A desolate whistle echoed through the catacombs-like dungeon as a group of medieval-armoured knights marched their way through the dungeon, taking out any monster which impeded them with the monsters turning into violet-purple mist upon death. Stationed in the vanguard, the demi-human cat knight commander signalled for the other knights to halt as he arrived at a large open room.

"Grand Witch Abigallia, we've arrived at the rest spot before the boss chamber," the knight commander stated as he turned to face Abigaillia. Floating above the squadron of knights while carrying a sleeping person in her arms, Abigallia gracefully glided over the rows of knights before landing beside the knight commander.

(Abigaillia is a super tall adult female witch[basically just a human but modified to be superior with magic]; she has super long frilly pitch-black hair, black ring-shaped eyes with violet purple heart in front of the rings, a busty chest, wide hips, and tanned skin)

(Abigaillia is wearing a goofily large dark ocean blue witch hat, a golden collar with a cyan crystal circle on the front, a dark ocean blue slit dress, black leggings, and metal boots)

"I appreciate all of your assistance, we can leave the rest to my little angel," Abigallia said with a sultry voice as she gently stroked Kousako's forehead.

(Kousako is a slightly below average height teenaged humanoid[they look like a normal human] with an appearance which can't be assigned to male or female; they have slightly long super curly dark ocean blue hair, super fair skin, slightly big hips, firm thighs, and a thin pale purple tattoo around their eye which looks like eye shadow)

(Kousako is wearing a simple/plain black headless spandex bodysuit)

As Abigallia continued to baby the sleeping Kousako, the night commander removed his helmet and itched the back of his cat ear while he signalled to his knights to set up camp.

"About that, Gran-".

"Just call me Lia, sweetie, we aren't in a formal setting after all.". The knight commander scrunched up his mouth before defeatedly exhaling.

"... understood, Lia. As I was saying, are you sure it's okay leaving the boss chamber to... um," the knight commander uttered as he perplexedly stared at Kousako. As the knight commander's confusion continued to rise, Abigaillia couldn't help but smugly snicker as she cradled Kousako.

"Having a hard time identifying and categorising my little angel?" Abigaillia asked proudly. The knight commander sheepishly glanced to his side and rubbed the back of his head.

"Seems that way, Lia". Abigaillia cheerfully grinned at hearing the knight commander's response.

"You don't need to feel bad about not knowing, it took Mouzo-Hala a whole month to figure out what Kou is," Abigaillia explained, "And to answer your question, my little angel will be perfectly fine.". The knight commander simply nodded his head to Abigaillia's words before a loud bang stole his attention. At the same time, Abigaillia paid the sound no mind as she continued to focus on Kousako.

As the knights hurried to the door and set up a defensive stone wall using magic tools, the towering stone door continued to shake as a cacophony of deafening bangs collided against the other side of the door.

"Is the boss attempting to break out and attack us?" a knight asked in shock as he readied his steel sword. The knight commander glanced to Abigaillia, and mentally groaned at seeing how unbothered she was being.

"You don't need to worry, a boss monster will never leave the boss chamber, the monsters attacking the door are mostly the boss's minions trying to get after being startled from sensing my little angel," Abigaillia stated smugly. The knight commander stared at Abigaillia in surprise at hearing her words, and he pondered on how strong someone needs to be to aggro boss-subordinate monsters from a different room.

"It seems I really was worrying for nothing," the knight commander remarked, making Abigaillia cockily smirk at her angel getting praised by someone.

"I suppose it's in everyone's best interest if I wake Kou up, now wouldn't it," Abigaillia remarked before she lowered her mouth to Kousako's ear and whispered into their ear. Kousako's violet-purple with crystal textured eyes shot open before Kousako turned their head in the direction of the stone door.

"Sweetheart, would you be a dear and deal with those pesky monsters for me?" Abigaillia requested. Kousako stared at the cracked stone door as the cracks covering it grew with each strike of the monsters behind it.

"People in the way," Kousako murmured. Abigaillia glanced over at the knight commander, making the knight commander nod.

"Everyone fall back," the knight commander ordered. The other knights instantly followed the commander's orders and vacated the area around the stone door before the stone door exploded into dust and allowed the trapped monsters to spill into the room. The monsters continued to flood into the room, making the knights raise their weapons while bracing themselves for their commander to order them to attack.

"The coast is clea-". A violently strong sonic boom blasted past the knight commander, almost knocking him off balance, and knocking over the knights as Kousako blasted past them at blinding speeds. In the blink of an eye, Kousako lunged at the monsters before unleashing a flurry of lightning-infused sword slashes and dicing them into pieces. The knight captain stood in bewildered awe as he watched the diced monsters burst into dense violet-purple mist which swirled into Kousako's tattoos.

"Impressive...," the knight captain uttered before Abigaillia teleported over to Kousako. Abigaillia threw her arms around Kousako, pulling them into a bear hug and slightly burying them in her chest.

