"?!".

Serafina and Lucy, who held the stack of documents in their hands, stopped their discussion as they felt a rather ominous power that crept out inside the academy, giving their heart a restless feeling.

The two figures, who were considered as one of the strongest approved by the people in the academy, turned their gaze towards a specific place where the source came from.

"What was that?".

"...Honestly, I don\'t know".

Serafina briefly gives Lucy an answer while keeping her shrunken gaze straight to the source. Then suddenly, her heart started to beat hard as she recalled the familiar feeling that gripped her soul, making her helpless in front of it. "This oppressive feeling. Don\'t tell me!".

As one of the people who got affected by diluted devil\'s blood, Serafina noticed this familiar feeling when she saw footage her assistant sent to her during the battle across the bridge.

"Lucy called some teacher, and let\'s go to the place where the aura came from!".

As the feeling that gnawed at her heart began to intensify, she suppressed the devil blood within her body to lessen the oppressive pressure the Aura behind the gate for her. Serafina hurriedly turned to her best friend, who was still absentmindedly gazing toward the place.

"...Ah, Understood".

Lucy saw Serafina begin to store away the document in her hands and hastened her face inside the academy hallway. Lucy, who saw her doing that almost reflexively, called out to her to stop Serafina\'s action, for it was against the rule to run inside the academy. But, it was not the time to think about that.

The two of them began to leave the academy building. Lucy took out her phone from her pocket and made a dial to a teacher she thought would fit the situation.

"Ah, good evening, sir. I am sorry for talking to you so suddenly. Well, the truth is…".

Meanwhile, Serina, who kept her gaze in front, ignoring her best friend called, knitting her brows and also prayed that someone he knew would not get involved with this.

A chilling sensation crept down the spine, instinctively urging anyone present to stiffen their bodies. The air seemed to vibrate with a low, ominous hum, resonating with the primal instincts buried deep within.

Soma, with a crimson spear in his hand, unknowingly leaks out his murderous intent and maintains his composure while approaching Mary, who turns to rock.

Every sound and every movement Soma does is amplified to a higher degree, making the land cry in fear within its oppressive aura. The rustle of leaves, the creak of wood, and even the beating of one\'s heart seemed to echo loudly in this silent atmosphere. The killing intent of Soma was almost like a physical presence, pressing down, squeezing their heart, suffocating their breath.

Mary, Leon, and Xiao Lian, for the first time in their lives, feel a great sense of crisis in their lives seeing the furious Soma.

"Die here!".

Soma, who held Mary in his strike range with his aura alone, retracted the spear behind him and prepared to thrust it anytime. Mary, who sensed a great danger upon the stance Soma took, bit her tongue, letting out blood to smear her lips, to free her from the paralyzing feeling she had, and tried to flee from the place using her wings. "This is no joke. Who the heck is that first-year student?

That boy was so freakingly scary and almost suffocated me to death with his aura alone. He is also dangerous at the same time. I can\'t let myself get killed here. I must report this to my mother dearest that there is someone stronger in the academy".

Mary turned her back swiftly and infused a lot of mana toward her wings, but a heavy thud accompanied by the rustling grass resounded as Mary, who thought she had succeeded in running away, looked at the green carpet that filled her eyes. "What is happening?".

As she realized she was lying down on her stomach. Mary tried to support her body to a crawling position, but she couldn\'t get a grasp on her right hand. She turned her gaze to the side, and she saw a pool of blood begin to smear her skin and uniform. From the corner of her sight, she saw her half-remaining right hand, and wings lay not too far away from her.

There\'s an initial stillness, almost surreal disbelief as if her mind refuses to accept what the body knows the truth. Mary knit her brows as she grits her teeth upon a searing pain that suddenly erupts through her nerves, radiating through the body with a ferocity that blurs vision and thought.

"Aaack!".

A howl of a wounded beast echoed in the place as it sent shivers to the other two people who witnessed Soma\'s merciless action. Leon, who saw that happening, blocked his mouth, and Xiao Lian calmly knitted her brows as she assessed the event that transpired in front of her eyes with open eyes and also saw the new side of Soma he rarely showed.

But, regardless of how ruthless Soma is in front of her, she thinks the demon deserves it.

Soma pulled back the spear in his hand and, with a swift motion, struck down the other limbs of Mary. With each thrust he did, he obliterated the joint, and a pained roar escaped her mouth, making the entire place shake in terror.

"Ugh, Kuh! Stop please, no. Save me, mother dearest".

Mary, who is forecasted as one of the beauties in the Academy, is currently in a mess with her bloodied mouth, tears, and snot filling her entire face, begging for mercy while shouting her creator\'s name. The trace of her beauty was long gone, and now what had shown to the world was an obscenity accompanied by a howling woman in grief and in fear of losing her own life.

As she desperately crawled with her lost limbs, Mary saw a shadow of death looming toward her body, making her vision dilate in horror. She didn\'t dare to turn her back and thrashed away from her crawling position.

"No, please, I want to live. I\'m just following the order of my mother dearest. I just want to have fun sucking other males\' vitality and taking some of their life essence. I swear, I never kill someone in this place. I just want…".

Without listening to one of her pleas, Soma thrust the spear, and it plunged toward Mary\'s chest, destroying her heart. It penetrated her chest till the spear struck the ground, instantly making her body go limp, unmoving.

[You level up!]

After seeing the translucent window that notified him of the demon\'s death, Soma retracted the spear from Mary\'s dead chest and swung it to the side to get rid of the remaining blood that stuck to its blade. He sighs as his raging mind calms down and gives another spare glance at Mary.

Soma turned his back and found himself being gawked at by five individuals who opened their eyes in wide shock, seeing Soma kill a person without any shreds of hesitation, as if he was breathing.

In front of him, he saw Serafina, Lucy, and Teacher Lee, who looked at him with his stern gaze. Soma overlooked their coming, and this must take into a note that he needs to improve in the future.

Teacher Lee began to scan the surroundings as he saw the body of a demon and scattered limbs across the land with a trace of blood, knitting his brows as he turned to Soma.

"Do you care to elaborate on what happened, Soma?".
