Marina Akizuki was in the middle of a deep sleep when a blurry figure appeared in her dream.
"Wake up, Marina. Your sister is in danger."
The voice was so strange and out of place that it left the girl feeling confused.
"Who are you? What are you talking about? My sister's fine. Why would she be in danger?"
The figure, Andrew, answered casually.
"I'm just a demon, passing through the human world for a bit of fun. Your new stepfather has just broken into your sister's room, and that pervert is about to lay his hands on her."
"If you want to save her, call my name. Remember, it's Andrew."
At that, Marina woke with a start.
Without a second thought for whether the dream was real, she scrambled out of bed, slipped on her sandals, and rushed out of her room.
She saw her stepfather, Kōyō Akizuki, enter her sister's room. Too stunned to think, she hurried over to the door and peered inside, where she saw him stripped down to his underwear. Her sister, Airi Akizuki, sat on the floor, paralyzed and teary-eyed, looking so helpless.
Airi's cheeks were flushed, a deep, unnatural red.
"Waaah! Big sister, save Airi! This scumbag wants to… wants to do that kind of thing to Airi… I told you and Mom he was bad news, but you didn't believe me!"
"Shut up, Airi!" Kōyō cursed, quickly pulling out a spray can and aiming it at Marina, who was too slow to dodge.
Suddenly, Marina fell victim to the same fate as her sister. Airi, seeing how slow her sister was, started crying even harder.
Even Andrew, who had been in control of the situation, was speechless. He'd just warned Marina, and she still got hit.
The heroines in these fanfics really are weak, he thought.
Kōyō stared at the panicking Marina, who was now sitting on the floor, unable to move, her face flushed red. He couldn't help but laugh.
"Marina, since you're here, why don't you join us?"
"But I think I'll discipline the naughty little Airi first."
Kōyō stepped toward Airi, reaching his hand out to her.
In her panic, Marina suddenly remembered the demon from her dream. As if by magic, she screamed out his name.
"Andrew! Mr. Demon, please save me and Airi!"
"As you wish!"
A flash of purple light exploded. Before Kōyō could react, he was thrown back by an unseen force, hitting the wall with a sickening thud.
A burst of flames instantly consumed him.
Kōyō had served his purpose of demonstrating his evil, and Andrew had fulfilled his goal of playing the handsome demon saving the day. He had no reason to keep the man around any longer. A piece of trash like Kōyō only existed in Andrew's eyes to be a tool to highlight his own glorious demonic form.
Marina and Airi stared, dumbfounded, at Andrew's appearance. They took in his handsome, dashing face and the charmingly wicked smirk playing on his lips.
The girls' already flushed cheeks became even redder.
"Ah… big sister… who is he? He just appeared like that… well, whatever, he's so hot… hurry, Airi can't take this anymore."
Before Marina could even react, Airi used all her strength to wrap her arms around Andrew's legs, her eyes looking at him with a seductive gaze.
Calmly, Andrew wrapped his arms around the two girls and shut the door.
He was a demon who had appeared to grant Marina's wish.
He couldn't forget the power of that wish. Through his guidance, he had proven that he could personally orchestrate events, and he and Marina had reached a verbal agreement.
Now it was time to collect his payment.
"Waaah… big sister… Airi… Airi feels so bad. Please… that handsome big brother, please hug Airi."
That drug Kōyō used was strange. It amplified a girl's desires, and it was probably because of this drug that he became such an evil soul. If it were to become widespread, the girls of this world would be in serious trouble.
"Airi… how can a girl say such shameless things?"
Marina's face was flushed red as she tried to scold her sister, but her own body was starting to feel strange. She suddenly couldn't say a word.
Andrew wasn't in a hurry. He just calmly held the two girls.
"I am a demon, Ms. Marina. I appeared for you and have solved your crisis. Now it's time to collect my payment."
"Demons don't do business at a loss, you know. And anything else, well, that'll cost extra."
Marina's eyes widened, and she looked at him with a teary gaze. "How can you say that? I thought you were a good person."
