Biography

Kaden's Discovery of the Champion Sword

Prior to his eventual turn, the Hero Kaden was tasked by the Gods to find the "Sword of Light", the Champion's Sword.

After he managed to acquire the sword, he began to read through the sword's memories, where to his surprise and confusion, the memories within the sword were that of the future, in which the Guardian gathered the Champions and defeated The Savior, but then there was nothing.

He began to research the memories of the sword by reaching further into the memories, looking for something that could justify why the sword would have memories of the future, that's when the Plague Doctor appeared to him.

The Plague Doctor informed Kaden of the truth of this world, which led Kaden to believe that reaching that truth would allow him to save the world, and he began his research.

Sometime after, he and his companions ventured out to the Motori Mountain to discuss about the Champion's Sword with the head of the soul mage family at that time, before leaving.

After continuous research into the matter, Kaden became desperate and started to wonder if the truth was even reachable, and if it was even possible to save this world.

Sometime after, Kaden learned about the seeds of a flower made of Labose, though was initially skeptic about its existence.

Though later on, he discovered the seeds, and began to devise a plan to use the flower as a way to break The Loop.

He also learned that in order to sprout the seed, he needed someone who "had reached rock bottom emotionally and is currently struggling".

Lili, the Queen of Kanterbury later found out about it and told him that the flower he found wasn't the answer, and that the flower would end up turning him into a monster.

She continued by saying he should instead stand with her and the heroes of the next generations in their fight against the threat of the future.

Massacre on Heavenhold

He visited Clara one last time, telling her that he had no other options left.

He later visited Heavenhold, donning a new outfit and throwing away his old armor, before summoning numerous Labose monsters within the floating playground, killing all of its research team alongside Loraine, leaving Vinette the sole survivor.

After blossoming one flower using the mana extracted from the dead corpses, he began his Labose experiments, eventually disappearing with no trace left behind, causing the diplomatic relationship between Demon World and Human World to strain, leaving Heavenhold's ownership in dispute.

First Recorded Appearance

Kaden later secretly reappeared, under the moniker of the "Plague Doctor", with his first recorded appearance in Tetis dating back to 103 A.H, where he is described to be a figure who "grants your wishes but takes away your soul".

He appeared in front of a boy, who was enslaved after losing his family.

The same night, the boy was given a sword, which he used to slaughter everyone within the city that he was living in.

When the city's army arrived, the boy had already died, leaving no survivors.

Revisit to Magic School

On 502 A.H, the Knight retrieved all pages of Laura's diary for an occult-obsessed student, who ends up being possessed by Laura, a Magic School student who was manipulated by Kaden into slaughtering her classmates, after her spirit was freed due to the pages being gathered in one place.

The Knight battled against Laura, emerging victorious at the end, before Kaden appeared right next to Laura.

He then tells the Knight that they'll meet again soon, before disappearing.

Missing People

The Plague Doctor later visited Demon World's Commuter Town, where he started to use the townspeople as subjects for an experiment related to Labose, starting a mysterious incident where people around Commuter Town begin to go missing.

He later approached a restaurant owner, asking him what his wish was.

Thinking that it was some sort of a joke, the restaurant owner told him that he wished for his restaurant to be the most popular within the town.

Telling the restaurant owner that his wish has been granted, the Plague Doctor vanished into the crowd.

After the restaurant became famous, the Plague Doctor came back to the restaurant and took over the owner's identity, by disguising himself as the restaurant owner and locking the actual owner inside a room within the restaurant.

The Knight later visited the restaurant, where they meet with the Plague Doctor again after they discover the owner's location.

Telling the Knight about his experiment, the Plague Doctor used the Labose infection on the restaurant owner, turning him into a monster.

The Knight was able to defeat the infected restaurant owner, bringing him back to his original form.

The Plague Doctor then tells the Knight that they'll meet again, and to take care of the Champion Sword until it happens, before fading away.

Visit to Demonshire

The Plague Doctor arrived at Demonshire's Central Pyramid, where the battle against the Demon God Bellial took place.

Exclaiming that the future has changed, he talked to himself about how the events that happened at Demonshire had proven the loop's imperfection.

He then ended the conversation, saying that he and Lili "can now be free, even if it's not in the form that they want".

Cryptic Messages in the Murals

Throughout The Knight And KAI's exploration inside the hijacked Heavenhold, they stumble across several murals spread throughout the temples of Heavenhold.

One of them depicts Kaden The Hero, Queen Lili, and the Champion Sword.

Kai attempts to scan the murals in order to piece them together.

The murals changed after Kai scanned them, now putting a corrupted cloud over Kaden, whose figure is replaced by that of the Doctor in the scanned mural.

Not long after KAI's sacrifice, the Doctor appeared in front of his deactivated body.

Demon World Civil War

After greeting the governors of Demon World, the Knight was headed towards the Conference Hall with Lilith and Erina, where they were called by a Saul military soldier, asking the Knight for their time.

Making a remark over The Knight's situation of losing both the Champion's Sword and Heavenhold, the soldier reveals themselves as the Doctor in front of the Knight, startling them.

The Knight tries to fire their arrow at the Doctor, but is unable to harm him in his non-corporeal form.

Warning them of a "flower of death" that's about to blossom in Demon World, the Doctor tells the Knight to look forward to it, before disappearing.

Whilst Morrian fought against her sister Lilith, the Plague Doctor prepared for the Black Flower to bloom, with the flower already planted and growing within the center of the battlefield.

