Chisato Hasegawa. The mysterious beauty with emerald orbs walked down the street with an angelic smile on her face. As she walked, she played with the earring that was on her left ear before giggling to herself.

'I wonder what I could make for dinner...just me and Y/n, huh...' Chisato thought as a small red tint appeared on her cheeks.

Suddenly, she stopped in her tracks when she felt a familiar presence. Her face twisted into one of dissatisfaction as a male spoke with slight anger but also satisfaction in his voice.

"You are getting very attached to that abomination..."

"Oh? And who are you to tell me who I can and cannot be with, Ornis?" Chisato asked and turned to face the male.

Ornis's eye twitched but he kept his calm smile.

"The rest of Gods had seen fit that I am to be your watcher, but, when you involve yourself with Demons, I can assume that you are planning something. Especially with the likes of that Half-Breed. You wouldn't want me to tell the rest of Gods now would we?"

"I have no time for your boring talks, Ornis. I have somewhere to be." Chisato said with a bored tone before turning to walk.

Ornis grit his teeth in anger as he balled his fists.

"And do me a favour. Stay far away from Y/n...Or else..."

"Or else what? Are you afraid that I will tell him who you really are, Afureia? Or perhaps or should tell him the whereabouts of his mot-"

"You'd best watch your next words wisely, Ornis."

Ornies stepped back as Chisato looked at him with glowing blue eyes and the tips of her long black hair were golden. Chisato's eyes and hair went back to normal, with a last glance at the God in disguise, she walked away. Once she had reached the front door of her apartment, the sound of a glass shattering was heard. Chisato quickly made her way inside and saw Y/n staring at the shattered plate with a blank expression.

"Huh...?" Y/n said softly.

"Y/n?" Chisato spoke softly and he looked at her.

"Hasegawa-san, I...I'm sorry." He said softly and began to pick up the pieces of the plate.

Chisato sighed in relief and walked up to him. Y/n winced a little as a small piece of the plate cut his finger open.

"Are you okay?" She asked with a soft gentle tone that made Y/n's face light up/

"Y-Yeah. J-Just cut my finger."

"Let me have a look." Chisato then took Y/n's hand into hers and he blushed as he felt her soft skin. "Hmm...It's not too deep. A bandaid will fix this. Just wait for here for a second."

The dark-haired beauty then walked to her room and after a few seconds had gone by, she came back with a plaster. She held Y/n's hand underneath the tap and washed the blood away.

But, while Chisato focused on his hand, Y/n couldn't tear his eyes away from her. Her entrancing features. Her bright green eyes. Chisato glanced at him from the corner of her eye and giggled softly.

"You know, it's rude to stare."

"Huh? O-Oh! S-Sorry. Uhm...I didn't mean too." Y/n said looking away from her with a red face.

"Don't worry about it. If it makes you feel any better, I stare at you too sometimes." She said surprising him

"R-Really?"

"Yeah. You have a cute sleeping face." Steam then appeared on top of Y/n's head and he couldn't even form a single sentence. "And there we go. All finished." Chisato said after putting on the plaster.

"Uhm...Uhh! I...I....I need the bathroom!" As quickly as he could, Y/n walked straight past Chisato and went to the bathroom to wash his face. 'Ugh. What is wrong with me? I'm getting all flustered. Not even doing sexual stuff with Maria, Sheila and Lucia made me so flustered...Is this...Am I falling for Chisato? Well, what's not to like. She's beautiful, smart, funny and so caring.' Y/n's entire body shuddered and his eyes widened. 'What was that? This power I feel...It feels like it's Wilbert's...but...Why? I thought he... it's smaller than his and it's difficult to pinpoint it....Perhaps I should head back to the Demon Realm.'

Making up his mind, Y/n walked out of the bathroom and saw Chisato sitting by the kitchen counter.

"Uhm...Hasegawa-san..." he started with a nervous tone. "Uhm...I think that I am gonna go back home."

"I...see..." Chisato said with a hint of sadness in her eyes.

"B-But will definitely come and visit you. I promise!" Y/n said quickly and Chisato stared at him.

