“	A king never betrays the people who trust him. And... I promised someone very important to become a better person and to cherish the people around me.	„
	~ Arthur to Elijah

“	A low groan was the only sound I heard from Turman before we all fell to the ground. Suddenly, I felt like I was deep underwater. I couldn’t breathe and the surrounding air seemed to want to crush me. What was this? It was terrifying. I’d heard that some elite fighters were able to produce a killing intent that could scare mana beasts away, but what the hell was this? Was there such a thing as a killing intent that could actually kill people?	„
	~ Kagul Rolfe in the presence of Note's killing intent

“	I thought of you as nothing more than a mere wasp I deemed unnecessary to kill. But even the holiest of saints would swat it down, without hesitation, if said wasp so much as dared to sting him.	„
	~ Arthur to Lucas

“	The fact is that you’re a walking collection of statistical improbabilities, You have an innate ability to comprehend the workings of the four main elements, as well as some of their deviating elemental forms, coinciding so neatly with the fact that comprehension of all four elements is necessary to unlock the mysteries of aether, which the very princess of dragons just so happens to have kindly bestowed upon you. Everything about you is an outlier, boy. Even asuras don’t have that much innate talent and luck.	„
	~ Wren to Arthur

“	I tried to crawl away; it was all I could manage. I cared not to save face in front of my soldiers. If I didn’t get out of there, I knew I wouldn’t live to feel ashamed. That was when he landed in front of me. His striking blue eyes, which radiated power, gazed down at me in annoyance. I was the son of Karnal Vale, heir to the House of Vale! Yet in front of this boy, who appeared no older than me, I was nothing—not a warrior, not a leader, not a mage. Nothing.	„
	~ Steffan Vale in the presence of Arthur's Power

Summary

Arthur Leywin is the main protagonist of The Beginning After The End. In his previous life, he was known as King Grey, a ruler who stood at the pinnacle of combat and authority in his world. However, his life was cut short when he was assassinated. Instead of meeting a final end, he was reincarnated into the world of Dicathen as Arthur Leywin, the son of the Leywin family. Determined to live differently from his past life, Arthur embraces this second chance with the goal of experiencing love, friendship, and the warmth of family—things he was deprived of as King Grey. His journey leads him to become a formidable warrior, shaping the fate of Dicathen as he strives to protect those he cherishes.

Standard Equipment:

• Dawn's Ballad: During a visit to the auction house with Sylvie and the Helstea Family, Arthur was given the opportunity to choose any weapon he desired. Unable to find a suitable one, he noticed Sylvie digging through a pile of discarded weapons, where she uncovered an unremarkable black rod. Upon closer inspection, Arthur realized it was a sword but was unable to unsheathe it until he activated his beast will. Dawn's Ballad featured a translucent teal blade, contrasting sharply with its matte-black scabbard and handle. The sword had a sleek, narrow design akin to a rapier but with a double edge, making it effective for both slashing and thrusting. After absorbing Arthur’s blood, the weapon bonded with him, adjusting its balance and grip to fit him perfectly. Later, Arthur discovered that the sword was an experimental creation of the asura Wren Kain IV, who deemed it a failure and discarded it in the Beast Glades. Despite this, the weapon proved to be exceptional in battle. However, during his fight against the retainer Jagrette, its blade dulled, and the tip melted due to Jagrette’s corrosive abilities, disrupting its delicate balance. Arthur continued using the damaged sword until his confrontation with Cadell, where Dawn's Ballad was ultimately shattered by Cadell’s soulfire after Arthur managed to wound the scythe with an Aether-infused slash.

Dawn's Ballad

Intelligence: Extraordinary Genius

He possesses the ingenuity to recreate and modify steam engines for new fuel types, understands the mechanics of firearms and their production, and has reinvented the crucible method while demonstrating considerable expertise in crafting high-quality weapons. It is implied that his knowledge extends far beyond these areas, as he had little else to do in his previous life but learn. However, he is cautious about introducing too many technological advancements that could drastically alter the world. He also independently discovered how to create a mana core and successfully taught Lilia—a girl with only a 1% chance of becoming a mage due to her genetics—how to form one as well. He was able to replicate the first stage of Mirage Walk within a month through mere observation of Kordri, a feat that took Windsom an entire year to master even with specialized guidance. Additionally, his advanced understanding of human anatomy allowed him to refine Mirage Walk further, enabling its use in a standing position—something even Kordri himself could not accomplish. He also possesses knowledge of all martial arts from his previous world, including both traditional and modern styles. He is also highly knowledgeable in the art of war and strategy, having undergone rigorous tutelage under Lady Vera in these disciplines.