As he makes his way towards the flower, the Doctor gets confronted by Lilith and The Knight, after they both defeated Morrian.

The Doctor told the two that they're not allowed to go further and that they should leave.

Lilith, knowing the true identity of the Doctor, called him out, prompting him to remove his mask, revealing his identity as Kaden the Hero.

Lilith, feeling betrayed and dejected, asked him why he started a war and sacrificed many lives for the flower, to which he explained how he didn't start the war, and that he simply knew it was going to happen.

He continued on, saying that the war is part of history and that it would continue until it consumes half of Demon World's population, before he was told to shut up when he told her that there's no way to prevent it.

Lilith condemned Kaden for not doing anything despite knowing everything about the war, and asked him if he cared about what happens to the Demon World.

Kaden responded, accepting their death if it is needed to stop the impending doom.

As he took his leave and walked away, The Knight attempted to confront him.

Kaden thanked the Knight for taking down Lili, claiming that he wouldn't have made it far had she been around.

He immediately summoned a wall of L-bacteria to block The Knight away, and continued to approach the flower.

As Kaden began to get closer and closer to his destination, The Knight calls him from behind, somehow able to pass through the wall of Labose.

The Knight asks him of his objective, to which he explained that his goal lies behind the flower.

They asked Kaden what would he do if his plan fails, and Kaden, simply laughed it off, thinking it as a dumb question, before telling them that he intend to do his plan over and over until he succeeds.

Sensing that The Knight is about to attack him, he summoned one of his experiments to fight against them, before disappearing into thin air.

Arriving to his destination, he commanded the Black Flower to blossom, proclaiming that he had given up his humanity to open that path.

As he walks near the edge of the cliff, he watched as the flower blooms, invoking Clara's name, telling her that the end is nigh.

Sprouting of the Black Flower

As the flower blooms, numerous rifts began to open, causing monsters to emerge and attack the Demon World.

Kaden approached the pistil of the flower before he was found by an enraged Erina, who sought to kill him for the damages he had done towards Demon World and to Lilith.

The two argued against each other, with Kaden attempting to explain his motives to Erina, saying that the deaths he accumulated over the past 500 years was to find a way to break the loop of destruction, with the plan being to use a crystal comprised of compressed mana that the flower had fed on, and that he'd take on the blame and kill as many people as necessary, if it could save the world.

Erina, seeing how much Kaden has changed over the years and how he's no longer the heroic kid she once knew and how he's no different than the gods that they fought against 500 years ago, decided to try and put an end to his life.

Kaden, feeling disappointed towards Erina's inability to understand, decied to accept her duel and the two fought each other.

As the two continuously hurled attacks at each other, the fight reached a stalemate, with Erina stabbing through Kaden's chest, and Kaden stabbing through hers.

Though, determined to break the loop, Kaden infused the crystal to his heart, restoring his body to full health.

At the same time, he saw Vinette and The Knight approaching the flower.

Without hesitation, he placed a barrier around the flower, exclaiming that he won't allow any more distractions.

As the barrier grew bigger and bigger, he marched towards the flower's center, where a portal towards a different dimension had opened.

He entered the portal, and began searching for the "source of destruction", the will of Labose.

After he found the source of Labose, he merged it with the crystal that he buried in his heart.

Hoping he would learn something that can help him seal Labose, he was instead greeted with emptiness.

Confused, he immediately tried to rationalize why the hivemind was empty, before considering the idea that perhaps the source of destruction wasn't fully Labose, and that the Champion's Sword was also a key factor behind The Loop.

Feeling slightly enraged, he set out to take the sword away from The Knight and destroy it, hoping it would finally break the Loop.

He was finally approached by The Knight, who carried a copy of the Champion's Sword that they found within the Otherworld.

Not wasting any time, he demanded The Knight to hand the sword over, so he could destroy it.

He continued, stating that the sword isn't confined within the loop, thus it didn't need to experience death and rebirth like the rest of the world, and instead is what reinforces it in the first place.

Kaden continued to try and convince them of handing the sword over, exclaiming that every soul would be set free and no longer tied back to The Loop.

Though, he told The Knight that there's a catch in destroying the sword; anyone that is synchronized with it would perish alongside the sword.

Despite such outcome, he told The Knight that sacrificing both them and the Princess's lives is a price worth paying.

A Hero's Sacrifice

The Knight, thinking hard over the decision of whether to give the sword or not, ultimately decided to hand it over to Kaden.

Kaden thanked them for understanding, and without hesitation, destroyed the sword, causing the death of The Knight, the erasure of the fairies and the destruction of The Loop.

The Princess, however, not knowing what had happened and only sensing the death of The Knight, reversed their death, exclaiming she won't let things end that way, bringing them back to the point of decision.

A Hero's Refusal

The Knight, thinking hard over the decision of whether to give the sword or not, ultimately decided not to hand it over.

Kaden, who had already expected much, still felt disappointed at the Knight.

He put his mask back on, and told the Knight that Labose is destructive, strong and posess absolute dominion, although its hivemind was severely lacking, as its only objective is to survive.

As he slowly grows into a new form, he told The Knight that the repetitive destruction that it brought stems from a different will, that being the will of the Champion's Sword, and that he would confront it with his all and destroy it.

Kaden, now in this new form, fought The Knight using the power of Labose, continously summoning monsters and hurling them with spikes.

Seeing the Knight successfully dodge the attacks, he grew into a second form, still attempting to kill The Knight with everything he has.

Still, The Knight was capable of dodging his attacks, and fought back against him in the second form.
