The World's most Overpowered Side-Character

"About what?"

"The things that happened on Atla, you always recall the cruelty you witnessed, but I too saw many atrocities on Arkadia, yet you say they pale in comparison."

"The truth of the matter is, the demon-god on Arkadia was patient she gave everyone time to grow so she could have a good fight, but the demon-god from Atla was not, it took ten years; just think about that for a second...

Ten, from the moment I got there, to the moment I left, there was nothing but war, there were no safe havens, no breaks, just war." Sol began descending, finding Ikaris smiling at him.

"That was a splendid display of power love!" Ikaris met Sol in his descent and grabbed his hands while most of the other gods began gathering. "I foresaw this strength, but it is still unimaginable, from the weak and insecure man you once were, you have become the embodiment of power." She took several steps away from him upon landing, allowing the others to get closer.

Sol stood there smiling, with Zola under the systems hidden command he could utilize the sparse mana in the air, so he had indeed directly gained from killing the seven demon-gods...

Everything seemed fine, but in the back of his head his past after being brought up constantly was eating at him, and the only one who seemed to notice his distress was Ikaris when she felt his mood drop and his tone shift even though his smile only brightened.

"That is enough now, all of you!" She called from the back of the crowd flying over their heads and taking Sol's hand. "I mean to speak with him in private, please return." She looked around, quickly addressing everyone before pulling him through the crowd and into their temporary house.

"Ikaris, what's wrong?" Sol asked her as soon as they were behind the door, when he saw her erect a barrier and block out all interference.

"I should ask you that question." She turned to him and closed the space between them. "Your mind is not here, love, you feel worlds away even though you are right before me, this happened a lot on Arkadia too, where do you go that causes your soul to flicker?"

"Atla." Sol took a seat in front of the turned off TV and closed his eyes when she sat next to him and pulled him into a hug, lying down and cradling his head against her breasts. "Every time I get the luxury of peace, my mind always wanders back home."

"Home?" Ikaris stopped caressing his cheek.

"I spent ten years there, it is your home, where you belong, it's also home for me." He answered, and she felt her lips curl without her consent into a small smile.

"I see." She watched him quickly drift off into sleep.

***Ten years ago***

Malnourished and hopelessly depressed, Sol stared at himself lying on the floor and frothing at the mouth with ramen sticking through his mouth and nose, after one bad slurp everything happened so fast that he had gone into shock and died without much of a struggle.

For a single moment of clarity after his tragic death Sol stood and stared at himself as an astral projection, seeing the events of his life like a montage.

"So, I'm dying?" He tried kicking himself but his foot simply passed through the body. "No... I am dead." He tried kicking himself again. "Well shit, what now, heaven, hell, limbo?" He asked taking a step toward the door of his run-down apartment. "Will I just haunt and exist here forever?"

Before he reached the door, he felt a tug, an irresistible tug against him, and without the ability to react he was whisked across the room and then dragged through the roof by an unseen force. It was supposed to be terrifying, but he couldn't express fear in this state he just accepted whatever was happening as beyond his control.

Beyond his building, above the city, beyond his country and continent he kept being dragged until he was outside of the planet entirely, and he found himself mesmerised at the sight of hundreds of thousands of others like himself who had been dragged off earth, they all witnessed each other but they couldn't communicate, as if they existed and didn't at the same time they couldn't touch each other.

"This is-" Sol opened his mouth to speak, but felt heat at the tips of his fingers, and upon looking down he found a tube beneath him, a swirling tube that extended from the core of the earth and held on to him.

"I'm damned." He stared at the core through the crust, and the shape of a humanoid creature which stood inside of it, it had seven levels and seven heads and each part of its body seemed to function in a different way, he couldn't see them, but he could already hear the screams of the dead. "Is that, hell?"

Nobody was there to answer his question, and only a few seconds after he and the other dead had been dragged from the world of the living he witnessed everyone around him getting sucked through those strange tubes, their bodies started deteriorating and their souls became physical anomalies that began undergoing rapid deconstruction and reconstruction as their bodies and everything inside of them caught aflame at the pace of a breathing child exuding and absorbing crimson flames.