"Chisato."

"H-Huh?"

"Chisato. No more, Hasegawa-san. Chisato." She then walked up and stood right in front of him."

"B-But, Hase-"

"CHI. SA. TO."

"Uhm....Chisato...san." Y/n said with a nervous stutter.

"Hmmm. It's a start." His eyes then widened when Chisato leaned forward and pressed her lips against his forehead.

"Uhm...Good...bye...Chisato-san." Y/n said softly and she nodded her head with a beautiful smile.

After creating a portal in a dark alley that led to the Demon Realm, Y/n quickly made his way to the castle. Suddenly, he could feel the air was different. All the guards and the maids in the castle were on guard.

"Y/n!" He heard Larz shout and he turned around.

"Larz. What's going on?" Y/n asked and Larz shrugged his shoulders.

"Don't know, but one of the Guards came to the Orphanage. They came looking for me and you."

"Us?"

"Yeah. He said that Ramusas-sama wanted to see us for something urgent. Come on."

Larz and Y/n quickly made their way to Ramusas's Office, which was Wilbert's before he passed. As he stood in front of the door, Y/n took a deep breath in before opening it. Instantly, he could tell that something was wrong. Ramusas had a deadly serious but dark expression and Lucia...

Her face was disturbingly stoic. Usually, whenever she would lay eyes on Y/n, a mischievous glint would appear but this time, there was none.

"Uhm. You were looking for us, Ramusa-sama?" Larz asked and Ramusas could only nod his head.

"Y/n...Larz...I...I have some bad news. My brother, the previous Demon Lord...Secretly had a daughter and she was raised in the Human world." He said surprising the two.

'What?! W-Why didn't Wilbert tell me? D...Did he not trust me?' Y/n thought with sadness in his heart.

"The reason why he kept it a secret was because...His Daughter has inherited his power. Fearing that she might be used in the Demon Realm, Wilbert had sent her to the Human World along with his most trusted Servants to raise her. Those two were Ruri and Haru." Ramusas said, continuing to surprise the boys.

"What?! Is that why they were in the Human Realm? To protect Wilbert-sama's daughter?!" Larz asked shocked.

"Why are you telling us this, Ramusas-sama?" Y/n asked with a curious tone.

"This is going to difficult to hear but...Maria was tasked with protecting Wilbert's daughter should Haru and Ruri fall...and that seems to be the case."

"No..." Larz said with wide eyes as he fell to his knees in despair.

Y/n couldn't believe his ears and he could feel his heart sink into despair.

"Haru? Ruri? They're..." Y/n dared not to finish his sentence.

Ramusas nodded his head with a dark gaze before continuing.

"Maria and, from what we had learned, Naruse Mio have gone into hiding...But that's not all. Sheila has gone missing as well."

"....What...?" Y/n asked with a blank tone.

"It seems that whoever it was, was very skilled. Some of the guards and maids were found knocked out by a mysterious assailant."

"Who was it?" Larz asked with gritted teeth as anger began to boil up inside him.

"It was most likely the Demon Lord Faction. They could've kidnapped Sheila and use her as a bargaining chip for Naruse Mio." Said Ramusas as Y/n's eyes were shadowed. "If we could go against the Demon Lord faction, we would, but we simply don't have the numbers or our previous support. I hope you tw-"

He was then cut off when Y/n's body started to glow slightly. Unbridled rage began to boil inside Y/n and his demonic appendage glowed a bright blue. Before Ramusas and Lucia could do something, at blinding speeds, Y/n slashed open a portal and walked into it.

"Y/n! Stop!" Ramusas shouted but his words fell onto deaf ears, instead, he looked at Larz with a serious expression. "Larz. I know how you feel, but right now, Y/n needs you!"

Larz grit his teeth before nodding his head with determination. He got up from the ground and ran after Y/n, but his eyes widened when he saw a large stone castle in front of him.

"This is! Lundvall Castle where the new Demon Lord resides! Y/n!"

On a throne located deep inside the stone castle, sat a tall young man with tanned skin, purple hair and blue eyes. Standing next to the throne was another young man with light-green hair with cat-like ears and horns on the side of his head, pointing downward and red eyes.

