Transmigrate inside a Web Novel as a Side Character.

The man, who suddenly heard Soma's voice beside him, received a tremendous blow on his left jaw that shook his brain, halting his thought process. His body was being flung away because of the strength Soma had exerted.

"Soma?".

Serafina, who slightly regained her breath with knitted brows, raised her gaze and saw Soma clad in a golden aura, standing upright while gazing at the man who lay down writhing in pain.

"Are you alright, Sera?".

"...I'm a little bit not okay".

Soma helped her to regain her footing and looked toward the other two girls. He saw Xiao Lian, who had already recovered from the blow but still slightly contorted her face, and Hina was still lying unconscious, not far from him.

"Sera, take care of the girls and the kidnapped children, please".

"What about you, Soma?!".

Serafina's body tensed as she heard Soma's low tone, which gave the chills around her body. Slowly, she separated herself from Soma while taking some potion from her storage.

"...I don't know, maybe I should have viciously killed that man".

After He finished with his words, Soma locked his attention toward the man, then raised his feet, approaching the man who was still maniacally caressing his cheeks the place Soma had punched.

"Ahahaha, good, this blow that I received, your raw feeling. I can feel it directly on my skin; it makes my heart race to think about it. Haha…".

"Shut up, Freak!".

Soma closed the distance between them with a single step and intended to deliver another blow with his leg, but the man jumped off from his place, spread his bat wings, and observed Soma from above.

The man began to sneer, for he was pleased, being chased by Soma. Soma's face turned serene as a tremendous amount of rage-fueled his heart and reddened his eyes. He shifted his gaze downward, clenching his fists hard, and used his final card to kill the man.

An ominous aura began to leak from Soma's body. It made the surrounding atmosphere turn heavy because of its appearance, a malice. The red aura that clad his body began to clash with the golden aura that had manifested earlier.

Soma's muscle tissues begin to tear, and it heals again. The process happens several times, creating an endless loop of destruction and recovery.

However, the thing that he does not expect is. From his back, he felt a tremendous force that condensed into a wing similar to the man, and from his side skull, a small pointy goat horn protruded upfront, making the people inside the room open their eyes in shock.

The man who saw Soma's change felt pleased initially, but gradually, his joy turned to horror. The figure he looks at now is far from the ideal image of the boy in his dream. His body starts to tremble, and without knowing the reason, his lower part feels weak, as if forcing him to kneel in Soma's presence

With a pale face, the man pointed his index finger and spoke with a stammered voice.

"Y-you, W-what are you?".

Soma, who heard the man's words, lifted his gaze, and regret filled his cold and lifeless eyes, looking toward the man. At first, Soma thought that he could deal with him without using this method, but he was wrong.

Because of that, the people close to him are injured, and the most important part is that he swallowed his own words for fear of being hurt or afraid that his other self took control. "I should have done this since the first time, for I am the one in control".

{Kekeke, ahahaha. That's right, use my power more, drown yourself in the destruction power within you, with that you can obliterate everything that stands in your path and…}

"Shut up!".

A crackling tone from the devil inside his body reverberated in his brain before Soma shut it down to get rid of the disturbances it caused.

The floor beneath Soma began to crack until it gouged, creating a small crater upon the release of the consecutive technique. Hundreds of wild and untamed crimson bolts clad his body, scattering across the atmosphere and making it tremble in terror.

***

On the other side of the place, Xiao Lian, who saw Soma's appearance change for the first time, stoned and kept gazing at his unmoved back. The images of wings on his back and the small horns on his head ceased her thought processing.

She was too stunned to see Soma change to become something that should have been Humanities' enemy.

"Xiao Lian?".

Serafina called her from behind, watching her expression, which was mixed between shock and grief. However, Serafina, as a person who knew his identity. "This was something Xiao Lian must have seen and known if she wanted to stay beside him in the future".

"Xiao Lian!".

Xiao Lian, who blanked for a second, jolted awake because her body was yanked to the side, and she met Serafina's determined eyes while bringing two kids on her shoulders.

"Xiao Lian, forget about them and focus on the things in front of us; let us save these poor children first; as for what kind of question you want to ask, save that for later and face Soma directly to know it."

Her stopped thought began to move as she saw the faces of unconscious children on Serafina's shoulders sober her up. Xiao Lian shook her head to disperse the negative thoughts she had in mind and began to help Serafina in rescuing the children.

