Elemental Hero in Teyvat

As soon Sekai gets up from the ground after a minute of complaining he check himself on what he got from ROB beside his current outfits he looks on his right hand and there a watch, not just any kind of watch but a watch that give its owner an ability to control elemental energy. Yeah, it was that watch from Boboiboy cartoon.

He inspects the watch, and find out that instead of capital B on the watch, it changes to S, and the other element except light is grey in color. He suddenly gets a feeling of dread. He tried to change to fire element but the watch didn't give him any response.

Sekai: Yeah… I'm afraid it was as I guess; I can only currently used light element. I guess this isn't so bad at least it not the worse where I can't event used it. I meant, let just test the light element.

Sekai: Sekai Light Power!!

Bright light engulfed Sekai, and his cloth change into white color, his glove turns grey with a line of yellow.

Sekai: Light Speed

Sekai moves swiftly to front while dodging tree in front of him, but suddenly wild boar rush from his right blasting him towards another tree.

Sekai: Gah!!... you… just make a big mistake!!

Sekai glare at the wild boar making it shudder, the boar feeling threaten start to run away

Sekai: Why are you running?... Where are you running?

Sekai chases the wild board in his rage, while the boar keeps on running for its life.

Sekai: Come out, come out where ever you are…

Suddenly Sekai heard people's screaming nearby as he quickly changes his priority to the sources of voices.

Sekai: This is your lucky day boar, next time… I will fry you!! Light Speed!

He rushes towards the voice and upon his arrival he sees civilians running away and heading towards the opposite direction as he suddenly got bumped by one of the people

Sekai: H-Hey!?

Civilian: Run! There huge waves of monsters heading to this way!!

Sekai: NANI!?

As the man runs off leaving Sekai behind as he turned his attention on opposite direction, his eyes suddenly widened in shock when he sees humanoid like creature with claws and huge mask along some beast-like creature following them as well.

Sekai was shocked and a bit scared as well, but then he heard a woman crying for help as he seen a mother and daughter currently hugging each other and cowering in fear as some of the monster a rushing towards them

Woman: Please! Someone! Help!

She pleaded once more as one of the creatures raised it weapon and about to struck them down

Sekai: Light Speed! Light Cut!

Suddenly fast yellowish blur appeared in front of them as quickly killed the beast and the rest as the mother and daughter looked at their savior.

A young man with average build and appears to be in his late teens, he has a black hair and sharp blue eyes, he wears a grey dress shirt with a grey waist-coat and white trousers. He also wears white laced shoes. He also wears a grey glove with an orange color watch on his right hand.

Over his shirt, he has a white trench coat with silver hood. His coat has a Solar logo (the logo will change according to what element Sekai used) on the back. It was Sekai.

As he turned towards the family and walks towards as he smiles at them

Sekai: You two alright?

The mother and daughter nods at him as he walked away from them

Sekai: Go, I'll handle this

He said with Archer smile.

Woman: T-thank you!

The woman said with a slight blush as he picks her daughter and run leaving him again to face the incoming swarm of monster. Sekai turned his attention towards the creatures.

Sekai: So… it's just us now huh? Alright then.

He said as the monster rush at him as he slowly points his hand making it into pistol like gesture.

Sekai: Kakatte Koi!! Light Beam!

The light beam shot instantly reach one of the monsters and continue to penetrate its body and reach the beast behind it. Seeing their companion fall from the attacks, the monster rage and charge at him but Sekai quickly dodge using light speed and he begin spamming light beam with super precis accuracy.

One giant beast come out of nowhere and tried to mauled him but Sekai managed to avoid it by back flipping into the mid-air.

As he was close at the beast face, he kicks it making it call into the ground as he landed on roll as more of the monster coming towards him as he began shooting them of with light beam.

Then he used Light Burst to temporally blind the beast and begun spamming light beam again at the monster making them fall with every shoot while he keeps on light speed zig zaging towards to the rest of the monster, but then one monster charge at him then Sekai opens his palm pushing towards the beast

Sekai: Light Force!

He roars and push back the monster sending the beast crashing into the hoard of monster, killing it alongside the crash.

Then another batch of monsters jumps on him, But Sekai manages to shoot them down when he turned around and perform a spinning kick at several monster that to near to him. Another wave was coming at him fast then he joints both of his palm making into pistol-like figure

Sekai: Optical Light Shoot!!

The big light beam engulfed the monster wave leaving only destruction on it way. Sekai looks at destruction that he made…

Sekai: Huh… Just hope there is no extreme conservationist in this world or I need to pay for that… yeah just act as its was monster fault… yeah

Then Sekai sweat drop as he turned towards the enemies and rushes at them using Light Speed while he doge incoming arrow and claw from another monster as he used light beam once more and shoot them down one by one.

He rushes at them with the speed of light (I mean using light speed is equally as he is as fast as light) as he keeps on gunning the monster left and right while sometime using light burst to immobilize the crowd.

He continues to fight combining Light Speed, Light Beam and Light Force making it more effective against them as he begins shooting them one after another.

Sekai: Time to end this! Maximum Optical Light Blast!!

Suddenly Sekai starts to accumulate light elemental energy in front of him as the remaining creature is now cowering in fear as he starts to accumulate more and more light elemental energy.

Sekai: Bang…

A huge beam of light head straight towards the remaining monster that didn't manage to flee, consuming them into ashes.

As soon as the light faded away, Sekai walks towards now destroyed area as he sees a surviving monster staring at him. Then he used light speed to instantly move in front the beast and aimed his finger on its head.

Sekai: Bullseyes.

He said as he did a pull trigger action causing light beam to shoot directly to beast head making it exploded on front of him.

…

As he sighs in relief, he walked away a few moments later. Sekai come out from the cliff as the survivors were shocked that he was alive and he also defeated all the monsters that chasing them

Sekai: It's alright everyone, there no need to be afraid anymore. They're gone.

Civilian: T-Thank you, mister

Sekai: Its fine, I should get going now

He said hurriedly as he didn't want to be accountable for the destruction that he made.

It's been a few hours again and its almost sunset and Sekai was still walking while feeling very hungry. He sees one of the world deity statues. He touches the statue and feel like something inside him awaken.

Sekai: That feel like something… but… damn what I need right now is food… so hungry…

He said while holding his growling stomach as he suddenly falls to ground beside the statue while looking at biggest tree, he sees for both of his life. He can feel his eyes were closing due to exhaustion. He didn't notice that his watch starts to shine in green color while he is being surround by Anemo elemental energy.

From afar, there two figures running towards Sekai direction.
