Character details

The eldest of the three Gorgon sisters in Greek mythology.

The epitome of what men long for, the perfect "idol."

A goddess that was born as the "perfect woman."

A beautiful woman as if elegance and refinement were put into human form.

Euryale and Medusa are her younger sisters.

Profile 1

Height/Weight: 134cm, 30kg?

Origin: Greek Mythology

Region: Europe

Alignment: Chaotic-Good

Sub-Attribute: Heaven

Gender: Female

About the weight, supposedly "the same as myself (Euryale)."

Profile 2

Any man would praise her elegance upon looking at her.

But if you look deeper, she has an extremely stubborn personality.

To those she doesn't care about, she is extremely cold.

So much so that even the watchdog of the underworld (Tartaros) would shiver.

Profile 3

About my younger sister (Medusa), I do end

up bullying her with my other self (Euryale) at every opportunity, but in the end I do love her.

...I love her from the bottom of my heart. Even after death.

Profile 4

Core of the Goddess: EX

A unique skill that demonstrates she was the perfect goddess from birth. A combination skill that includes Divinity.

Repels all interference to the psyche, and stops any physical growth.

Also, no matter how many calories she ingests, her body will never change.

Profile 5

『Smile of the Stheno』

Rank: B

NP Type: Anti-Personnel

Smile of the Goddess.

An ascended version of the goddess' charm that enchants heroes.

A melancholy gaze that turns into a blade, and a sweet whisper that turns into poison.

Additional profile

She has no wish to be granted by the Holy Grail.

If forced to come up with something, it would be for "the three sisters to live together forever," but she knows that is impossible.

She only thinks about one thing regarding her seemingly impossible summon

...that is, whether or not she can enjoy herself.

Bond Level 1
I am a goddess. I am a phenomenon born of the desire to captivate brave men. It's one thing to take part, but do well to make sure you don't get stuck, yes?
Bond Level 2
I don't have any particular interest in mankind or the future. I just wanted to live on that island with "us."
Bond Level 3
My role is to be loved. I am used to being left scattered. But do not mistake me, Master. We have never loved your kind, not even once.
Bond Level 4
The three of us always desired to live together on an unimaginable island alone... But I suppose we could take you, too. Though we can't have any humans. I guess you would have to become an ant or something first.
Bond Level 5
...Hmph. How can you still not have figured it out? Ok, fine. You win. I love you, Master. Oh no, no no, just kidding.
Conversation 1
You're going to save the world, yes? Then we best not wait around here.
Conversation 2
Something the matter? No, what is it, Master?
Conversation 3
Being the one to serve... It feels so strange. What an odd experience.
Likes
What do I like? Yes, let's see. Euryale and Medusa, of course, but we are always kept so far apart.
Dislikes
What do I hate? When lowly humans try to act like they know me... No, just kidding of course!
About the Holy Grail
The Holy Grail. If I get my hands on that... Hehe, it's nothing. Oh I am such a fool...
Conversation 4
Hehe... Whatever will I do with you? What are you trying to do, getting close to a goddess like this...
Conversation 5
What is it? Do I mesmerize you so?
Conversation 6
Hehe, you're a cute one, Master.
Conversation 7
Are you having fun, Master?
Conversation 8
Euryale. You are very beautiful today, as always. Really. Even more so than yesterday... Teehee. Maybe it's just my imagination. Maybe...
Conversation 9
Medusa, come over here. Don't make me say it again, Medusa.
Conversation 10
My little, little Medusa. Don't be so scared. Nobody is here to tease you. Come on now, show me more of that face of yours.
Conversation 11
The fact that your True Name is Gorgon isn't your fault? Heh. Not my problem. You are Medusa. Rather, you are ALSO Medusa. Isn't that right?
Conversation 12
Bad Asterios. Stop it. Don't try to hoist me up on your shoulders. I'm not Euryale. Huh? You know? Sometimes you want to be with Stheno? ...Teehee. You're such a softie at heart.
Conversation 13
Heracles... I guess when we talk about what a real hero or valorous sort is, he's bound to come up. It's a shame he's lost his sense of reason.
Conversation 14
Lord Odysseus. I wonder what would have happened to us if he had wandered onto our island...?
Conversation 15
I see, so you're sister Servants too? A pleasure to meet you.
During an Event
Sounds like something is going on. You're going to head out and see, right?

Happy birthday. Oh yes, your birth is definitely cause for celebration. Hehehe.