"Wait!" Reality suddenly hit him when his hand caught aflame as well, a fire so rough and violent it caused his skin and bones to melt and peel off, reforming and repeating the process as he started slowly sinking into the tube, but then he stopped.

Another force started pulling him, and above his head a bright white portal appeared, tearing off and releasing his arm into the tube and then dragging him away and closing just before several other creatures appeared in an attempt to seize him.

This new light caused warmth he had never felt before, and after a few seconds of basking in that warmth and the softness that accompanied it beneath his head Sol felt a hand tapping his chest.

"Are you able to speak?" A sweet voice called to him, and he quickly opened his eyes, immediately making four with pair of beautiful blue eyes with pupils that sparkled with what seemed like galaxies.

"Is this... Heaven?" Sol asked, and received a small chuckle as she helped him sit up from her lap and then stood before him. "What's going on, didn't I die?"

"I am grateful for your presence, Sol," she took his hands and helped him to his feet. "I need your help."

"You're beautiful."

"Focus."

"S-sorry," Sol averted his eyes when they started scanning the woman before him. "What's going on, where is this?"

"First, an introduction." She disappeared from before him, reappearing several feet away and taking a seat and crossing her legs as a small throne appeared and cradled her rear.

"You asked if you were in heaven, the answer in a sense should be yes, but this is just a temporary visit, Sol Vestic, you died on earth-"

"So everything I saw was real..." He looked down, and sure enough his left arm was missing from the elbow down. "... That was hell."

"I am Ikaris, Goddess of this universe." She stared at him with a passive smile after he nonchalantly interrupted her.

"You're god?" Sol stared at her with his mouth agape, and the goddess chuckled again and shook her head.

"Not the one you are expecting, after your death, I saved your soul from damnation, in a sense I stole you from your home dimension." Ikaris responded.

"Because..." Sol looked at himself and then at the vast white space where she had taken him. "You need my help?" He asked, and she nodded. "Isekai." Sol stared at his hand and his eyes sparkled as the thought of another world intruded his stupor.

"What is isekai?" Ikaris raised a brow.

"Ah, nothing important, is there some kind of dragon or something I have to slay after becoming an adventurer-"

"I admire your excitement and acceptance, Sol, but please listen carefully." She sat forward and stared at him seriously, erasing his excitement and somehow exuding even more attraction with her lack of humour, once again, Sol's eyes locked onto her.

"Okay."

"Summoning you here from your home-dimension has caused a strain on me that I did not expect, but upon sensing your soul across dimensions in the first place I had to, you are the only one who can help me here, Sol." She locked her fingers as several images appeared in his vision.

"Atla is about to fall in a state of depravity and desolation, a demonic army appeared sometime ago, and it was being handled, but in the last few years my people have been at their mercy, I am unable to help, and my people lack the power to win this war, I need your strength-"

"I'm a weakling, though." Sol countered.

"Right now you are, but the reason I risked everything to bring you here is because I sense greatness within you the likes of which no other being possesses." Ikaris rested her cheek in her palm and stopped the images from circulating in his mind.

"I will not throw you into a pit without tools, whatever it is that you need, I will grant it to you, and should you ever require help, I will grant you more power-"

"Power?"

"Magic."

"Real magic?"

"Yes, real magic, I have already granted my blessing to you, when you are sent to Atla, you will be able to use magic like everyone else, and overtime that power grows."

"Do I get to choose what kind?" Sol asked seriously, and the goddess raised her head and smiled.

"I thought about that beforehand, so I granted you the ability of creation which ties to your mind, as long as you can grasp it, any magic feasible can be controlled by you."

"That's... Overpowered."

"It befits one of your calibre." Ikaris nodded. "If that is all, then I will send you to Atla now, unfortunately I cannot always converse, but if the situation demands it I will enlighten you at your becon, my hero."

"W-wait, I don't want to fight a fucking demon army!" Sol snapped, but by the time he was halfway through speaking he was enveloped by golden light and sent falling through the ground beneath him.

On that day Atla became alive with majicul (their name for mana), it was visible to the naked eye, and the skies all cried with the voices of angels as the armies on both sides watched the clouds open up and a beam of gold crash to the surface leaving a giant crater and wiping out an entire horde of demons.

"Do your best, Sol, I will watch over your shoulders."
