Demon Lord: Erotic Adventure in Another World

Ryuji stood with his axe over his shoulder, taking a deep breath. He glanced towards the five girls opposite him while they prepared themselves.

Yumiko's figure transformed into her demon form, her gauntlets shimmering as she lowered her hips to fight. Erika stood ahead of the group with two swords in her hands.

'Their group makeup is quite amazing from this side. Yumiko, the damage dealer and tank, Erika to support her, with Ciela's magic arrows supported by the magic of Liana and Sariel. Should they be in danger Yumiko can use group wide healing spells even while fighting.'

"Ryuji~ are you sure you wish to fight all of us at full strength?" Yumiko asked while her beautiful white hair flowed in the fierce breeze. Nine lovely tails tapping the floor with loud thumps on the ground.

"I'll fight with everything I have Ryu!"

"Master, Sariel wants to sleep together~ she will win, ehehe."

"Darling, I will show you my growth as a witch!"

"My Dear Husband, let me show you the power of my magic arrows!"

"My beloved women, you should quickly transform. I am not going to go easy on you during training."

The next moment, Ryuji's body grew over a foot taller, two black horns growing from his thick blonde hair that turned snow white and grew down his back. Then his mouth opened wide, long fangs replacing his teeth as he roared into the sky, his eyes turning jet black with sapphire blue orbs in the centre with slit pupils as black markings covered his entire body.

"!!"

"Erika, he's coming follow me!"

"Understood, Yumiko!"

Yumiko's body rushed out while Ryuji's transformation was reaching the pinnacle; his long red wings formed of blood unfurling with a sonic boom, creating tremors in the air around him as Ryuji's eyes snapped to the two women approaching.

"Liana assist me in covering them!" [Arcane Archery: Blaze Shot]

A swirl of flames spiralled around her fingers before forming an orange arrow with a round tip that crackled and seemed unstable.

"I'm going!" [Wave of Shadows]

The four scarlet arms behind the demon form Liana her black eyes and crimson iris shimmering as all four arms flickered with a black orb of darkness before she flung them forward, creating a huge tidal force of shadow.

This shadow masked the approach of Erika, Yumiko and Ciela's Blaze Shot!

'Hmmm? What a clever tactic.'

"Gruuuu!"

As Ryuji stepped forward, the four shadows from behind the wave of shadows exploded towards him as a second blaze shot pierced the fading veil of shadows.

'Good! You can cast it consecutively!'

Ryuji's figure blurred as he used his wings and his left leg to push off the ground, avoiding the two orbs of darkness, his wings flapping once as he reached the two girls behind the blaze shot. Ryuji's axe sliced across the air, forcing Erika's swords to block the blow with all her strength.

"Urgh!"

"Erika!"

Yumiko's voice yelled as the impact caused the beautiful knight to shoot backwards, her body twirling in the air from the sheer impact of Ryuji's blow.

"Leave it to me, Ehehe~ Yah!" [Wall of Clouds]

Sariel cast an illusory magic that caught Erika's fall, lowering the damage and impact significantly as she fell to the ground, covered in dirt and bruises.

'An area spell to stop her fall? Good work, Sariel.'

"Yumiko, get out of the way!"

"Do not worry about me, Ciela. Hah."

Instantly, Yumiko began to attack using the martial arts of his mother, the Kuzuha ryu martial arts style. Her attacks were quick and sharp, the air seeming to crack and tear around her as Ryuji used his wings to deflect her blows.

"Yah!"

A flurry of blows from Yumiko forced Ryuji to defend himself from her strikes, each of them being so powerful he couldn't help but smile and let out a burst of laughter. Although far from his mother's mastery, he felt a sense of delight and dropped his axe to perform the male version of Kuzuha ryu style combat.

"You have improved well, come face me, Yumiko."

Although it seemed Yumiko was his focus, his tail began to cast random magical spells aimed at the others to keep them occupied. The entire time, his wings were constantly in used to defend himself against the magical attacks of Sariel and Liana.

"Ehehe, I'm going to win~"

"Don't think you can distract me, darling."

"Ryuji, let's fight!"

"This is a great day, Yumiko."

"Ryuji."

While they fought, a small smile appeared on the faces of the group as the atmosphere became livelier and more intense as Ciela launched magic arrow after arrow, while Liana tossed all her mana into spells in order to slow or damage him. The biggest threat was the basic arrows of Ciela, which were the hardest to defend against.

'Ciela's arrows are the most dangerous as they are fast, hard to track and have a powerful penetrating force when they hit. She can also fire them consecutively, but with Sariel's support, I am struggling to deflect them.'

Yumiko's fist caught him off guard while he deflected an arrow from Ciela, her left hook sending his balance off as she followed up with a flurry of kicks, forcing him to take to the air, where Sariel ambushed him with a series of ice lances and a fog spell.

Ryuji flew backwards, a grin on his face as the five women chased him down. He was enjoying this battle, as the more he fought, the more he felt the difference in their training.

The moment he landed, Erika returned to the battle as he blocked her blade with his right arm, then smashed her abdomen with a brutal sidekick, using the momentum to catch Yumiko's punches with his left forearm.

