Unlock Description Translation
Default ラスベガスに現れた謎のサーヴァント。


A mysterious servant that appeared in Las Vegas.

Their true identity is masked behind mystery, but we do know that she is a first class ballet dancer, an artistic goddess, and above all else this time she is showing us her talent as a figure skater. The water and penguin servant.

Of the 5 major casinos in Las Vegas, she is the owner of the Heavenly Water Palace. At the casino, slots would be considered to be the main attraction. However, there's a rumor that gusts of wind appear out of nowhere and the slot machines spinning at a wicked speed.

The whereabouts of The Heavenly Water Palace’s customers(servants) that were left on the side of the street without a penny to their name, are left unknown to this day. We can only speculate that they were trapped by Lambda and turned into experience points…

Bond 1 身長/体重:160cm・33kg

属性:秩序・善   性別:女性



Height/Weight: 160cm/33kg

Source: Fate/EXTRA CCC
Origin: SE.RA.PH
Alignment: Lawful Good
Gender: Female
Her height has changed because of her heels coming off.

Rider: C

Talented as a rider. As a result of becoming a lancer the skill has appropriately deranked.

Goddess’ Essence: C

A skill that reflects how she became a complete goddess while being born. Due to her main essence being changed from that of Sarasvati to Leviathan, the essence has been ranked down.

Bond 2 水上のプリマドンナ、兼、カリスマフィギュアスケーター。さまざまな波を繰り出す海の女王を名乗る。


A primadonna on the water and a charismatic figure skater. Riding the waves of the ocean, she refers to herself as the Queen of the Seas.

Ready to fight at a moments notice and without mercy. A queen that enjoys tormenting others as her pastime. She loves the structural beauty of things and will not forgive anything ugly that opposes what she believes to be perfection. As she is a perfect existence, she is able to do anything by her own power which she prides herself upon. From this she holds herself highly...... well, that’s her typical self, but this time she comes as a professional figure skater to pump up the audience and bring them a good time so she’s holding back on the bullying.. for the most part.

With that being said, the core of her that is “Herself as a standard for beauty, her beauty itself is absolute in this world.” hasn’t really changed... No matter how beautiful or popular the other Swimsuit Swordmasters are she will brush it off gracefully “Oh, is that so? But at the end of the day I’m obviously the most beautiful aren’t I?”

Bond 3 正体を隠しているのはスタァだから。プライベートを明かさないのは、ひとえに熱心なファンへの温情であり、ご褒美である。



A star doesn't reveal their true self. As for her private life, she does not divulge any details for simply one reason, it's out of her own thoughtfulness that she does this as a reward for her passionate fans. She makes sure to emphasize that rather than being Meltlilith she is the Mysterious Alter Ego Λ.

Normally in front of her sisters, she doesn't show off her charismatic side(really?). As one that refers to themselves as the personification of Lambda, the feeling of being a "Pro" is strong within this Spirit Origin.

Due to being influenced by Leviathan she is deeply envious. However, from the beginning she has been obsessed with the idea "the only thing I love". This obsession is so immense that it nears what could be considered to be a black hole therefore the aspect of deeply ingrained envy was there from the beginning, in reality.

Bond 4 スワンレイク:A




Swan Lake: A

As a result of holding back her sadism [Crime Ballet] under went a transformation. From the weakened attack power and evasion, she has become a dancer that is able to captivate the audience's hearts for a longer time and with even more beauty than what was possible before the transformation.

Perfect Fluid: B

With the authority granted by Leviathan, she is able to become completely liquid and transform the world around her into salt water. The only way to defeat the Melt who has undergone this transformation is through the use of an attack that pierces invincibility.

Melt Envy: EX

Corruption resulting from one of the seven deadly sins, envy. A transformed version of Meltlilith as a result of Leviathans influence. Weakening the other servants of her party's magical power, she is able to amplify her Noble Phantasm. At a glance it is a powerful skill, but at critical moments it is a devilish skill that undermines her other party members.

[The Glass-like Summer Dew]

Classification: Anti Unit
Range: 10~50
Maximum targets: 1
Blue Summer Palladion
According to Leviathan "Summer dew is read as 'summer', glass is read as 'the stars'."

Binding her target in a sphere of water. She dives into the megatsunami called forth by her and with the leviathan as her escort they speed through the waters at high velocity and then launching themselves out of the water with the bodies as a missile piercing through the target bound by the water sphere.

The surfaced Lambda looks like an elegant flying fish and while at the same time she also appears as legendary lance with the ability to destroy cities.

[The Elegy of the Seventh Deadly Sin’s Tsunami]
Rank: EX
Classification: Anti Barrier
Range: 50~500
Maximum Targets: 500

Leviathan, Melt Purge.

According to Leviathan, “Read ‘The Elegy of the Seventh Deadly Sin’ as ‘Envy's Summer Elegy’.” This must be speaking of a sin committed during the summer..?

Everything that is swept away by the tsunami is gathered in one place, locked within a sphere of water and annihilated by a Melt that has transformed into the form of a graceful water dragon, resting at the bottom of the ocean.

Extra リヴァイアサンは旧約聖書・ヨブ記に記された海に棲む巨大な魔獣のこと。






As recorded in the Old Testament and the Book of Job, Leviathan is a massive monster that resides in the ocean.

After the Last Judgement, God created massive beasts as a source of food for humanity. They were Behemoth who resided on the land and Leviathan (Livyatan) who made its home in the ocean. The two together were one. However, where Behemoth was a gentle natured herbivore, Leviathan was a non-peaceful beast. All leviathans are recorded as being female, and later on they were depicted as enormous snakes.

For humans, the ocean was an existence alongside death up until the middle ages. From this Leviathan became to be thought of as a devil like monster, and all of a sudden Leviathan came to be the symbol for the Seventh Deadly Sin, Envy.

In satanism, Leviathan is subordinate to Beelzebub and holds power and authority in Hell. Along with this Levithan is also Grand Admiral of the navies of Hell. On the other hand, in the Book of Job, Leviathan is just a large creature that swims around in the ocean making whirlpools and bringing forth waves.

"As long as we're a deity and a girl, we're a goddess right??? ☆"  BB-chan's simple interpretation explodes forth.
