Reincarnated As The Hero’s Daughter: Wait, Why Is My MP Not Running Out?

CLAAASH!

My brother attacked me without holding back, and so, I responded with the same intent. I released my Yggdragon’s Dual Aura at full power, releasing a powerful shockwave of Flames and Nature Spirit Essence that quickly sent him flying.

"Uwaah!"

He screamed in surprise as he found himself high into the skies. But that shouldn’t bother him if he had wings to begin with. I swiftly flew into the skies right where he had reached, using my own Dragon Wings.

FLASH!

My wings released bursts of crimson flames to aid me reaching higher into the skies. At the same time, my body started to quickly grow tougher as lightning began coursing through it.

"Zephy, prepare yourself! Big sis is not holding back anymore!"

"Y-Yes!"

As I rushed towards him with my lightning sword, Zephy responded by imbuing his Dual Aura into his swords, crossing them and using them to defend himself from the incoming attack.

"ROOOAARR!"

My Aura erupted, resembling a mighty dragon made of red, green, and gold lightning, opening its jaws, it clashed against Zephy at the same time as I swung Scarlet against him. CRAAASH!

A thunderous explosion reverberated the skies, as I heard my friends and family down below panic. My mother had a very worried expression, while my father was simply nodding as he watched.

Yet...

"Hahh...!"

Zephy responded at the same time as my attack hit and engulfed him on an explosion of electricity. His two swords suddenly flashing with power, as I sensed his Dark and Blood and Holy Golden Flames combining together with his two swords.

"{Eclipsing Dual Sword Arts)}: {Moonlight Cleave}! {Sunlight Slash}!"

Both of his swords shone with different auras, one resembling the silver and purple color of the moonlight, the other the radiant gold of sunlight. Both attacks came spinning against me, as I, for a moment, could swear I saw the moon and the sun surging and hitting me with all their force.

CLASH! CLASH!

I was pushed down by Zephy as he continuously unleashed a barrage of slashing attacks, each attack released an explosion of sunlight and moonlight.

I never knew he could combine elements like that and recreate Sunlight and Moonlight in such a creative way!

"Not bad, not bad at all, little brother!"

I responded against his passion and strength with my own power. My Divine Thunder further combined with my Dual Yggdragon Aura, as several dozens of serpent-like dragons appeared one after another from my Aura.

"{Divine Thunder Dragon Blade Arts}: {Lightning Serpent’s Thunderstorm}!"

CLASH! CLASH! CLASH! CLASH!

Each of my slashing blows released explosions of thunder, flames, and nature energies as the serpents exploded, guided by the swinging of my sword. Zephy resisted the damage as he used his Physique’s amazing regeneration to somehow keep up with me.

But not for too long. As he prepared a dual wielding technique, I quickly pushed my body towards him and twisted him down, right below me before I charged my sword with flames, Ignatius’ Spiritual Powers overflowing through it.

"{Divine Blazing Dragon Blade Arts}: {Volcanic Dragon Fangs}!"

SLAAASH!

With a single slash of Scarlet, my Aura erupted as an enormous dragon jaw was summoned, made of volcanic magma and flames, quickly engulfing Zephy completely, as I saw him encapsulating himself with his own wings before he impacted the ground with a loud, blazing explosion.

BOOOMMM!!!

The ground below us instantly burned and melted, the plants caught fire, burned, and turned into ashes within seconds. Everything around us had become a hellscape out of nowhere.

My abilities were truly destructive, and that’s saying something when I was limiting myself to only using sword techniques, no skills or familiars.

"Hahh... Hahh... Big sis... Big sis’ so strong!"

Zephy slowly stood up, even as his surroundings burned and his clothes were slightly tattered, he looked to be still willing to fight more, even as his body was covered on burnt wounds that he slowly tried to regenerate with his golden flames, possessing a healing effect. "This is me going all-out, Zephy." I said. "You can only keep up because of your regeneration abilities, but that only works based on your Mana quantity and Stamina. Once you run out of that, you’ll lose. Are you sure you want to continue?"

"I am!" He nodded, his eyes blazing with conviction. "I need to do this, to show mama and papa, and big sis... And Celica! That I am strong too!"

"Zephy..." I noticed the bravery and conviction within his eyes.

Despite how much we loved him and gave him all the attention of the world, he still developed some sort of inferiority complex. Perhaps because of everyone in the family being so strong already, and him not catching up.

And that’s without mentioning all the times both friends and family mentioned how strong I was at his age, it slowly created this feeling of inferiority, of wanting to show off how strong he was...

"You don’t have to do this, Zephy! We know you’re strong! You’re amazing just like you are!" I

Said.

"No big sis, that’s not enough..." He sighed. "I-I need to get stronger, for the future too..."

"The future?" I wondered.

"Maybe one day... You’ll understand." He said. "But for that future, and for everyone, I need to get stronger, and this fight will help me breakthrough! I have to do it no matter what... So

Please, bear with me!"

FLUOSH!

It wasn’t just Zephy’s conviction and his inferiority complex, there was something else there, something driving him.

A future he wanted to protect.

I don’t know why, but when I saw his Aura surge from his body at full power, even I felt

Slightly afraid.

A gigantic entity, a monster, a demon, something with countless arms and eyes, and horns

And wings, and tails...

The embodiment of his Aura, of his Darkness and Blood Energies.

We didn’t know what it was, but it looked like the true manifestation of his Beast Aura.

A giant.

Was this... his true power, his true potential?

"RAAAH!"

With a furious yet cute roar, my little brother rushed forwards, his Aura enchanting all his physical capabilities, as both of his swords absorbed his power, suddenly transforming.

Both swords became pitch black, with red runes and jewels, with sharp, horn-shaped handle

Decorations.

Did he just summon his Soul Weapons?

CLAAASH!
