7Character details
Astraea chose the most fitting vessel to possess for the goddess of justice and balance. A person who was born to stand above others...
If you believe that premise holds true, she certainly fits the bill. Having accepted that her duty is to wield justice as her Authority, she will never go out of control by claiming it to be her right.
...However, despite her virtuous standard, whenever she comes across anything rare or precious, she has a tendency to think it of utmost importance that it be protected. In other words, she is the most elegant (cunning hyena) even when she is from the heavens.
Profile 1
Height/Weight: 160cm, 49kg
Origin: Greek Mythology
Region: Greece
Alignment: Lawful-Good
Sub-Attribute: Heaven
Gender: Female
Rather than the original Astraea, aspects of Lady Justice from later ages are more prominent in this manifestation.
Profile 2
She originates from one of the three Horae Sisters in Greek mythology and is said to have been a daughter of Zeus and Themis, but there are few accounts of this to be found in Greek myth. Legend has it that during the Iron Age, while many gods left Earth as evil ran rampant, she was one of the few who stayed behind until the very end and tirelessly appealed to humanity's sense of justice. The story of her scales later becoming Libra and she herself becoming Virgo garner only brief mention. However, in later ages, she and her mother Themis (with whom she is sometimes conflated), and Justitia from Roman mythology were given a different name and attendant significance. Namely, Lady Justice, or the goddess of justice. She is often seen depicted in statue form as a lady wielding a sword and scales and frequently appears in front of courthouses and law offices.
Profile 3
Originally, her functional aspects were more pronounced, and she was a good deal sterner and more uncompromising. However, her vessel's influence has softened her and now she tries to guide humanity personally. The same influence can be attributed to her insistence upon hand-to-hand combat. She may wield a sword and scales, but in a fight, she will simply toss them away to engage in techniques most often seen in professional wrestling, which she sees as her true justice. Whether this was unfortunate or simply inevitable when her vessel was chosen is not clear, but the fact of the matter is that the girl's style matched Astraea's unparalleled toughness as a Divine Spirit of judgment, ultimately becoming the most prominent Servant for unarmed combat.
Profile 4
Blessing of the Scale: A+
A skill based on the Divine Spirit Astraea's Authority. This skill deploys an impenetrable defense mechanism against targets awaiting judgment, as the scales that symbolize Astraea are embedded within her body. However, her vessel's wishes have transformed it into a skill intended for hand-to-hand combat. In other words, the professional wrestler will never fall.
Star's Judgment: A
Under the Authority of the stars, all targets who are to be tried, humans on Earth and even Divine Spirits, are forced to accept their judgment.
Profile 5
『Custos Morum』
Rank: A+
NP Type: Anti-Crime
Range: 1-100
Maximum Targets: 100
The Time of Judgment Is Now. State Thy Name.
The scales that are her original Authority materialize and the target is put on trial and sent to the court of the stars. The Noble Phantasm then rains down stardust in accordance to the weight of the target's crime. Unlike Ishtar, who throws the concept of Venus with all her might, Astraea hurls countless stars from the night sky without restraint.
Additional profile
"Justice by the stars means...a suplex!"
As she has ever been the embodiment of justice for humanity, she will not hesitate to assist in humanity's restoration. Should she have a Master who still has room to grow, she is all the more enthusiastic, believing that it is her duty to guide them. Her vessel's personality also factors into this, and so the Servant is quite stern with regards to her Master's demeanor. If her Master is vulgar, she will not hold back in coaching them (through physical means, including drop-kicks). For Masters who wish to stand alongside her, it would be best not to neglect their training.

- Bond Level 1
- Be cautious so as not to be judged by my scales, Master. If the weight of your sins is exposed, I will have no choice but to take you down.
- Bond Level 2
- I don't know how to express it, but you are certainly exceptional, Master. You are a mediocre mage at best, but you have traveled the world. I'm surprised your soul is still intact. Yes... I am finding you more and more intriguing.
- Bond Level 3
- I'm starting to understand. My balancing scales are meant to measure others, and I see that your mediocrity tends to make others worry over you. Haha... You look so puzzled... All that matters is that you never forget who you are. Nothing else.
- Bond Level 4
- Ahhh! I told you not to make me worry! I am a goddess of judgment. Should the scales tip, I will need to make a ruling, even for you. Well, uh...this is the first time I've wanted to not judge someone.
- Bond Level 5
- I give up! I submit! My scales will not change, but I will side with you. This is not a judgment... It's my own choice. Until the day your journey ends...that's right, I'm not going to leave your side even if you try prying me away!
- Conversation 1
- Let's head out to investigate. My scales are itching to go!
- Conversation 2
- That's right. It is my prerogative to stand above others. But for the time being, I shall entrust my fate to you. The stars whisper the same.
- Conversation 3
- Master and Servant relationship? You do whatever you want. I'll do what I want to do, too.
- Likes
- What I like? Let's see... What would you think if I said I like taking what others see as precious? That's not fitting for a goddess of justice, you say? Haha... I'll have you know that justice can be harsher than evil at times.
- Dislikes
- I dislike anything that lacks pride. Since there's no inherent meaning to life or death, pride is the very thing that gives us meaning.
- About the Holy Grail
- If you ask me what I would wish for on the Holy Grail, that would be difficult to answer. After all, I already have everything I've ever wanted. But if I had to choose, it would be something that could not be measured on my scales... Haha, Master, would you be able to give that to me one day?
- Conversation 4
- I can't believe she takes joy in collecting those ugly old gemstones! Well, one of these days, I will have to show her who is truly number one!
- Conversation 5
- Oh my, that goddess has a summer outfit!? Then I have no choice! Hurry up and procure a swimsuit for me, Master!
- Conversation 6
- Shero... Don't mind me, that name just popped out. I'm sure that's not his name. I actually don't know why it even popped in my head.
- Conversation 7
- He must be the end result of some ideal or other. I bet he intended to burn himself to ash. Yet... Argh, this is still getting on my nerves! I'm going to give him an earful!
- Conversation 8
- That mage is an incessant nag and busybody. The only thing I'll give him is that he's a good teacher!
- Conversation 9
- I can't believe Quetzalcoatl is here too! And she's a luchadora on top of that!? I want a wrestling match with her!!!
- Conversation 10
- It's wonderful to see her fight so bravely...but don't you think she's too young? Well with humanity so unstable, her pure innocence may be of help too, but that's what makes it so heartbreaking...
- Conversation 11
- I don't know why, but I can't help but look at her. Maybe I'll have her accompany me.
- Conversation 12
- Haha. So that one girl who wields the sacred lance is here too. If the mood takes me, I'd like to take a stroll through the London we Rayshifted to.
- During an Event
- It looks like something is going on! Come on! The world is waiting for my judgment!
- Birthday
- It's your birthday, you say? Well, I feel like I should offer my blessing on the day of your birth. In fact, I might even consider putting my scales down...