He possessed an exceptional fighting sense even during his first serious battle, quickly rising to become the most skilled fighter in his country—a world where strength and combat prowess were essential to achieving success. Despite having a below-average ki center that limited his raw strength and speed, he compensated through sheer skill and adaptability. Arthur's ability to comprehend ki techniques was so advanced that he could learn them simply by studying a picture in a book—an otherwise impossible feat.

Arthur underwent rigorous training under Kordri, a martial artist with centuries of experience, and earned his recognition. His refined combat skills enabled him to withstand four stronger and faster opponents while being restricted from striking back, yet they failed to land any meaningful blows. He also mastered and applied Aikido, referred to as "the art of throws," against Taci, further enhancing his hand-to-hand combat abilities. His swordsmanship improved significantly, and he gained extensive experience in battling multiple opponents simultaneously. By the end of his training, his previous level of skill was akin to a toddler just learning to walk in comparison to his newfound mastery.

Standard Tactics:

Weaknesses: Overexerting his mana core comes with severe consequences, often leading to dangerous backlash. Utilizing abilities like Static Void and Realmheart significantly drains his stamina, while Burst Step puts immense strain on his legs, with the risk of crippling him if overused. The full activation of Unleashed Realmheart is particularly fatal, as prolonged use will inevitably lead to his death, with the exact timeframe depending on the extent of power he draws.

Notable Attacks/Techniques:

Static Void - Arthur may use the aether around him to freeze time for everything by using the Acquire Phase of his dragon will; although, this does not include those who can use aether in the same way. However, because this form of aether usage is not suitable for Arthur, no matter how much he uses it or trains it, using Static Void will not be any easier than it was previously. He can't interact with frozen people or items, and the atomsphere's mana particles are also frozen. Thunderclap Impulse (Spell)- This skill is a lightning affinity mana skill that runs currents through the nerves of its user. Arthur can quicken his reflexes several times over for a short time. Average humans have a reaction speed of about 0.3 seconds, and trained fighters can have it shortened to 0.2 or 0.15 seconds, but using this ability, Arthur can shorten this time to 0.05 seconds. Thunderclap Impulse under the influence of Realmheart Absolute Zero (Spell) - Arthur can freeze anything around him at a given radius by absorbing the particles of water attribute mana into his body. Realmheart - By using the Integrate Phase of his dragon will, Arthur goes into a form resembling the dragon who gave him his beast-will. He grows long white hair, and his eyes turn lavender. In this form, Arthur can see all the mana and aether that surround him. Seeing mana and aether allows for more efficient utilization of his mana. The efficiency initially caused him to believe it to be a "mere power-up." Unleashed Realmheart - In this mode, he still has the physique of Realmheart, but his control over the Spatium aspect of aether is greatly increased, allowing him to use a premature form of Godstep, creating short-distance portals through physical space. In addition, all of his physical attacks and strikes with his sword are lightly imbued with aether, increasing their general striking power, but nothing more. This form was only achieved once by Arthur, and has not been replicated or attempted since. Burst Step (Technique) - After learning the basics of Mirage Walk, The secret mana art of the Thyestes Clan, Arthur combines Mirage Walk with a burst of speed created by artificially activating the muscles needed to take a quick step. This technique results in an almost instant, short-ranged movement that is mostly undetectable. Human bodies cannot handle the burden this technique places on the body resulting in Arthur taking permanent damage to his legs, and overuse will cause his legs to become crippled. Typhon's Howl (Spell) - Arthur condenses air mana in his palms. Releasing the mana generates a blast of wind in the direction in which his palms point. Lightning Surge (Spell) - A Lightning attribute attack Arthur launches as a blue lightning barrage, quick and powerful but was only used once in chapter 138.
