The World's most Overpowered Side-Character

The camp went quiet when the object was revealed, it created a light that cast shadows on even the fires as it stole the attention of every living being.

All eyes focosed on them.

"What is this?" Ikaris asked behind her fingers and Sol closed his eyes and opened them again. "Sol?" She questioned him again, watching him swallow his fears and smile at her with his eyes puffy and his hands slightly shaking.

"Originally..." Sol started. "I was going to ask you the next time we left, but I couldn't find a more beautiful moment than now, Ikaris, you have truly made me the happiest man in every way I can think of..." He slightly raised his hand, revealing the curved silver ring with a centrepiece that glowed and shimmered in different colours like a distant star. "Please, marry me..."

"Sol..." Ikaris stared at him too shocked to speak, and then looked at Dina and Arla who were tearing up alongside Eris and even Usami.

"I..." She sucked in a breath and took a step toward him, extending her left hand as she had seen many mortals do so many times in the past.

"It would be the greatest honour, if you would make me your bride." She started crying as she raised her hand to him, and with an expression of nigh disbelief, Sol slowly slid the ring onto her finger and then looked at her again, but before he could utter a word Ikaris tackled him to the ground and started showering him with kisses, while the camp erupted in cheer and celebration.

"This is so bittersweet," Arla commented, placing her hand over her heart and sighing.

But she did so secretly letting nobody hear her words.

"Such an... Auspicious occasion."

The camp fell silent again, and everyone looked to the skies as a large demonic gate opened up and a figure slowly descended through it.

The mood fell and the regular soldiers felt foreboding danger, while the captains and heroes drew and summoned their respective weapons.

"I hope my presence does not dampen the... Celebration, I simply came to bid you, congratulations... Goddess of battle; Ikaris, and to meet your husband-to-be, Sol Vestic." The being spoke again.

"What the hell!?" Dina raised her hands while Usami arched to throw her spear-

"Nobody move!" Sol's voice roared and echoed across the entire army as he held on to Ikaris and hid her behind himself with his teeth baring against the intruder as sweat trickled down his cheek, Ikaris too was in a dilemma, if she was attacked, there was a very real chance of her dying which was why Sol had shielded her with his body.

"What the hell are you actually doing here?" Sol asked, staring up at the female clad in armour as she slowly descended and landed before him and Ikaris with her hands folded and a thin tail flicking behind her.

"I have been watching you all, Sol Vestic, Ikaris, Han Young, Dina Levina, Usami Takae, Bruce Chaolong and Eris Schneider..." She looked over Sol's shoulder at the other heroes, and they all felt their mana vibrate at just the sight of her.

"Answer me!" Sol summoned a sword in his grasp, but Ikaris grabbed on to his arm as soon as he did, she was too afraid to let him attack this intruder, she couldn't even look at the being before them. "What is the demon god doing here?" He asked, and the already stiff silence went electric with shock and fear as everyone's eyes bulged.

"Such a presumptuous question to ask the one true goddess of this domain, do I need your permission to walk my own property?" She looked at him again, scanning him with her emerald eyes as her black lips curled up into a beautiful and cunning smile, revealing her fangs as she released a light huff of black mana.

She had light maroon skin, black silky hair that rested just above her ass and two small black horns protruding from her temples outwards. She was on the same height as himself as well, and she was clad in armour not dissimilar to Ikaris's usual; exposing the top of her bosom, her belly and her mid thighs while on her back rested two dark and skinny bat-like wings.

"Sol," Ikaris called to him sheepishly, knowing that her life was well and truly in danger, she was far too weak as a hero to harm a hair on this monster's head, and her divine powers were simply ineffective against demons, her only option would be to flee in this situation, but turning her back to the demon god was begging to be struck down.

Sol on the other hand was able to fight the demon god, since he was a demigod with divine magic of the demigod species, but now was not the right time, Ikaris was right behind him, any attempt to leave would be a trigger into action, and for whatever reason, this being was stronger than he was, many times stronger, she gave him the same feeling he got from Dr'ul the first time they met.

[The opponent before you is dangerous, you would damn every lifeform in your immediate surroundings to death if you engaged in battle]

"How?" Sol stared at the demon god in horror. "How did she get so strong in such a short amount of time?" He asked himself grinding his teeth and relaxing his arm again, blocking Ikaris from her view completely. "The last time I saw her was when we just arrived, and she was weaker than me back then, so what the fuck, was it a trick from the start?"

"I urge you to not reconsider fighting me after meeting me little demigod," She spoke again, approaching Sol and raising her hand, using her dark claw to easily slice and break the skin of his chin, drawing white blood.

"I have observed your every fight, and I am very interested in the duel we will inevitably have." She chuckled at him, sticking her finger in her mouth and humming at the taste of his blood.

"My visit here is to warn you Sol Vestic, you do not have the luxury of complacency, nor do you happiness, if you fail to meet my expectations, everything you cherish will be annihilated, of course there is an alternative that saves you such heartache; an option that would save your precious unborn and your beautiful wife... to-be."

"And that would be?" Sol asked, feeling Ikaris's grasp on his arm tighten.

"Become one with me, leave everything behind and take my hand, give in to your darkness and take me as your bride instead, I will peacefully leave Arkadia and all you care about in search of a higher realm to conquer if you agree to permanently corrupt your divinity and become a true demon-god, your contract, the passion, the love; I will give it all to you and so much more, I will become yours, Sol...

I will grant you the gift of darkness that washes away even the powers of the mightiest god." She smiled at him with her hand extended while Ikaris felt her heart drop and skip beats at the offer.

"What are they talking about, I can't hear anything, what language is that?" Idria had her brows furrowed and her eyes squinted as she tried and failed to read their lips.

"The language of divinity." Arla thought to herself having read of it once; a tongue that no being other than a god could hear or understand, but Sol was just a demigod, how could he speak it?

"W-Wait Dear-" Ikaris jolted in terror when Sol took a step toward the demon god and reached his hand out, but then to both their shock he bypassed her hand and grabbed her throat instead.

[Warni-]

"Shit up!" Sol snapped at the system silencing it.

"You," he looked at the demon god again. "I'll only say this once, so listen closely you bug-eyed bitch." He squeezed down on her throat, but the demon-god in response grabbed his throat as well with a chuckle and a grin.

"I am listening." She cackled.

"Picking a fight with me, that I can accept, THAT, I can tolerate, but bringing Ikaris into this is your first and last mistake, be sure to memorize this night well, I'm coming for you, I'm going to destroy you and your filthy army with my bare hands, and I'll relish in that destruction!" He roared at her.

"I welcome the thought!" She raised her leg and stepped in his chest sending him tearing through the army in the blink of an eye and then looking up at a frightened Ikaris as soon as she landed on the ground while the multitudes erupted in terrified screams at how massive of a ditch had been made and the countless who had died in an instant.

"Killing you is tempting, but if I did so this soon he would lose his senses and attack me immediately, but he is currently far too weak," She chuckled.

"I suppose... until we meet again then, Ikaris." She laughed while Ikaris stared at the name which hovered above her head, and the information displayed by the system.

The air started roaring with the sounds of dark orchestras and choirs as Ashera stood and opened her hands, laughing at the skies; staring at the gods.

"I have overstayed my visit to this world; dear gods of Arkadia, train him well, grow my little Sol, give me a worthy sendoff, and then rejoice in the name of Sitri before you all cease to exist as you are devoured by me!" She started laughing again in ascention toward the dark portal.

"The end you all feared has long been overdue, but fret not..." She looked down at the army that had once again become quiet and immobile.

"It is imminent all the same!"
