Achilles. A great hero who rivaled the legendary Greek hero Heracles in terms of fame. There were probably less than ten heroes, including him, whose names were known on a global scale. However, the number of people decreased when it came to those who knew the story of the rushed and short life of this great sprinter.
Born from the sea goddess Thetis and the hero Peleus, Achilles was blessed by the gods from birth. His mother Thetis, having greatly loved her son, had warmed him within holy flames in order to try and make him immortal. But her husband Peleus had opposed it, saying "Then that would destroy Achilles as a human", and in the end Achilles grew up while only a certain part of himremained human.
Eventually, when war broke out between Troia and Achaea, Achilles was asked the following by his mother Thetis.
—Do you wish to live a long and peaceful life without having your name recognized by the masses? Or do you wish to live the short life of a hero with brilliant achievements in battle?
Achilles' choice went without saying. At the same time as his mother felt pride in his decision, she also felt heartbreakingly sad. Because his fate had been predetermined since he was born. If he lived as a hero, he would have a short life, as if sprinting through it at full speed.
After having grown up, he participated in the Trojan War as part of the Achaean army and continued achieving many great feats. His body, blessed by all the gods, never received any wounds, and the spear that his father had given to him pierced through all other heroes. With his chariot led by three steeds, consisting of two divine horses given to him as a gift from the sea god and a famous horse he stole while assaulting a certain city, no one could chase after him from behind.
But during the one-on-one fight between Achilles and the greatest hero in the Trojan War, Hector, who was equal in strength and skill with Achilles, his weak point was exposed. Even if Hector was the killer of Achilles' close friend Patroclus, the way Achilles insulted him by dragging his corpse around with his chariot was a foolish and intolerable act.
As a result, he incurred the displeasure of the sun god Apollo, but despite being repeatedly warned to restrain himself, Achilles continued slaughtering the Trojan army. So the enraged Apollo aided the Trojan army's bow expert Paris, and guided him to shoot Achilles' only weak point—that is, his heel.
Having his heart pierced by arrows one after another afterwards, Achilles sensed his own death, but continued fiercely fighting and using all his strength to kill the soldiers of the Trojan army around him. Just as predicted, he had a short life, but his legend as a hero was carved into the world.
A human who was exceedingly close to the level of the gods, a fast-sprinting hero with an invincible body. But his heel alone—was this hero's vital weak point.
And Archer of Black, Chiron, served as Achilles' teacher. When Achilles was a young child, his mother Thetis returned to her home at the bottom of the sea due to discord with his father Peleus. Chiron, who had raised many heroes, was an old friend of Peleus, and happily accepted the role of training Achilles.
...Yes. It was only natural that Achilles had wavered for an instant. Chiron had been an absolute figure and symbol to his younger self. His gentleness, seriousness and words had been engraved like magic into the young Achilles.
For nine years—Chiron was a father, teacher, older brother and close friend whom he spent his childhood with, when he was at his most sensitive. For Achilles, who was the son of a hero, had received the blessings of the Olympian gods and had been given looks of awe, respect and admiration from many young warriors, there were few people he could truly call his friends or teachers.
