Sin System: Demonic Harem After Reincarnation

Two large teleportation circles appeared on the battlefield. From one circle came the sound of snakes hissing and from the other came various grunts.

Yvonne and Jake quickly targeted the magic circles from where spatial fluctuations were intensely spreading.

The dragon girl opened her mouth and breathed a beam of hot flame. Jake opted to use [Shadow Spears].

As Nyssa and Kaine tried exiting from the teleportation circles, they had to defend the incoming attacks before they even stepped foot on the 72nd Floor.

This made Jake's side have the upper hand. At this moment, Fiona faced the Dungeon Fairy and uttered a long high-pitched shriek.

Sonic Cry!

It was another one of her Unique-grade skills. As soon as Jake heard it, he couldn't help but feel a dizzying sensation in his head even though the cry wasn't directed at him. It was as if he was listening to several jets taking off at once.

The fierce shockwaves that threatened to destabilize his footing swept away Sren.

While Fiona's attack temporarily occupied the large dungeon fairy, Jake quickly churned various thoughts in his mind. With the Fel Mistress and this werewolf joining, things might get tricky.

But at this moment, Yvonne's amber eyes shone brightly. Dragon horns, wings and tail emerged on her body and a peak 5th Circle aura dominated the area.

Jake felt a sense of inferiority to this dragon. He stopped his movements and tried kneeling, but suddenly stopped himself. Cold sweat flowed on his back as he realized Yvonne was transforming.

Sren also noticed that and tried to stop her with his strongest spell, Life Extermination. It was a powerful, and in most cases, a sure-fire curse which resulted in the target's death.

Sren hadn't planned on using it so early as he could only invoke the spell once a day, it took some of his own lifeforce to cast.

But now that things had come to this stage, he had no reason to hold back.

A dark beam shot from his hand, as if it was slicing reality itself. As Yvonne's body began enlarging, she wasn't able to cast magic to shield herself.

''Hiss…''

''Aooo…!''

Kaine and Nyssa tried to stop Jake and Fiona from protecting the transforming Crimson Dragon. Jake had the time to go and use Sphere of Darkness in front of Yvonne.

When he thought about it though, he decided not to help her. With the dragon girl's vitality, it was highly unlikely that she would die. The spell might seriously injure her, of course.

'But that means I would have a chance at corrupting her… Even if she remains unharmed, it would still be a good thing…' Jake thought as he dodged the poisonous bites of Nyssa's snakes.

Chiii!

The dungeon fairy's spell, powered by the dungeon's immense mana landed on Yvonne's scales. She was still in the middle of transforming and the dark beam spread like poison on her body.

The 5th Circle Crimson Dragon fully transformed and shook the entire 72nd floor with her roar. The Life Extermination curse targeted her soul as well as her body.

While Yvonne cried in agony and internally fought the curse's power, the dungeon fairy rapidly tried absorbing the mana he had just expended. Sren didn't have a mana core in his body and relied entirely on the dungeon core.

Finding the opportunity, Jake forcefully disengaged from Nyssa. She was repeatedly firing Rays of Petrification on him, but his Negation Aura wasn't letting her succeed.

Instead of helping Yvonne, Jake instead dashed toward the large dungeon fairy with dangerous glints in his eyes.

[Icicle Rain]

He pointed at Sren who temporarily had no way to defend himself. Sharp shards of ice fell from above and immediately began pinning the dungeon fairy to the ground.

The icicles this time were bigger and longer, Jake's skills had leveled up. This opportunistic attack dealt fatal injuries to Sren.

Especially his wings which no longer had the fairy dust. Sren furiously began chanting to counterattack the demon even though he was low on mana.

However, Jake was a few steps ahead of him. Unlike the fairy, he didn't need any incantations to cast magic. Jake began bombarding Sren with Shadow Spears.

''Daddy, he's behind you!''

Tiiing!

At the same time, he deflected the werewolf's sharp claws with his scythe. Kaine had stopped fighting with Fiona and went to interrupt the demon, who, at this rate, might just kill the dungeon master.

Suspiciously though, Nyssa didn't try fighting with the demon again. She was using less power in this battle. Although it wasn't obvious, Jake had a feeling that she could do better.

As a mature 4th Circle Gorgon, she definitely had great physical strength and speed, but she was fighting passively even with the homunculus.

Roaaarr!

''You darn pest!'' Yvonne, who was fighting the curse, let out multiple roars and swept her large wings.

While she rose up, the wind blew dust and debris on the floor. As she opened her mouth, Jake noticed a ball of rotating fire inside.

For a moment, his heart stopped at the immense power behind it. Then his mind took over and Jake abandoned attacking Sren. He instead flickered out of the way, taking Fiona with him.

A huge breath of flame roasted the air and landed on the dungeon fairy the next second. Nyssa managed to save herself in time, but Kaine couldn't.

The flame passed through his body, taking the werewolf's life and his pitiful howl away.

As a desperate measure against this full-blown 5th Circle attack, Sren created a translucent black shield out of his fairy wings.

Unfortunately, the Crimson Dragon's wrathful flame burned the shield like a paper.

Jake paid special attention to the dungeon core and saw that it was getting extremely chaotic. If this kept on, then it might really explode.

Jake's agitation increased, and he even considered helping the dark mage. But unexpectedly, Yvonne's flame died out, preventing Sren from dying.

''She's transforming back to her human form…?'' Jake muttered and suddenly noticed a severe weakening of the dragon's aura.

'The curse… it took her a lot of strength to survive that, and fire such a powerful attack… She has thoroughly exhausted herself.' He then looked at the dungeon fairy who was in a half-dead state.

Jake realized that this was the perfect opportunity to corrupt them both!
