Reincarnation: From Commonplace to the King of Heroes

Summoning of Heroes

One day after the party.......
Gilgamesh was training with his bow, when suddenly a bright pillar of lift appeared, and an explosion right after.
Gil thought -"looks like the heroes are summoned already, let's check it out"

Gil slides towards the castle using demon's extract as fast as he possibly could go
When he opened the door, he was shocked, his old classmates were there. He remembered them all.
Shirou, his best buddy
Ken, the bully
Akari, the girl he used to have a crush on
Ren, the super emo kid in class that nobody talks to
And so on
The summoned heroes are currently getting their statuses checked

First up was Ken, he was a demonic swordsman, his physical ability is at genius level, but his magic ability is only average. He has a strong dark affinity, and a talent for awrdsmanahip

Second was Ren, his class is assassin, his agility and physical power is at genius level, and his magic power was above average as well, his magic ability: flash boost, allows him to triple his already monstrous speed for 5 minutes. He has affinity for ghost fire and wind magic, and he has talent for dual dagger arts

Third was Shirou, his class is Jack of All Trades, it means he has access to abilities of all classes, and his stats are all above average as well, he doesn't have affinity for regular magic, but has an affinity to null magic
,he currently only has one skill: power boost, which could boost the user's physical power for a period of time, overusing could result in muscle damage. But to make up for his lack of magic, he has talent for all weapons

King-"ah, Gilgamesh, you came just in time. I was just about to send someone to look for you."

Weeb student-"G-G-GILGAMESH?!"

Gilgamesh-"oh? What does this have to do with me?"

Weeb student-"blond hair....red eyes.....that attitude.....HES GILGAMESH FROM THE FATE SERIES!!"
Other students who knew the fate series were shocked at this revelation
King-"well, since you are the strongest teen in this kingdom, I figured you could train them."

Gil-"why?"
King-"hm?"
Gil-"why do I have to help these mongrels?"

Ken-"what? You think we aren't good enough for you, huh?!"
Gil-"exactly, now shut your filthy mouth, rabid dog"
Ken-"what did you say?!"
Gil was just about to skewer that son of a bitch with swords, but.....
Shirou-"guys, guys! Chill out! I'm sure we can figure out a solution to this problem."

He turns to Gil
"How about this, if we beat you in a mock battle, you would have to train us. And if you win, you don't have to."

Gil-"I will only train those who beat me, dont worry I will only go 20%, is that good enough, mongrels?"
Gil took out Grand Chariot from the gate

The class decided to go at him together, they figured quantity>quality
Gil-"oh? So you decided to come at me altogether huh?"

Ken-"get ready to die, you brat!"

Gil-"heh, then here I come. Trace, on!"
kanshou and byakuya appeared in his hands

Ken-"n-Nani- UUURRAAAHHH"
Before Ken could even react, he was kicked in the face
Gil-"So......whose next?"

The rest of the class except Shirou and Ren rushed at Gil
He knocked them out one by one
"Is that all you have? I could hardly call you bunch heroes"
He kicked a girl to the wall
"I don't see why the kingdom needs trash like you"

All that's left of the class are Ren and Shirou
"So, are you two going to come at me or not?"

Ren-"Hmph, I can beat you alone"
He disappeared from his spot and is now right beside Gilgamesh
Gil-"what the-"
He was sent crashing to the wall

Gil thought-"ah, I forgot Ren was a martial arts champion"
He gets up, and wipes off the dust on his face
"Not bad, not bad at all"

The temperature in the area drops to almost zero, ice starts appearing in Gil's arms, forming spiked arm guards

Ren and Gil starts to clash
Ren-"you are not bad yourself, king of heroes"

Gil-"Hmph, dont laugh too soon"
Gil speeds up and kicks Ren to the ground
"You pass"
He turns to Shirou

"Are you going to come, or am I going to come to you?"
Gil grabs a regular sword from the gate of Babylon and tosses it to Shirou

As soon as Shirou touched the sword, he instantly knew how to use it
"Get ready, Gilgamesh, it won't be that easy to beat me"

Gil-"oooooh! You suddenly got an attitude huh?"
Shirou-"power........boost!"

Gil-"power wha- OOOOOOOOOF"
Gil got uppercutted in the face and was sent flying

Shirou-"TAKE THIS!!!!"
Shirou launches a barrage of pure mana blasts at Gil,

don't even question how he learned it, remember, he has talent in every weapon, your body could be a weapon if you train it

Gil emerged from the smoke almost unscathed
"I'm sorry, power what?"

Shirou-"power crap"

Gil-"thought so"
He round-house kicked him into the wall
"You passed as well, meet me on the training ground tomorrow. As for the rest of you......you are not even worth training, go die for all I care"
