Eldest sister Stheno and second sister Euryale were both pure goddesses, the embodied ideals of male longing.
The price of their immortality was becoming the most delicate beings in the world.
They were goddesses who could not survive without relying on others.
Yet they still chose to raise you.
As both goddesses and family, they were irreplaceably important to you.
Though this was merely a simple life simulation, Moran possessed every detailed memory.
To him, it was no different from a second life.
Precisely because he knew how fragile his two sisters were, he could not easily lose his temper with them.
Even though they lacked even the slightest ability to survive on their own.
They had still chosen to raise him.
Aside from her mischievous fondness for teasing others, Stheno had never done anything particularly excessive. On the contrary, she had painstakingly raised Moran from infancy.
"Eldest Sister, I think... I'm late..."
Medusa timidly hid behind a stone pillar.
Her voice was as faint as a mosquito's buzz, yet Stheno still caught it clearly.
"Medusa, didn't I order you to guard the treasure chest with that Great Serpent? You can't even manage something so trivial, and you dared disobey your sister's orders. It seems I'll have to punish you properly tonight..."
"Guh! I'm prepared!"
"Fine, then. To let me see your resolve, Medusa, defeat Moran, the hero."
Stheno's beautiful eyes were full of amusement.
Sure enough, she saw the conflicted look in Medusa's eyes.
Ever since Moran had arrived on The Invisible Island.
The sisters' target for teasing was no longer just Medusa; Moran had been added to the list.
Perhaps because they empathized with each other.
Medusa and Moran had a very good relationship.
So good that even Stheno was a little jealous.
"I'm sorry, Moran. Eldest Sister's orders are absolute. I have no choice..."
"Well, I'm used to it by now."
Moran shrugged, gripped his sword, and assumed a stance.
After all, they had such a willful eldest sister, and they were each other's only family on this island.
You engaged Medusa in an intense battle.
Stheno played both director and actress. While the two of you fought, she chose to side with you.
Unable to defy her eldest sister, Medusa naturally lost.
Perhaps the outcome of your battle never mattered at all. From the very beginning, Stheno had merely wanted to see Medusa's conflicted expression.
"You couldn't even carry out the order to fight with all your strength? A foolish little sister really is a foolish little sister. It seems you still need a proper punishment."
"Eldest Sister... I'm sorry..."
Medusa lowered her head, deeply ashamed.
Stheno smiled at the sight.
In truth, no matter what Medusa did, she could not escape. Stheno would always find some excuse to bully her.
"Hehe, Medusa is quite bold, isn't she? Then I suppose I have no choice but to join in too. I'll help deliver the punishment."
Another person entered the scene.
If Stheno was the embodiment of nobility and allure, then she was an idol-like girl who combined purity and cuteness.
This was the middle sister of the three, Euryale.
Medusa could only accept her fate with a sorrowful expression now.
"What is this...?"
"Moran, these are the flowers and herbs left over after I finished decorating. You may tearfully kneel and accept them, then thank me."
Moran caught the flowers and herbs Euryale tossed over.
At a glance, he recognized the medicinal herbs mixed within them.
"It's fine if you give some to Medusa too. They're nothing but excess weeds to me. I unknowingly gathered too much along the way, so you can take them off my hands as garbage."
"Mm... Second Sister... thank you so much...!"
Seeing that she would get some of the herbs too.
Medusa hurriedly voiced her thanks after accepting them.
Euryale nodded, clearly pleased.
"It is normally impossible for a goddess to give things to others unilaterally, you know. Yes, this is merely garbage disposal, so don't get carried away."
"..."
Moran did not know whether he should point it out.
It was obvious that Euryale had prepared these herbs especially.
She was worried that her younger brother and sister might get hurt.
Although the two sisters seemed very sharp-tongued on the surface, they actually cared more about Moran and Medusa than anyone else.
Both Stheno and Euryale were like that.
Toward anyone they did not deem worthy of affection, or simply looked down on, the two women were so cold that even Cerberus would tremble.
It was precisely because they loved them more than anyone else.
That they took such delight in teasing them.
To Stheno, this was the best proof of how much she cherished her younger brother and sister.
Loving someone and enjoying teasing them.
In fact, those two things did not conflict much.
"Moran, I permit it. You may now pour out your gratitude to me to your heart's content~!"
"Wow... thank you very much... Sister Euryale..."
"Mmph... That was far too perfunctory! There wasn't any feeling in it! Where is the love and devotion a younger brother should have for his sister!?
Don't run! Moran! Stop right there!"
Euryale cried out cutely, clenching her little fists.
Before she could say anything else to complain, Moran had already slipped away.
That was Moran's daily life on The Invisible Island.
Drink This Sweet Blood
You were awkwardly cherished by Stheno and Euryale, and together with Medusa, you fought magical beasts and invading heroes.
Though it was a mundane daily life as bland as plain rice.
You still found a happiness and joy within it that you had never experienced as a Magus.
If possible, you wanted to protect them forever.
The Simulator's narration described Moran's inner journey.
He knew that beautiful times could not last forever.
As usual, you prepared an exquisite dinner for the three sisters, as you had done for twelve years, while night quietly descended.
"Euryale and Stheno are going to punish Medusa tonight."
Thinking of the pitiful Medusa being bullied by her two sisters, your choice as her younger brother was—
One, help Medusa.
Two, since the two sisters would not hurt Medusa anyway, obediently prepare dinner for them as you always had.
Two options suddenly appeared before him.
Moran's perspective shifted from first person to a god's-eye view.
The life simulation system could not help but make him laugh. The sudden options reminded him of the beginnings of Type-Moon.
Whether Tsukihime or Fate.
They had both started as fantasy games with different choices and dozens of possible endings.
This Simulator was probably the same genre.
"I choose option one."
Moran chose according to his first instinct.
As an old Type-Moon fan who had long been familiar with the formula, he trusted his intuition. More importantly, he could not simply stand by and ignore Medusa.
As the saying went, when young, one did not know Rider's worth.
And mistakenly treated Saber as treasure.
Moran remembered that little rhyme perfectly from before his transmigration. Now, he had completely taken Medusa's side.
Naturally, he would choose to help Medusa.
Over countless past nights, he had seen that lonely, desolate figure bathed in moonlight.
She had always kept the young Moran company.
Of course Moran wanted to care for and protect her.
You set down the ingredients. Rather than finishing dinner first, you wanted to rescue Medusa from your two sisters.
You followed their presence to search for them.
However, while searching, you caught a strange scent of blood. It was Medusa's blood.
You burst forward at full speed toward the source of the blood scent.
There, you saw—
Night seemed frozen.
Everything had come to a halt.
The moon hid behind dark clouds as if ashamed to witness this scene, while the soft lights in the forest resembled paint splashed across a picture.
You glimpsed a vivid scene amid the trees.
"Hah... Eldest Sister... Moran..."
Medusa exhaled heavily, her cheeks slightly flushed.
Her violet eyes were misted with moisture.
The one who had left Medusa in such a state was her eldest sister, Stheno. Her sharp canine teeth had pierced Medusa's fair, delicate skin.
Crimson blood trickled down her neck.
"This is punishment, punishment for defying your sister. You are not allowed any right to refuse."
An enchanting smile rested on Stheno's face.
She cast her gaze beyond the forest.
Noticing a fourth person entering this domain, her smile seemed to gain another trace of pleasure.
"Moran, you came too. Perfect. Since this is punishment, no one can be left out. Come here as well."
Stheno licked the bead of blood remaining on her crimson lips.
Before you continue