"Way to go my little murder machine. You've gotten so strong now I could only tell what cursed echelon you were using because of the lightning~," Abigaillia said excitedly whilst Kousako had an emotionless expression on their face.

"Murder machine?" the knight commander asked puzzledly as he walked up to the duo.

"It's a figure of speech on the mainland," Abigaillia said.

"I see," the knight commander responded before he turned to the knights, "Alright you lot resume setting up the temporary camp.". Abigaillia gave Kousako one last hug before she released them and allowed Kousako to land on their feet.

"Alright, sweetie, could you go deal with the big bad demon lord for me?" Abigaillia requested politely. Kousako nodded before turning and marching through the doorway leading to the demon lord's boss chamber. Abigaillia and the knight commander watched Kousako trot their way into the boss chamber with any monsters that approached them bursting into a dense violet-purple mist. The knight commander allowed his shoulders to sink before he shot up as something clicked in his mind.

"Did you say cursed echelon?" the knight commander asked worriedly. Abigaillia turned to the knight commander with a suffocatingly overbearing smile, which even managed to make the commander flinch on instinct.

"Is it such a surprise for my little angel to have one?". The knight commander adverted his eyes in dismissal and turned away from the boss chamber

"I suppose it was a dumb question," the knight commander uttered as he walked off, leaving Abigaillia to watch Kousako at her leisure.

Within the boss chamber, the imposing and towering silhouette of the demon lord filled the room with a sprawling shadow. As Kousako strolled towards the demon lord, the demon lord rose from his throne while condescendingly cackling with his booming voice.

"How insulting, not only has that idiotic witch come without the hero but she instead sends a pouting brat," the demon lord remarked condescendingly as Kousako glared at the demon lord with murder plastered all over their face.

"Take it back," Kousako uttered emotionlessly as a violet-purple mist formed beside them, only making the demon lord's cackling turn into full-blown laughter.

"So you can use cursed essence, haha; that witch really is a deplorable perso-". A condensed wave of fire erupted through the chamber and flooded every inch, leaving scorch marks everywhere as the scorched corpse of the demon lord crashed in front of Kousako before he exploded into cursed essence. As the abundant cursed essence funnelled into Kousako's tattoos, Kousako's angered expression phased back into their emotionless one.

"Amazing my little sweet pea, that meanie didn't know what hit him," Abigaillia said with an upbeat tone. Kousako placed their dark grey katana with a black handle and a black hexagon-shaped/crystal-textured hand guard into a cursed essence mist before turning to face Abigaillia, her face beaming with joy and giddiness as she looked at Kousako's face which she thought of as goofily adorable. Abigaillia placed a hand on Kousako's head and rustled their hair, causing Kousako to close their eyes and hum like a purring cat.

"And with this one defeated, that means there are no more demon lords for you to fight for now, sweetie," Abigaillia said as she raised her hand away from Kousako only for them to grab her hand and place it back on their head. Abigaillia was slightly taken aback by Kousako's desire to keep her hand on their head, but despite the surprise, Abigaillia could not help but contently smile.

"Sweetie, could you hand over Kokuakyou?" Abigaillia asked cheerfully as she held out her hand. Kousako nodded and conjured another mist of cursed essence before they reached into it and pulled out Kokuakyou: a purely metal black shortsword with holes running through the middle of the blade.

Kousako handed over Kokuakyou and Abigaillia stared at Kokuakyou as her expression turned to a pained smile. Grey gas began to seep out from Kokuakyou's holes, and Abigaillia pulled Kokuakyou back, her breath stifling as she thrust the sword forward. Kousako's body jolted from the protrusion and they glanced down at their shallowly punctured chest as it slowly began to petrify. Abigaillia hung her head low and sombrely whimpered.

"looks like I couldn't even half... well you get the picture, sweetie...," Abigaillia uttered with confliction crawling through her inflexions as she lowered her head even lower to the point her hat fell off her head. Abigaillia sighed as she reached down to grab her hat but froze as she felt a small hand touch her head. She gazed up through her hair to see the partially petrified Kousako patting her head.

"Thanks... for understanding, sweetie," Abigaillia uttered as she stood up straight and placed her witch hat on her head, "But how could I live with myself if I allowed my babies to participate in the upcoming war and kill non-monsters?". Abigaillia closed her eyes as she removed the collar from around her neck and placed it around Kousako's petrified neck. As the petrification began to encircle Kousako's face, Abigaillia gave Kousako one last content but pained smile before gently kissing Kousako on the forehead.

"For you, it won't feel very long and once you get free, which I know you will, promise me you'll find your siblings... although I guess it won't be that hard since you're the last one being petrified," Abigailila uttered as she wiped a tear from her eye. From Kousako's view, the outer edges of their vision slowly darkened with that darkness crawling over their eyes until Kousako's vision went completely blind and Abigaillia's voice faded into nothingness.

Kousako remained in the silent confines of the mental nothingness brought on by being petrified. As Kousako considered going back to sleep, Kousako began to hear the faint voice of a female complaining about something not working.