"I told you from the start I'm a demon. So, Marina, and you, Ms. Airi. What would you like to get from me?"
Andrew's gentle smile charmed both girls.
Even though he was a demon, he was still much better than the scumbag who had tried to hurt his daughters.
As the drug continued to take effect, Airi was the first to give in. She burrowed into Andrew's arms, clumsily pulling at his clothes.
...
"Anything's fine, Master. Airi will agree to whatever you want… ugh, it hurts… please, help Airi… okay?"
Andrew's expression softened, but his eyes shifted to Marina, who had lowered her head, cheeks burning bright red.
"P-please, my sister, Marina… save me… good sister… please…"
"Airi… don't worry. Your sister will save you…"
The two beautiful sisters, bound by a deep affection for each other, finally gave in to the desire buried in their hearts, unable to resist the devil's cunning temptation.
Andrew accepted their answer. In that instant, the contract was sealed.
New Familiars: +2
"Very well. As you wished, I've heard your desires loud and clear."
Now it was time to fulfill them.
A devil's word was binding. Once a promise was made, it had to be carried out.
And so, like a dream made real, the scene unfolded naturally before them.
Marina Akizuki felt as though she were drifting inside a dream. Andrew's gentle, handsome presence, his practiced movements… guiding the innocent girl step by step.
Compared to her shy sister, though, Airi was far less reserved—almost eager.
They still have a lot to learn, Andrew mused. The Akizuki sisters have only just begun their lessons.
After giving them both some "guidance," he left behind the seed of his demonic power, then dissolved into magical essence and departed.
As for how things would unfold after the disappearance of Koyo Akizuki… that could wait until tomorrow.
Back in his own room, Andrew took a bath, then slid into bed. He wrapped his arms tenderly around Mahiru Shiina, breathing in her soft scent as he drifted peacefully into sleep.
He hadn't even had time to check what powers his two new familiars had granted him.
The Next Morning
When Andrew woke, he immediately noticed his magic had grown stronger again. His status screen had changed.
[Demon Growth Panel]
Player: Andrew (Sole Contracted Demon)
Current Familiars: Mahiru Shiina, Asada Shino, Haruno Yukinoshita, Yukino Yukinoshita (bond incomplete, no ability granted), Airi Akizuki, Marina Akizuki.
Demonic Abilities:
Super Regeneration
Guaranteed Hit (attacks never miss)
Damage Absorption & Transfer
Damage Stacking
Dual-Hand Casting
Demonic Authorities:
Contract (Innate Authority; once a soul is bound, the contract is eternal and unbreakable)
Flames of Judgment (power increases with the number of familiars)
Lord of Magic (chance to comprehend new spells as familiar count increases)
Reading through the list, Andrew gained a new understanding of his own power.
So Yukinoshita's little sister was already counted among his familiars. It made sense—during their first proper meeting, she'd said she would do anything for her sister. That was as good as acknowledging she belonged to him.
But since they hadn't bonded deeply yet, unlike Haruno, Shino, or Mahiru, he hadn't unlocked her gift.
Airi, however, had granted him Damage Stacking.
Marina had given him Dual-Hand Casting.
Dual-Hand Casting meant he could use two completely different spells at once—an extremely valuable ability. And it didn't just apply to magic. Once he acquired other powers, he'd be able to trigger two skills simultaneously.
Imagine unleashing two ultimates at once.
Then there were the Authorities—innate abilities tied directly to his soul. The more familiars he contracted, the stronger they would evolve, even branching into entirely new forms.
One gives birth to two, two to three, and three to countless possibilities.
His Contract Authority held limitless potential.
Meanwhile, the Lord of Magic Authority gave him sudden flashes of insight, allowing him to comprehend new spells out of nowhere. For example, that teleportation spell—Magic Shift—that let him instantly appear by a familiar's side. He hadn't studied it. One moment it was just an idea, the next it became a skill.
These revelations most often came when he sealed a new contract.
In short, if he wanted to keep growing stronger, he had to continue making pacts.
And the more beautiful girls he brought under his contract, the better.