***

The man who saw Soma's transformation knit his brows as he began to transform. His body began to bulge, and his size doubled from the moment before. His skin turned red with a shade of black around his limbs, mimicking the appearance of gloves.

Horns began to protrude from his forehead, pointed upward, and his teeth turned rigged like a saw, and the oppressive aura that leaked from his body multiplied tenfold. However, that still wasn't enough to shake off his instinct, which kept warning him about the actual danger in front of him.

The demon spread his hand wide, and the cluster of a black flame began to float around him as he was preparing to release it, but Soma was already gone from his place.

"This is payback from earlier".

Soma, who appeared behind the demon, delivered his kick toward the man's spinal cord. With the power of the Third steps, the sound of broken bones echoed inside the room, sending the man to the floor that cracked upon the collision.

"Aakh!".

Still not finished with what he was doing, Soma appeared before the demon then grabbed the demon's throat, lifting him up to face his eyes. With a clenched fist, Soma with clenched right fist dug the man's abdomen deeper with his straight punch.

"Gahak!".

The demon threw up a mouthful of blood because that single punch had obliterated some of his internal organs. The blood that had been coughed out spilled from his mouth, smearing Soma's left hand, which was still holding the demon's throat, blocking his airways.

He never thought that Soma had this much power hidden inside him. The sheer oppressive power that overwhelms him is equal to Ira, one of the Demon Lord's seven direct underlings.

"Hehe, You monster…".

Without minding the words, Soma released his grip from the throat and let the demon feel a sense of floating for a moment before his body bent into a v-shape and was blown by his powerful kick.

Without stopping, he continued his attack, creating an afterimage; Soma accelerated, arrived behind the demon's back, delivered another kick toward his back head, and sent him in another direction. Like a ball, the demon's body just got tossed in every direction.

Each timed his kick connected bone shattered flesh tearing, and blood splattered across the room, creating a symphony of madness.

[You gained exp!]

[You level up]

[You earned BP +5]

Even though the translucent window already notified him of the demon's deaths. Soma kept kicking the lifeless body until its whole bones were shattered, and the demon's body got soft.

Soma starts to notice the change in the demon's body. Soma kicked the demon's body upward, lifting it toward the ceiling. Then, while exhaling, he concentrated all of his power into his right leg and lunged above to deliver his final attack.

"Disappear!".

A moment of silence happened before a blinding light that shone brightly inside the room became the foreshadowing of the destruction. An earth-shattering boom resounded, destroying everything in its path. The destructive light didn't stop until it reached the clouds above, dispersing it into a spiral.

Serafina and Xiao Lian, who happened to stay inside after delivering the last children outside alongside Hina, saw the destructive Might Soma had unleashed. They stare, jaw dropped at the light that pierced through the building roof, while also amazed by the sheer power Soma holds in his hand.

After the light that shone brightly a moment ago began to dim, they saw Soma, who had spent his entire power on that single strike, falling by gravity, not making any movement that made their face turn pale.

"Soma?!".

Serafina, who shouted, began to create small whirlwinds that propelled her body toward Soma; as for Xiao Lian, she slightly hesitated before biting her lips and approaching their side.

With the help of the wind magic, Serafina arrived in time. She snatched Soma's body away before creating another whirlwind to soften their fall.

"Soma, are you okay?".

After reaching the floor, Serafina checked his pulse and breathing, then gently caressed Soma's cheeks to check his temperature.

"Haa, Sera, p-please…?".

With a weak breath, Soma recognized the voice within his hazy consciousness, squeezing his throat to tell her about something.

"What is it, Soma?".

Serafina slowly places her ear near Soma's lips to hear his words.

"...S-search the building!".

After forcing his lips to move, all of his energy was wasted, and his consciousness was swallowed by the abyss.

"Okay, I will definitely do it, hm? Soma, are you okay? Soma, wake up!".

"Senior?".

"My lady, we have come to your aid".

"Soma, Please wake up. Hey Soma!".

Xiao Lian and Volet finally arrived at the scene; Serafina was frantic because, seeing Soma had stopped moving, drifting toward his dreams.

"...Hey Soma!".

Inside the room, while basking in the sun's grace, a wail from the girl closed the curtain of the hideous project that the demon conducted in the Ark, which made the other demon notice the unconscious boy.
