This backstory is based on the CW Film, The Flash. If you guys had watched it, the backstory is mostly the same. So just like the Heroic Tale that we already knew about at the Danmachi series. Like Argonaut and the Knights of Fianna.

Argonaut reincarnated as Bell.

Fianna reincarnated as Lili.

Dim reincarnated as Finn.

This is the Heroic Tale of Sora's favorite tale, The Flash.

A/N: Albeit, this is also one of my favorite movie. All from season 1–9 was spectacular and fantastic.

(BackStory)

The event takes place 5 years after Argonaut, but 5 years before Knights of Fianna. And the Flash is known as the second Hero that has ever appeared in History.

Zora(Sora's reincarnation).

And just like in the movie. Zora was 11 years old when his mother was killed in a bizarre and terrifying incident. He saw Blue and Purple Lightning in his house. And his father was falsely convicted of the murder and was sentenced to death. With his life changed forever by the tragedy, Zora was taken in and raised by his Foster father, and his best friend, Stacia. Despite being human, Stacia was well versed in Healing Magic. And she's good at wielding a sword. Even more so than Zora.

Stacia(Asuna's reincarnation). She's human during that time. Not High Elf.

And just like Argonaut, Zora was also dubbed as a Fool. When nobody other than Stacia believed a word he said when he saw the strange thunderstorm that had happened that night during his Mother's death. So when he grew older, Zora was determined to find out the source of that Strange Bizarre incident that happened that night. And both he and Stacia set out on a journey. But another incident happen before they could start their journey.

(Struck by Lightning)

During the day of the Departure, a rainstorm of clouds are formed and they had to postponed the trip. But just as they were taking shelters at their own home, a Huge Bolt of Lightning struck down the window where Zora was leaning on and struck him down making him in a coma for over 9 months.

Yes, I decided the Blue Lightning in Ezra Miller's Flash. Not Grant Gustin Orange Lightning. So it contradicts with Sora's lightning.

After recovering from his coma thanks to Stacia's healing Magic, they set out on their journey to find answers. During the journey, Zora realized that the accident has given him the power of super speed, granting him the ability to move through places like an unseen guardian angel. Though initially excited by his newfound powers, Zora is shocked to discover that the Blue Lightning that emits from his body was the same one that he saw during the incident.

(Friends)

During the journey towards Lakrious where they heard a strange rumor where purple lightning had been sights. To find answers, both him and Stacia got ambushed by a Monster Party where the two of them were surrounded from all sight. Due to him always relying on his newfound strength. He didn't realized that when he ran too much, causes his Glucose levels to drop, making him easily pass out. Without his speed, he's defenseless. It was then when they were rescued by a girl whom eyes were glowing.

Korra Azumi(Rin's reincarnation)

There she introduced herself as Korra Azumi, who at that time was a newly Knight at the Kingdom of Lakrious. It turns out, she was gifted with Magic of all 5 Elements (Wind, Water, Earth, Fire, and Lightning) which surprises both Zora and Stacia. She explain to them that she had made a Contract with a Spirit whom appeared out of thin air and introduced herself as Reno.

Reno, Korra's contracted Spirit.

She led both Zora and Stacia to the Kingdom of Lakrious where Zora and Stacia met up Korra's best friend who was an elf named Myura.

Myura(Muller's reincarnation)

She too was a newly appointed Knight of Lakrious. There Zora and Stacia make a presences with Lakrious Princess where those two met up with a blonde princess Ariadne and her adopted little sister named Feena a half elf.

Ariadne(Aiz's reincarnation)

Feena(Lefiya's reincarnation)

There, Zora tells them the whole story of his childhood, where his Mother was murdered. Hearing that his Mother had died, both Ariadne and Feena fell into tears surprising both Zora and Stacia. It was then they were told that the Clown, known as Argonaut just died recently as well.

Those tears made Zora and Stacia bewildered. They had of course heard of Argonaut's heroic tale from the Wishe Poet Ryulu and the Fortune Teller, Orna.

Ryulu(Ryuu's reincarnation)

After apologizing for the sudden change, Zora continues on, asking about whether or not the Princess Aridne or Feena had known anything regarding the man in purple lightning, or anything related to that. It turns out, strange purple lightning had been sight almost all over the Kingdom of Lakrious. And monsters, mostly dragons was in sight every time a purple lightning would appear.

