Default	ラスベガスに現れた謎のサーヴァント。 その正体はあまりにも不明だが、一流のバレエダンサーであり、芸術を司る女神であり、今回はさらにフィギュアスケーターとしての才能まであったコトを見せつける、水とペンギンのサーヴァント。 ベガスにある五大カジノの一つ『水天宮』のオーナー。 カジノはスロットがメインだが、とにかく風速が早い……回転が速いという噂。 一文無しになって路頭に迷ったお客様（サーヴァント）たちの行方は杳として知れず、おそらくラムダに囚われ経験値にされてしまったのでは、と噂されている。	NA TL NA Localization: A mysterious Servant who showed up in Las Vegas. No one really knows who she is, but she's gone out of her way to show off her skills as a first-class ballerina, a goddess of artistry, and even a gifted figure skater. On top of all this, she is also a Servant with the power to control both water and penguins. More significantly, she is also the owner of Suiten Palace, one of the five major casinos in Vegas. Suiten Palace is known for its incredible slot machines, though rumor has it that the slot machines spin so fast it's hard to tell what you might be stopping on! All the customers (Servants) who lose their fortunes in her casino wind up missing. Some say Lambda has captured them and turned them into EXP cards... Fan Translation: A mysterious Servant who appeared in Las Vegas. Her true identity is hidden, but it is known 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 as the main attraction. However, there's a rumor of gusts of wind blowing out of nowhere, spinning the slot machines at a wicked speed. The whereabouts of the Heavenly Water Palace's patrons (Servants) who had been left aside on the streets without a penny to their name are unknown to this day. Speculations predict that they were trapped by Lambda and turned into experience points...

Changing her primary essence from Sarasvati to Leviathan has lowered this skill's rank.

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。 好戦的で無慈悲。かつ加虐趣味を持つという女王属性。 構造的な美しさを好み、醜いものを許さない潔癖性。 自分が完璧な存在であり、自分だけですべてを成し得られると自負しているのでプライドが高い。 ……といういつもの彼女だが、今回はプロのフィギュアスケーターとして観客を沸かせる事を快楽としている為、加虐趣味は（やや）封印されている。 とはいえ、『自分基準で、自分の美しさを絶対としている』核の部分は変わらない。 他の水着剣豪たちがどれほど美しく人気があろうと、「ふうん、そうなの。でも、一番美しいのは私でしょう？」と優雅に微笑む。	NA TL NA Localization: A prima donna above the water, figure skating charismatically across the surface. She calls herself the queen of the sea and claims to unleash all manner of waves. She is both an aggressive and merciless queen, dominated almost entirely by her wickedly sadistic side. She prefers structural beauty, and she is very sensitive to things she finds ugly or otherwise aesthetically unpleasing. Believing herself to be capable of anything, Meltryllis prides herself in her absolute perfection...which really isn't anything new. But this professional figure skater persona of hers does love hyping an audience up, which...somewhat mitigates her sadistic tendencies. Her absolute belief in herself as the gold standard for beauty and perfection remains quite unchanged. No matter how beautiful and popular the other swimsuit Swordbeauties are, she will smile elegantly and say, "Is that so? But I'm still the most beautiful, right?" Fan Translation: An aquatic prima donna and a charismatic figure skater. Riding the ocean waves, she refers herself as the Queen of the Seas. Ready to fight at a moment's notice without mercy. A queen who enjoys tormenting others as a hobby. She loves the structural beauty of things, and will not permit anything ugly that opposes what she believes to be perfection. As she is a perfect existence, she is able to do anything by her power which she prides herself upon. She holds herself highly for this...... Well, that's her typical self. This time she appears as a professional figure skater who drives the audience and shows them a good time, so she's biting back on the bullying... mostly. With that being said, her personal motto of "I myself am the standard for beauty, and my beauty itself is absolute in this world" hasn't really changed. No matter how beautiful or popular the other Swimsuit Swordmasters are, gracefully she would brush them off. "Oh, is that so? But, I'm 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。 自分はメルトリリスではなく謎のアルターエゴである、と主張している。 普段であれば姉妹たちの手前、あまりカリスマぶる事はないのだが（そうかぁ？）、 表現者・ラムダを名乗っているこの霊基ではとにかくプロ意識が強い。 また、リヴァイアサンの影響で『嫉妬深く』なっている、という触れ込みだが、もともと彼女は『自分が愛するただひとつのもの』への執着・愛情がブラックホール級に重いので、嫉妬深いのは元からなのであった。	NA TL NA Localization: She hides her identity because she's a star. She conceals her private life out of consideration for her passionate fans, and as a sort of reward for them. This is why she is so adamant about claiming not to be Meltryllis, but rather the Mysterious Alter Ego. Normally she sees no point playing at being charismatic for her sisters (oh really?), but as this Spirit Origin takes the name of the expressionist Lambda, she is a professional through and through. Leviathan has also made her become envious...at least that's what's publicized. However her egotistical attachment and love were always quite...intense, like the pull of a black hole, while her jealous and envious nature has always been there. Fan Translation: A star doesn't reveal their true self. As for her private life, she would only divulge any detail for simply one reason: it's out of her own thoughtfulness as a reward for her passionate fans. She makes sure to emphasize that she is not Meltryllis but Mysterious Alter Ego Λ. Normally, in front of her sisters, she doesn't flaunt her charismatic side (Is that so?). As the personification of lambda, the feeling of being a pro is strong within this Spirit Origin. Due to Leviathan's influence, she is deeply envious. However, from the beginning she has always been obsessed with the idea of "the only thing I love". This obsession is so massive that it nears what could be considered as a black hole. In reality, the aspect of deeply-ingrained envy was present from the beginning.
