Transmigrate inside a Web Novel as a Side Character.

As the battle unfolded for over a minute, Soma kept defending the hurling attack from the man until eventually. He saw an opening from the man, and whether it was because both of them needed to catch a break or because of some trap the man had laid for him, Soma couldn't let this miss.

Soma ignited the Martial Saint technique and distanced himself to regain his breath and stance. With a ragged breath, Soma saw the man who kept his composure, looking toward him with stars in his eyes.

Then, suddenly, the man stood upright while clapping his palms together, giving Soma a sense of danger upon the creepy action the man took.

"Magnificent, You are really something. I am amazed by how you handle the situation, and it is such a waste to kill you here".

"Ha?".

The man suddenly extended his right hand and softened his expression by placing his other hand on his chest.

"Would you be kind enough to join our side, dear?".

"?!".

Soma is stuck because of the incomprehensible words the man has said to him. Soma's brain halted and refused to receive the word that went through his ears.

All of a sudden, his pupils dilated into a dot as the memories and rage he held deep inside began to resurface, becoming a fuel that burned his hatred to another level. Soma summoned his equipment, and his limbs began to be covered by his purple gauntlets and boots with white veins.

His body began to tremble, and his fists clenched tight, making a crackling sound because of the gauntlets. The aura surrounding him burst forth and creates a whirlwind of crimson bolts that dance wildly in the room.

[Oni Wrath activated]

"Second steps - Lightning Descent".

Soma's body was strengthened, and the rumbling of the crimson lightning surrounding him began solidifying into his feet, coating its boots and enhancing its performance further.

"Woah, Ahaha,,,".

The man who saw Soma's change in demeanor and power opened his eyes wide and spread his lips in pure joy because the kid had surpassed what he had been thinking. His cheeks began to turn into a shade of pink, and his body was tingling with pleasure that he had never experienced when dealing with other people. The only one who can turn him into this kind of state is Ira.

However, to think that there was someone out there who could flip his switch into madness, he felt so pleased that his heart melted and eyes widened in pure ecstasy.

"Third Step - Lightning strike".

A thundering roar occurred, and it made the surrounding wall and atmosphere shake in horror because of the sheer power Soma held in his lean and robust body. The crimson thunder that coated his feet began to scatter across the space, creating a magnificent pulse that looked deadly.

"Ahah, Ahahaha, ahahahaha. Good, you are truly magnificent. This piqued my desire furthermore to have you, hahaha. Come let me receive that pure emotion of yours".

"Kuh!".

[Extra Skill Adapt activated]

[The user's body is burdened by the great power he holds, and it gradually tears bit by bits the user physically]

[Nullifying the pain 100%]

He was using the Martial saint Technique without any help from anyone or any power. Soma's body seems to have taken a huge toll because of it; however, after his body starts to numb about the pain, Soma, whose hair and clothes swayed by the aura he possessed, tense the muscles around his body while preparing his stance and concentrates his power into a single point.

Soma, with his sharpened mind and sense, felt that time had slowed down. The world around him turned dull and was replaced by a gray color that let him focus on his enemies, who were covered by a menacing red aura.

However, after he saw the ecstasy expression around the man's face, Soma knit his brows as he began to change his plan.

[Extra skill Puppeteer activated]

[The user drew the power of Saint toward his body]

"Martial Saint, lend me your power".

A faint gold of Saint power began to mix in the crimson storm around Soma. Soma could feel that his broken flesh was restored at a fast rate, and his consciousness was refreshed to a normal state.

From within his body, a wave of golden aura began to show its might, mixing with the crimson power and turning his aura into an orange.

"Huh?!".

Now, after witnessing the sudden change in Soma. The man's expression turned blank. He felt a great sense of danger upon seeing the current Soma.

Soma, with lightning-fast movement, accelerated toward the man. In the world that turned still, Soma saw the man was a couple of meters away from him. His feet began to leave the ground as he propelled himself up and spun in the air to increase the momentum of his attack.

Then, when they were facing face to face, Soma, helped by the momentum he carried in his body, swung his right leg downward, creating a massive power of the tempest that obliterated everything that stood in its path.

The whole building shook, no, the atmosphere itself trembled, as a thundering roar that broke the surrounding air blasted into bits and destroyed a part of the building before it disappeared into thin air, leaving a huge gaping hole that made it hard to believe that power came from a boy.

"Ha, ha, ha…".

Soma, whose body was released from his power, dropped down on his knees. He was gasping for breath because of the sheer burden on his body from the usage of skill and recklessness.

[Oni Wrath deactivated]

[Extra Skill Puppeteer activated]

[Penalty deflected by Puppeteer skill]

He used the skilled puppeteer to force his paralyzed body to stand upright, refusing to let go of his wariness despite releasing such a terrifying attack a moment ago.

With gritted teeth and sheer determination, Soma held on to his standing position while scanning his surroundings, which were covered by the thick black cloud that blocked his sight. Slowly, because of the help from the natural airways that came from the massive hole in front of him. It helps bring the cloud of dust away, and the room regains its clear views.

"...As I thought".

As he had already predicted, the man was still alive, but Soma saw that half of The man's limbs were obliterated, and it was being charred into a black substance. The man was lying down on his back while recalling the earlier attack.

The man's body began to shudder in thinking that he could withstand that last attack. At first, he was confused about what actually happened. Because the moment Soma released his technique, with his superior sense in battle, the man was sure he could withstand that attack. But, after a golden power mixed in, his instinct began to scream, ordering him to avoid it at all costs.

It was weird and terrifying at the same time because it seemed the boy had something that his kin feared, something that could make him, an advanced Rank-S demon, tremble in fright.

The man concentrated his power on his missing left limbs. Then, using his right hand, he cut the charred left hand and leg before taking something from his storage in the form of a necklace, which was hidden by the fabric. He held a tiny vial from his right hand that filled with a drop of rainbow color fluid before he shattered the vial and let the content flower to his lost limbs.

Soma, who saw the man's body was covered in rainbow colors, opened his eyes wide in surprise because of the resource the demon had.

"Impossible, is that, Elixir?!".

The man's losing limbs began to regrow back into his normal state. He began to clench his fist and twirl his ankle, checking if there was an anomaly, but it seemed he was fully restored to his normal state. The man slowly stood up and patted his clothes, which had been dirtied by dust.

"Very well then, it seems I have no choice but to kill you!".

"?!".
