Up!]

[“Honestly, I thought you would get your ass beaten.”]

“Ugh, your personality is really similar to Sepa! Do you get along?”

[“The bug? She’s still sleeping!”]

Anna ignored the bored sword, storing the Death Knight’s body and armor, his sword, and his Magic Crystal, as she decided to rush into the Undead Army with her sword and knife in hand.

“My death knight…!” The Lich groaned in frustration. “Kill her! Graah!”

He pointed his skeletal finger at Anna as the rest of the Undead swiftly started rushing towards her. The second Death Knight remained at the Lich’s side; it was clear he wouldn’t move from there, guarding his liege.

“Graaaah!”

The C-Rank Undead rushed towards Anna, trying to ignore her Angelic Spirit Knights, which only made Anna summon kill them with even more efficiency by attacking on their backs.

“Sorry, but I am not humoring you.” Anna began jumping from zombie head to skeleton head and then leaping high into the air, pointing Gram towards the Lich, and descending with it!

CRASH!

However, her descent was swiftly interrupted by the Lich’s second Death Knight, whose black axe easily intercepted Gram and then, with sheer physical strength, pushed her away. Anna was forced to leap on the axe itself and make some distance.

Perfect for the Lich.

“Hehehe, yes, stay right there, you False Goddess!” Laughed the Lich, his skull-decorated staff glowing with necrotic energy, exuding a wave of phantasmal energy. “{Graveyard of the Sinners}!”

“False Goddess?” Anna raised an eyebrow as she was called yet another new title she was not aware of.

Suddenly, Anna found herself surrounded by huge skeletal claws trying to grab her and drag her down to the ground. And there were dozens of them, coordinately trying to distract her, as the Death Knight swiftly reached her!

“Buddy, if I were you, I wouldn’t get too close.” Anna smiled. “{Sunshine}!”

The same eruption of Yang Energy came out of Anna’s Physique. Now that she had a lot of Ki and Mana, she thought that she could abuse this technique a bit more than usual.

The skeletons were instantly evaporated by her shining light, while the strong Death Knight was forced to retreat from her blinding, burning light. Anna quickly utilized the chance to attack him, swinging her sword by combining the [Sunlight Blade] and [Twin Cutter] Skills.

“{Phantasmal Smite}!”

The axe-wielding Death Knight gathered his energy into his huge black axe and released a terrific smite with it, clashing against Anna’s twin slash attacks and destroying them before they could reach him.

“You’re not bad at all! {Sunshine}!”

However, Anna simply gathered Mana and Yang Ki into her hand and fired out a huge beam of light against the Death Knight’s face!

BOOOM!

“Aakkh…!”

The Death Knight rolled over the floor, the shining light weakening him even more, on top of Anna’s Privilege as “Death’s Little Sister” which lowered his stats and increased hers while fighting death attribute foes.

“Urgh…! Lord Lich!” The Death Knight called for help.

“Fear not, my knight!” The Lich laughed. “I won’t abandon you so easily! {Helheim’s Claws}!”

Suddenly, two gigantic hands made of bones stuck together emerged out of the ground around the Lich, each as big as five meters! Anna stepped back as both claws flew towards her, floating in midair. Their sharp fingers attempt to pierce her body.

Her armor did her good; its shining brilliance held a nice amount of defense, and even as she sometimes received direct hits, it wouldn’t budge so easily.

“{Twin Celestial Sunlight Blade}!”

Fusing the effects of her Celestial Energy with Twin Cutter and Sunlight Blade, Anna unleashed two huge golden-colored waves of slashing divine power, hitting the two bone-made hands and completely evaporating one, while the other crumbled over the ground!

“W-Wha?! My Helheim’s Claws succumbing to this False Goddess?! {Phantasmal Fire}!” The Lich roared in frustration, conjuring a wave of phantasmal flames against Anna. At the same time, his Death Knight flew towards her, trying to strike her from behind while she was dealing with the Lich’s magic.

“{Decapitation}!”

His huge black axe descended towards Anna with enough force to surely slice through her armor this time! However, Violet appeared behind the Death Knight, slashing his back with his huge scythes, dealing almost no damage but changing his attack trajectory at the last moment!

“Nicely done, Violet!” Anna smiled, jumping over the Death Knight, who fell on the floor and pierced his skull with Gram! “{Sunlight Blade}!”

The sword channeled all her Sunlight Blade’s Skill power, shining brightly and blowing the Undead’s skull into pieces, alongside his Magic Crystal in there!

BOOOM!

[You defeated a [Death Knight (A Rank)] x1]

[You earned 100.000 EXP]

[Level Up!]

“M-My Death Knight!” The Lich groaned, quickly stepping back. “Dammit! How come you are so strong?! You’re merely a False Goddess! My Undead, attack her!!!”

The Lich started running away, trying to mix in between the rest of the Undead as waves of zombies, skeletons, and phantoms rushed towards Anna.

“Not so fast!”

However, Anna spread her Seraphin Wings and flew into the skies, charging Gram with her Ki and Mana and then unleashing a barrage of Twin Cutter and Sunlight Blade-powered slashes, which descended over the Lich, cutting him down to pieces!

SLASH! SLASH! SLASH!

“Aaarrggh!”

The Lich gave a last cry of agony before being completely destroyed.

[You defeated a [Lich (A Rank)] x1]

[You earned 100.000 EXP]

[Level Up!]

[Your Level has increased from Level 18 to Level 19!]

“Nice! I’m getting so many Levels!” Anna smiled with exhilaration.

RUMBLE!

However, her joy was quickly gone before the surprise she felt when she saw the ground below trembling and then a huge entity emerging from within.