Bond 4	○スワンレイク：Ａ スキル『加虐体質』を抑えた事により『クライム・バレエ』が変化したもの。 攻撃性・回避性を薄めたかわりに、より長く、美しく、観客を魅了する踊り子となった。 “最高のトリプルアクセル”チャンスが訪れる事も。 ○完全流体：Ｂ リヴァイアサンの権能。自身を流体に、世界を海水で満たす。これを使ったメルトを倒せるのは、無敵貫通による攻撃のみである。 ○メルトエンヴィー：ＥＸ 七つの大罪・嫉妬による汚染。 メルトウイルスがリヴァイアサンの影響で変化したもの。パーティのサーヴァントたちから魔力を奪い、宝具の威力を向上させる。 一見すると強力なスキルだが、ここぞという時でパーティの足並みを狂わす魔のスキル。	NA TL NA Localization: Swan Lake: A Crime Ballet has transformed due to her Sadistic Nature skill being suppressed. In exchange for her ATK and Evade weakening, she has turned into a dancer even more enthralling and more beautiful to her audience. There may be an opportunity for her to pull off the "ultimate triple axel" one day. Complete Fluidity: B An Authority of Leviathan. They will fill the world with sea water by turning themselves into a fluid being. The only thing that could defeat Melt in this form would be an Ignore Invincible attack. Melt Envy: EX Contamination due to Envy, one of the seven deadly sins. Leviathan caused her Melt Virus skill to change. This skill steals the magical energy from other party members to increase her own NP Strength. At first glance it may seem a powerful skill, but it's actually quite the evil tactic that tends to mess with a party's cohesion. Fan Translation: Swan Lake: A By holding back her sadism, Crime Ballet underwent a transformation. From weakened attack power and evasion, she has become a dancer who 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 turn into liquid and transform the world around her into seawater. 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 One of the seven deadly sins: Envy. A corrupted version of Melt Virus due to Leviathan's influence. By weakening other party Servants' mana, 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.
Bond 5	『その夏露は硝子のように』 ランク：Ｂ＋　種別：対人宝具 レンジ：１０～５０　最大捕捉：１人 ブルーサマー・パラディオン。 ラムダ曰く、『夏露はなつ、硝子はほしと読むのよ』とのこと。 対象を水球で囲み、拘束。自身は招き寄せた大津波にダイヴし、従者であるリヴァイアサンたちと共に海中を高速移動し、その加速を以て自身をミサイルのように撃ち出し、対象を水球ごと貫く。 地上に飛び出したラムダの姿は優雅な飛び魚のようにも、都市を滅ぼす神話の槍にも見えるという。 『大海嘯七罪悲歌』 ランク：ＥＸ　種別：対界宝具 レンジ：５０～５００　最大捕捉：５００人 リヴァイアサン・メルトパージ。 ラムダ曰く、『七罪悲歌は なつみひか と読みなさい』とのこと。夏の罪とかけているのだろうか……？ 天と地を海で満たし、大津波を引き起こす。 津波にのまれたものたちは渦巻きによって一カ所にまとめられ、水玉（牢）に閉じ込められた後、完全流体のまま竜を模したメルトリリスによってかみ砕かれ、海の藻屑と化す。ラスベガスを囲む海はこの宝具を常時展開したものである。	NA TL NA Localization: 『Blue Summer Palladion』 Rank: B+ NP Type: Anti-Personnel Range: 10 - 50 Maximum Target: 1 The Summer Mist is Like Glass. According to Lambda, one should read it more as "Summer Is Like a Star." The target is restrained inside a water sphere while she dives into the water and swims at high speed with numerous Leviathans, her attendants, by her side. After accelerating, she shoots herself out like a missile to pierce the target still trapped within the sphere. The Lambdas that jump out to the surface may look like graceful flying fish, or even a legendary spear that could destroy a city. 『Leviathan Melt Purge』 Rank: EX NP Type: Anti-World Range: 50 - 500 Maximum Target: 500 The Great Sea's Howl, The Seven Deadly Sins Elegy. According to Lambda, the "seven deadly sins" should be read as "seven summer sins." Apparently alliteration is key, and their rarity is high. Heaven and earth are filled with the sea to create a giant tsunami. Those engulfed by the tsunami are all collected in one place by a tornado. They are then trapped inside a spherical water prison, where Meltryllis, now in the form of a completely liquid dragon, bites the sphere, bringing the enemy to a watery grave. The sea that surrounds Las Vegas is made possible by constantly deploying this