100 years ago, there was a large-scale natural disaster known as Gnevva, this disaster wiped out 80% of the world's human population and caused the decline of the times.
Two minutes before the disaster occurred, people in the western hemisphere saw a very bright object in the night sky, the mysterious object was hurtling and crashed into the ocean.
The impact of the mysterious object caused a series of terrible natural disasters, ranging from tsunamis, earthquakes, violent storms and volcanic eruptions. In addition, the explosive effect of the impact spread radiation and various types of dangerous viruses to all corners of the world.
Gnevva makes mankind suffer greatly, all the water in the world is polluted by deadly radiation, mankind must wait for rain to fall if it wants to drink safe water. Likewise with food, mankind eats radiation-resistant plants or eats fellow humans.
The Gnevva disaster lasted for 5 years. A knight appeared in the night and stopped the great calamity, he repaired the damage in the world using black magic. The mysterious figure is known as the Dark Knight. Humans who survived the Gnevva disaster built a new civilization and made the Dark Knights heroes. However, humanity does not know the true identity of the Dark Knight.
75 years after the Gnevva disaster, an investigative team formed by the World Kingdoms Union or W.K.U managed to find the coordinates of the mysterious object's fall. The team of 20 people was dispatched to the waters of Aska and they found a colossal sized tower.
The investigation team concluded that the massive tower came from outer space, then fell into the world and caused the Gnevva disaster.
Initially, the large tower was given the name Gargantuar by W.K.U, but changed its name to Reliquia since W.K.U disbanded and the Skyscraper officially took control of the tower.

“My students, from the brief history described earlier, is there anything you would like to ask?” A bearded old man, who works as a history teacher, is educating the childrens in an open room.
“Teacher, black magic isn't good, but how did it stop the Gnevva disaster?” Asked a female student with short black hair, she raised her right hand as high as possible, then smiled sweetly.
"Oh, sorry, I don't know. Your question can only be answered by someone skilled in magic,” replied the teacher.
"Too bad....” The female student who asked earlier lowered her right hand onto the wooden table. Even though she didn't get an answer, she not feel disappointed at all, because she just wanted to look active in the eyes of her teacher and friends.
The teacher cleared his throat, "All right, kids, it's 2 in the afternoon, you can leave the class now."
“HORAYY!!!” The students in the room cheered in unison, they looked happy when class was over.
“....” Except for the black-haired boy who was sitting in the back row, he didn't join in the cheers, instead he put on a straight face and glanced at the window. The quiet boy watched the tower of Reliquia, while propping his chin.
"Yo, Satrio, ahak-ahak, let's go to the playground, yo!" A boy took the quiet child, while dancing.
"Don't daydream, Tio. Let's go to the playground." A girl massaged the quiet boy's shoulder gently.
"S-Satrio, let's play in the playground." A shy girl fiddled with her fingers as she said that.
The calm boy named Satrio sighed, then he stood up from the wooden chair, then said in a languid voice, "Okay, let's go to the playground."
“Gasss!” exclaimed the boy who loved to dance.
"Well, that's it," said the girl who was massaging Satrio's shoulders.
“U-Understood,” said the shy girl, nodding slightly.
The four students went to the playground, they walked together on the green grass and talked about boredom when they were in class.
....
15:10 P.M
The children were having fun in the playground, suddenly a group of bad boys came over and rioted there, they pranked the girls and beat the boys with iron sticks.
Satrio does not accept that his friends are being bullied by bad boys, he challenges those who make trouble in the playground.
“This playground is not a place to fight, come with me, I will beat you all in a quiet place,” said Satrio, he walked leisurely towards the garden gate.
“Hah? That kid is really suck, let’s beat him up later,” said a bad boy holding an iron stick.
“We’ll give you a big lesson, hahaha.” Thebad boy who was wearing a dull jacket laughed out loud.
....
15:45 P.M
After a long journey, Satrio and the bad childrens were in a place with lots of trees. The location was very quiet, Satrio only heard the melodious whistling sound of the wind there.
While warming up to beat the bad childrens, Satrio felt something in the house near the location, he saw the house emitting an aura of emptiness that was very-very destructive.
A terrifying void aura. Unexpectedly, thanks to serving these bad boys, I accidentally found her hiding place. Damn, that woman hid it well, she was also able to minimize her presence. Satrio thought, snapping his fingers and putting on his best stance.
“Wow, you chose an amazing place to fight, your taste is good,” said bad boy A.
“Thank you for praising me,” replied Satrio.
“Ha ha ha ha. Don’t be proud just yet, this place will be your grave, you little beast!” mocked bad boy B.
“I don’t feel proud at all. I won’t boast about something from trash like you guys,” replied Satrio.
“Bastard! You bastard!” cried bad boy C, his brow furrowed in annoyance.
“Don’t talk too much! Let’s destroy this stupid kid flat face!” cried the bad boy D, lifting the iron rod over his right shoulder.
I really want to kill these childrens, their mouths are too sharp, but I must calm down and obey the laws that apply in this land. I can’t be careless. Satriothought.
“One, two, three. ATTACK!!!” shouted bad boy A, he started the opening attack with a kick. However, Satrio managed to dodge bad boy A kick and launched a counterattack, he slammed the boy to the ground, then beat him hard.
A few seconds later, bad boy A friends came to help, they stormed Satrio at the same time.