Thanking for the information, Zora and Stacia were granted permission to live at Lakrious. Where those two befriended, an Amazon named Elmina, a Dwarf named Galmus, and a werewolf named Yuri.

Elmina(Tione's reincarnation)

Galmus(Gareth's reincarnation)

Yuri(Bete's reincarnation)

(Villain)

During their stays at Lakrious, just like Ariadne and Feena had told them. Multiple purple lightning was sight there. Or to be more exacts, a purple thunderstorm at the sky. Seeing this reminded both Zora and Stacia about the Blue Lightning Thunderstorm that happened at their village. Then it turns out, their assumption was right on spot. Zora indeed saw a person clad in purple lightning.

Pu(PoH's reincarnation)

Zora and Stacia both confronted the man. Whom turns out to be a wanted man that was known as a true serial killer. Whom is ecstatic to see people at their dying moments. Zora confronted him about the incident that occurred when he was a Child, but the man had no idea what Zora was on about. In their face off, both Zora and Stacia were defeated by Pu. It turns out, just like how Zora was struck by lightning, the man named Pu was also struck by the Purple Lightning in the sky. Though they were ultimately saved by, Korra, and Myura, the man manages to escaped.

(Crisis)

The Dragon that was in sighting turns out was drawn by the person the purple lightning magical power. A swarm of dragon appeared at the Kingdom of Lakrious, and at the center was a Crimson Red Dragon, with a certain villain riding on it.

Confronting the man, Zora, Stacia, Korra, Myura, Feena, Ariadne, Ryulu, Galmus, and Yuri all fight against the hordes of Dragons. The Flash fought his nemesis, the Reverse-Flash, with the help of his allies in an extreme battle in Lakrious. Facing off with the Red Dragon and Pu, was Zora whom had been taught on how to control his lightning by the Great Spirit Reno herself. The fight ended with both speedsters disappearing in an explosion of light.

(Post Crisis)

After the explosion of Light, Zora was awoken at a certain familiar place. He wander around and he realized that it was indeed his home. But what surprises him the most was when he saw his parents and his younger self there. It was then Zora realized that he was indeed back in the past, specifically the day that his mother, was brutally murdered. Soon after spending some time with Mother and Father (he didn't reveal who he really was), Zora ran into Pu whom also turned out to be brought back into the past. While Zora was initially unsure about why his adversary was there, their conversation made him realize this was the younger version of Pu. The Pu who didn't known about the events that happened here, the person whom come back to kill Zora as a child.

Zora: Ever since my parent passed, I never stop wondering... Where I would give, to have them back for just one more day? If that happened, what I would say.

Mother: You can tell us.

Zora: I'd say, 'Your love made me who I am. And despite the darkness, you still carry your light inside me every single day.'

Mother: I know your parents would've love that, Sora(The named that Zora introduced himself when they meet one another).

Father: And have no doubt, whoever they are, they're proud of you, son.

With this, Zora finally gets the closure he was looking for ever since. After bidding goodbye to his parents, Zora ran after Pu and attempted to persuade him not to go through with his plan. As Zora knows, the purple-garbed speedster may win this "battle," but in the end, he'll never the "war" between them. But Pu refused to listen to him, so Zora had no other choice but to now play his role in events that, from his perspective, happened long ago.

Future Zora became the Lightning in blue and fought against Pu Reverse-Flash whom had purple lightning, and saving his 10-year-old self from his arch-nemesis. In order for the timeline not to be disrupted. Knowing how things played out before, as well as remembering his closure during his final moment with his parents was, he knows that as tragic as this is, His Mother needs to die.

After rushing his adolescent self to safety, Future Zora caught up with Pu, who'd now lost his speed after killing Zora's Mother. While Pu vowed revenge against Zora for leaving him stuck at the past, Zora already knows how the rest of Pu's story goes. So instead, he thanked his adversary for helping him get closure and peace for this traumatic night. Our main protagonist then disappeared again in a flash of blue light, leaving Pu to scream in rage.

A/N: Well, this is just my own version that happened. If you guys want to know more, just watch the movie on Netflix. This story later on will be used on the (Xenos Arc) on my Danmachi Sword Oratoria.