Noble Phantasm. Fan Translation: [The Glass-like Summer Dew] Rank:B+ Classification: Anti Unit Range: 10~50 Maximum targets: 1 Blue Summer Palladion According to Leviathan, "Summer Dew" is read as "Summer" and "Glass" is read as "Stars". Binding her targets in a sphere of water, Lambda dives into a megatsunami called forth by her. With Leviathan as her escort, they speed through the waters at a high velocity, launching themselves out of the water, their bodies piercing through the water-bound targets like missiles. Resurfacing, Lambda assumes the form of an elegant flying fish while also being a mythical lance with the ability to destroy cities. [Lament 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 "Lament of the Seventh Deadly Sin" as "Summer Sea Song". Is this the work of a summer sin...? Everything that is swept away by the tsunami is gathered in one place, locked within a sphere of water, and annihilated by the Meltryllis who has assumed 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。 神は最後の審判の後、 人類の糧となるべく巨大な魔獣を創造した。 それが陸に棲む魔獣ベヒモスと、 海に棲む魔獣リヴァイアサン（レビィアタン）である。 リヴァイアサンとベヒモスは番（つがい）であるとされ、ベヒモスは温厚な草食獣であったが、リヴァイアサンは凶暴な獣だという。 リヴァイアサンはすべて雌であるとされ、後に巨大な蛇のイメージで描かれることになる。 海が人々にとって死と隣り合わせだった中世以前、その凶暴性から悪魔とみなされるようになり、 ついには『七つの大罪』のうち『嫉妬』を象徴する大いなる悪魔として流布された。 リヴァイアサンは悪魔学においてサタン、ベルゼバブに次ぐ地位を持ち、さらに地獄の海軍大提督としての権限を持つ。ヨブ記では、あまりにも巨大であり、ただ泳ぐだけで海が渦を巻き、荒波が押し寄せるという。 「どんなに凶暴でも、 　神性があって女の子なら女神ですよね☆」 なんてＢＢちゃんの超解釈が炸裂している。	NA TL NA Localization: Leviathan is the Demonic Beast that lives in the sea, mentioned in the Book of Job in the Old Testament. After the Final Judgment, God created a giant Demonic Beast that would become food for humanity, which is how the Demonic Beasts Behemoth of the land and Leviathan (Livyatan) of the sea were created. Leviathan and Behemoth are said to be a pair, where Behemoth is the mild-mannered herbivore and Leviathan the violent carnivore. All Leviathans are said to be female, and they are usually depicted as giant serpents. During the Middle Ages, the sea was perceived as a place of death, and its violent nature soon led people to think of it as the devil, ultimately leading it to represent one of the seven deadly sins: envy. In demonology, Leviathan holds a position next to Satan and Beelzebub, as well as having Authority as a Great Admiral of hell's navy. In the Book of Job, it is said that its massive body would cause the sea to whirl and induce raging waves just by swimming. "No matter how violent they are, as long as they have Divinity, that'll make them goddesses if they're female☆" ...At least, that's BB's off-the-wall interpretation. Fan Translation: 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 the Behemoth who resided on the land and the Leviathan (Livyatan) who made its home in the ocean. Together, the two were one. However, while Behemoth was a gentle-natured herbivore, Leviathan was a vicious beast. All leviathans are recorded as being female, and later on, they are 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. Besides that, Leviathan is also the 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 have Divinity and we're girls, that makes us goddesses right??? ☆" BB-chan's simple interpretation explodes forth.
April Fool	プリマサーヴァント アイスショーで華麗なダンスを披露するフィギュアスケーター。セレブはどこにいってもサインをせがまれるので外出時にはサングラスが必須。	Prima Ballerina-Type Servant A beautiful figure skater who shows off her elegant dance on the ice. Celebrities always get pressed for autograph when they're outside, that's why she always wears a pair of sunglasses.