"Anything, Balfear?" The tanned male asked.

"Yes. I have gotten some news, Leohart-sama. I've been hearing rumours from the Council saying that the previous Demon Lord, Wilbert, has had a child. She was raised in the Human World."

"I see. So, this girl might inherit Wilbert's magic, huh? How interesting." Leohart said with hands underneath his chin as the gears in his head started to turn.

But before anything, could be said and done, the castle shook violently and small stones fell from the ceiling. The door leading to the throne was then blasted open, sending splinters flying everywhere.

"Who dares?!" Balfear asked with a glare.

In the dust, a silhouette of a person could be seen. The person had a katana in their right hand with a faint blue glow around them.

"Where...is...she?" Y/n asked with gritted teeth with his eyes shadowed.

"DO you know where you are? You're intruding on the Demon Lord. Surrender immediately." Balfear said and Leohart's eyes widened.

'This presence! This aura!' He immediately stood up from the throne with a serious expression and it seemed to shock Balfear.

"Tell me...Where...is Sheila..." Y/n said with his voice becoming more demonic and distorted.

"We do not know who you're talking about. Surrender immediately and we will let you go." Leohart said and the aura only seemed to grow bigger.

'Lies....Lies...LIES!'

Kicking off the ground and cracking it in the process, Y/n dashed towards Leohart and gripped Yamato tightly. In a blink of an eye, a large broadsword appeared in Leohart's hands. He held it up and blocked Y/n's blade in the nick of time. The strength behind his swing sent the dust around them into the air. A massive shockwave blew out around them and Balfear looked at Y/n in shock.

Leohart pushed Y/n back before kicking him in his chest. Y/n's eyes widened as he coughed out alive and floor across the room. A magic circle appeared underneath Y/n's feet and he used it to recover in mid-air.

"How barbaric. So blinded that he doesn't even realize he will lose against Leohart-sama." Said Balfear as he adjusted his glasses.

"It seems words won't be enough to calm you...in that case, I will have to take your life here. Sad, for one so young to die...but I cannot let you fall into their hands." Leohart said with a soft tone.

Leohart was engulfed in a powerful dark aura and his eyes turned white while his sclera turned black.

"Loki. COme to me."

With a swirl of black energy, a black demonic sword appeared in Leohart's hand and Y/n's entire body began to tremble in fear.

Before He could even react, Leohart, who was a few metres away, was in a blink of an eye in front of Y/n.

'....Is this how I die? I didn't even find Mom....I...Chisato...I'm sorry, but I don't think I will be able to keep my promise...'

It seemed like time slowed down for Y/n and his life began to flash before his eyes as the black blade drew closer to him.

'pOWeR....MOrE....pOwER...dO YOu wAnT iT?'

Spoke a demonic voice and Y/n found himself in darkness. Slowly floating in front was Yamato, engulfed in a small blue glow. Y/n walked forward and reached his hand out.

"Power....I want it...I want more power...Without it, I won't be able to protect anyone...let alone myself."

With a voice of desperation, Y/n's plastered finger was an inch away from the blade, but he stopped when a pair of arms wrapped around him from behind and he felt two large squishy objects on his back. He looked back and saw Chisato, but she was different.

Floating just above his back, her hair was glowing golden and her eyes were blue.

"Heavy Chain..." She started with a smile and Y/n's eyes widened.

But then, he smiled warmly with a blush when Chisato held his Demonic left hand.

"...That does freeze my bones around!"

With Chisato helping him, The two grabbed the sword and plunged it into Y/n's stomach. The sword glowed a bright blue before bursting into particles. The particles began to swirl around Y/n and he could feel power flow through him.

Balfear's eyes widened when Leohart flew straight past him at blinding speeds and into the wall.

"Leo...hart...sama."

Slowly, Balfear looked to where Y/n was and his eyes widened even further. Standing there was Y/n, but he was different. His eyes glowed an ominous red. In his left hand, he held Yamato, but the strange thing was, was that he still had his Demonic appendage.

