Isekai Adventure in the Dimensional Cube

In the world-famous legend of King Arthur, the Round Table Knight Gawain is renowned for his combat prowess, which is completely on par with the one known as the strongest Round Table Knight, Lancelot.

His swordsmanship is exceptional, his strength unparalleled, and he has also received the Sun’s blessing, being endowed with the blessing of the saints, making him invincible under the noonday sun. Even Lancelot, known as the strongest Round Table Knight, must delay the fight until sunset to have a chance to defeat him.

This Gawain, too, like King Arthur, received a holy sword bestowed by the fairy of the lake.

It is the same holy sword as that held by King Arthur, the sister sword to the King’s sword, corresponding to King Arthur’s holy sword, which is blessed by the moon, having the sun’s blessing, and even containing a simulated sun at its hilt—an authentic Daylight Sword.

This is the Sun Holy Sword of the Round Table Knight Gawain—Calvin.

And the magic sword held by Bagster is precisely the Round Table Knight Gawain’s holy sword, modelled after her own "horn," known as the Burning Antenna—Fairy Sword·Calvin.

Though not a true holy sword, the antenna growing on Bagster’s forehead is proof of her ancestral return to the lineage of Arling, constantly suppressing Bagster’s own spiritual foundation growth. Once it is removed, Bagster’s rationality will completely vanish, causing true ancestral phenomena, making her a current Arling, with her body and strength exponentially increasing under planetary power, ultimately transforming her into a true monster capable of destroying the earth with a casual strike.

The Fairy Sword·Calvin, simulated with such a "horn," might not surpass the true Sun Holy Sword Calvin in rank, but in terms of sheer power, it might not be inferior at all.

However, it was precisely such a demonic Fairy Sword that was cut in half today by someone.

"Bang!"

With a sound resembling shattering glass, the broken blade of the Fairy Sword·Calvin fractured further.

"Ugh...!"

Bagster, resembling a maddened dog, involuntarily knelt on one knee, with half of Calvin embedded in the ground, supporting her body but showing signs of falling.

At this moment, Bagster was drenched in blood, vomiting mouthfuls of it, and bearing a hideous and terrifyingly large knife wound that nearly sliced her in half, exposing bone.

The surrounding flames seemed to lose power due to Bagster’s severe injuries, extinguishing at a visible speed, causing the raging sea of fire to slightly calm.

"Lady Bagster!"

"How could this be...!?"

The fairies of the Tusk Clan, feeling fear from the calming sea of flames but still observing the battle, widened their eyes in disbelief at this scene.

"Woof!"

"Woof!"

The black dogs surrounding the area, akin to being provoked, recklessly charged forward, attempting to overwhelm Reiger, standing not far from Bagster, with a sea of dogs tactic.

However—

"Splat!" "Splat!" "Splat!" "Splat!"...

The large splashes of blood shedding from Bagster’s body suddenly seemed to come to life, transforming into sharp spikes at incredible speed, erupting in all directions, morphing into a massive blood-colored sea urchin, instantly piercing the incoming black dogs on each blood spike.

"Boom!!!"

Simultaneously, a grand beam of magic power descended from the sky, shooting forth from afar like a laser cannon, sweeping the earth around Reiger, shattering the ground into flying debris, while blasting the surrounding Tusk Clan fairies, clearing all the minor enemies around Reiger and Bagster.

"Have they come?"

Reiger was not surprised by this; instead, a slight smile curved on his lips.

"Reiger!"

At the same time, a complex voice containing surprise, repression, and other emotions sounded, reaching both Reiger’s and Bagster’s ears.

A fairy girl attired in academy-style mage uniform, holding a designated staff, finally reached the battlefield and joined in.

It’s just a pity, she came too late.

"Bagster? You...?"

Originally focused only on Reiger, Altoria noticed Bagster drenched in blood, kneeling, with a terrifying knife wound, holding the halved Fairy Sword·Calvin. Her rush was halted immediately, her eyes slightly widened, just like the Tusk Clan fairies, unable to believe her eyes.

Not just her, but Fujimaru Ritsuka, Matthew, Alberon, Da Vinci, and Pasival, arriving on the scene subsequently, all gazed at this scene in shock.

"You, you’re Mr. Reiger?"

Matthew looked at Reiger standing before Bagster, showing a mixture of surprise and delight.

"You’re back?"

Da Vinci was also somewhat delighted and seemed to understand what had transpired.

"So it’s you who returned, Reiger!"

Alberon shouted dramatically.

As for Pasival, the fairy girl wielding a knight’s lance, and the small, almost child-like fairy girl, their reactions varied.

"Is he the one who replaced Altoria before, operating in Britain as the prophesied child, becoming the queen’s consort, recognized by ’that person’ as a human?"