"Hah!"

"Yah!"

"You're not getting away."

"Darling, look this way."

"Hehe, Sariel is winning!"

"My dear husband, you are not going anywhere!"

As the fight progressed, the group continued to improve as a whole. However, Ryuji noticed the team was exhausted, their breathing heavy, and sweat poured down Yumiko and Erika's faces. He noticed that Ciela's fingers were trembling, each shot slower and less accurate after a hundred arrows penetrated the wall behind him.

"You have all improved, but you are still lacking in stamina."

He then pointed his palm towards the girls, his left-wing knocking Yumiko and Erika into the distance along with the others, causing them to fall as his lips curled into a brilliant smile. [Flare Burst]

A massive wave of flames poured from his palm, the heat so intense the five girls had to create a wall of water to stop it. The steam from the flames caused the surrounding air to become wet and muggy. However, the next moment, the fire began to condense before it exploded.

"Eh?"

"Ah!?"

"Run!"

"Avoid it!"

The women watched the explosion with anxious eyes, the blast of the explosion sending a shockwave towards them. There was nothing they could do. All of them were using their mana to support Yumiko's water wall, which was all that protected them.

The moment the shockwave reached the water wall, it exploded and sent the five girls flying, their bodies tumbling along the ground like leaves in the wind.

[Muddy Zone]

Ryuji's spell caused the ground to become softer, their bodies slowed from the soft, wet mud as they all became filthy but didn't suffer any immense wounds.

He sighed as the five girls collapsed on the ground, their breaths deep and heavy.

"You all did amazing, I am proud of you all."

[Heated Rain]

His palms then cast warm, soothing water that healed and cleaned their bodies of dirt. While approaching them, his transformation slowly faded, his face calm without sweat or signs of exhaustion.

"Ryuji... I want to sleep... you're too strong."

"Ryu, will I ever reach your strength?"

"Ehehe~ Master did Sariel do well?"

"Phew... darling, you almost killed your wife, what will you do to make it up to me?"

"Husband I think my fingers need treatment, they won't stop trembling."

As he listened to their complaints, Ryuji couldn't help but break out into laughter as he looked at the five women who made their way into his heart.

"Well, you all performed well. However, I did promise, so the one joining me tonight is..."

Meanwhile, from the upper tower of Alan's mansion, a beautiful woman with black hair watched the training match with a focused gaze.

Alice's eyes focused on Yumiko and Ryuji because the Martial art they both used was identical to the one she gained in a unique skill at fourteen.

"Why do I feel so irritated?"

Her hands grasped the stone railing, almost crushing the rocks to dust as she felt a strange sense of confusion. It was identical to the one she awoke as a special, unique skill when she turned fourteen.

'What is this feeling?'

Her eyes locked onto the white-haired demon lord, his every movement causing her heart to race and her body to shiver with excitement.

"Are you feeling unwell, sister?" Alan's voice came from the open balcony as Alice turned to face him with the usual kind smile and face. However, he could see the red on her cheeks and the strange fire in her eyes.

"No, Alan. I was just looking at the battle between the future demon king and his women."

Alan's eyes looked down towards the training grounds below, his eyes focusing on Ryuji's powerful aura. He also became shocked at the sheer difference in strength from a few days ago.

"Wow... he's growing stronger faster than I imagined."

"Do not underestimate the demon lord, Alan. I believe the day he surpasses you isn't that far away, months at most, yet you call him your friend?"

Alice's voice was calm and quiet, but Alan could tell her words carried a serious intent.

"Yes, sister. Ryuji is my friend, and I trust him. When I see him, I can see a kindred spirit in him, someone I could never betray. He will not betray me, I will bet my life on that too."

Alan's serious face caused his sister to gasp before she looked down, covering her face before she began to laugh, her soft giggles causing Alan to look at her with a frown.

"What is it, sister?"

"Nothing, it's nothing. I just thought it was funny you would say that, when you don't even realise how that man makes your big sister feel."

"!!!"

Alan's eyes widened as his mouth dropped. The thought of his beautiful big sister and Ryuji sent his mind reeling in shock and despair.

"No way!"

"Alan, close your mouth. It is not what you think, disgusting boy."

"Thank god."

"Anyway, the one thing I wanted to talk to you about was the demon lord. Did you invite him to the family meeting this Sunday?"

"I did, why do you ask?"

"I want to speak with him, in private."

"NO!"

"Alan, you cannot tell me no. Or I will climb into his bed tonight and let him take my virtue."

"No, no, no, no, no, no, no, no."

"Then you will arrange a private meeting."

"Why the hell does my sister want a private meeting with him!? Please... He already took Liana!"

"Tsk, as if he could force me to do something I don't want. Even in that form, I could shatter his entire body before he inserted that weapon inside me."

"Sister, no."

"I am going to rest. See you later, Alan."

"Yes... Big sister, good night."

Alan watched his sister leave, his eyes hollow and his mind blank. The image of his sister and Ryuji causes infinite emotional damage.

"Let's spend the night in Akari's room again... Only she can soothe this pain in my heart."