Behind Y/n, was a translucent shadow of a Demon that floated behind. It had a sheath attached to its left arm.

From out of the dustcloud walked Leohart, seemingly unharmed. His face however was one of deadly seriousness.

"Tell me, are you a descendant of Diluc? The great warrior who fought on the frontlines during the Great War?" Leohart asked and Y/n began to blink repeatedly.

All the rage Y/n had felt started fading as he started remembering where he saw Leohart.

"I...saw you...In a portrait with a woman and a man."

Hearing Y/n's words, his eyes widened in shock.

'Woman? Liala! How does he know of Liala!' Leohart tried his best to stay calm, but he was struggling. "Speak. How do you know of that portrait."

"Answer me first. Where is Sheila?" Y/n asked with a glare.

"I have no idea what you are talking about." Leohart said with a confused tone.

Y/n's teeth ground together, but ultimately, he clicked his tongue. Just as he was about to let his guard down, a ball of black fire was sent towards him. The floating demon behind Y/n crossed its arms, mimicking Y/n's action. The explosion of the fireball blew Y/n backwards and into the wall.

"Leohart-sama, I hope you are not injured." Spoke a voice from the shadows.

"Zolgia. Why are you here?" Leohart asked and Zolgia just smirked.

"I heard there was a disturbance and was worried for your safety."

Y/n groggily stood up and he shook his head before glaring at the newcomer. He flared his aura and the entire castle began to crumble.

"Leohart-sama. Allow me to take care of this." Zolgia said and stepped forward.

Just as he was about to attack, Y/n's eyes widened when he felt a chop to his neck. He fell forward onto the ground with a thud. While losing consciousness, Y/n struggled to look at the person that stood next to him.

'L-Larz?' Y/n thought confused as to why Larz, who was wearing a mask, attacked him.

"Leohart-sama." Larz started and went on a knee with his right hand over his heart.

Y/n started blacking out and the last thing he saw was Larz preparing to unleash his magic on him.

"Y.........Y/n.........Y/n! Wake up!"

With a splash of water onto his face, Y/n's his shot open. He immediately sat up and Yamato appeared in his hands.

"Easy. Easy." Larz said holding his hands up and Y/n shook his head.

"Larz? What the hell was that?!"

"You idiot. If I hadn't intervened, they would've killed you! Now shut up and listen to what I have to say." Larz said with a glare and Y/n started calming down. "Thanks to that dumb little stunt of yours, I was able to join the Demon Lord faction. I told them that I was just a wondering Demon."

"You joined them? What for?" Y/n asked curiously but then realization hit him.

"Yeah. I'm gonna infiltrate the Demon Lord Faction and find where Naruse Mio is as well as Ruri and Haru's killer. Perhaps I can also learn where Sheila is." Said Larz with gritted teeth.

"Well, if the Demons are gonna get involved with Wilbert's Daughter, then my guess is the Heros will too."

"How do you know that?"

"Just a feeling. A strong one. Knowing them, they might send an observer or an assassin. Larz, try and find out as much as you can...I'm counting on you."

"What are you gonna be doing?" Larz asked and Y/n stood up to look at the river they were at.

"I....I'm gonna find a way to get stronger....Even stronger than before."

"....Okay. Okay. I think I might have a plan for when I find her."

Chisato stared at the night sky from her couch as she sipped a glass of wine. As she swirled the red liquid around in the glass, Y/n's face came to mind. His red hair and red eyes that she couldn't stop staring at whenever he was around. Her cheeks flushed red, maybe because of the wine or something else, but one thing was for certain...

She couldn't get rid of her rapidly beating heart whenever the boy came to mind. Suddenly, the was a knock at the door and it snapped her out of her thoughts. With a soft sigh, she walked towards the door and opened it up.

"Uhm...If you wouldn't mind me staying here one more night..." Y/n said with a flustered expression.

Chisato looked at him, her gaze lingering on him, taking in all his features the same way he did to her. With a genuine and beautiful smile, Chisato stepped aside and gestured inside.

"Stay as long as you like."

With their plan in motion, Y/n and Larz will make their move.
