Ruler (ルーラー, Rūrā?), Standard-Bearer who Correctly Guides the Holy Grail War and Heroic Spirit of the Arbitrator (裁定者の英霊, Saitei-sha no Eirei?), is a non-standard Servant Class brought forth for the purpose of presiding over Holy Grail Wars.
Quick Answers
How does the Fuyuki Grail utilize Ruler to protect the concept of the Holy Grail War?
What makes Ruler a non-standard Servant Class in FGO?
How does Ruler differ from other mediators in the Holy Grail Wars?
Qualifications
The criteria to be summoned for the Ruler Class is impartiality and possessing no desire for the Holy Grail. Those who qualify are most often Saints, and any Ruler summoned to preside over a Holy Grail will be a Saint under normal conditions.[1] Within other systems, like the FATE System, others who meet the criteria can be summoned.[2] One exception to the normal rule of impartiality is Amakusa Shirou Tokisada, an aberration who does not normally qualify, summoned by the Einzberns as the Heroic Spirit who was considered the closest to a ‘Saint’ that could possibly be found in the Far East.[3]
While Grand Classes do not exist for the Extra Classes, Galahad is considered the one who would be qualified to be in the position of a hypothetical Grand Ruler, as the "strongest judge in the Holy Grail War".[4] Qin Shi Huang of the Chinese Lostbelt, possessing a living body, appears with a Saint Graph that would be considered Grand in Proper Human History. Due to that, Sherlock Holmes wonders why Qin Shi Huang's Class is Ruler.[5]
Summoning
Under the Fuyuki Holy Grail War, the system installed within the Greater Holy Grail of Fuyuki allows for the summoning of a Ruler as an impartial authority to regulate the progress of a Holy Grail War[3] and protect the concept of the Holy Grail War itself.[6] The Greater Grail possesses its own logic as to when to summon a Ruler,[6] but the Einzberns, creators of the Greater Grail, are able to manipulate the system to call their own Ruler, though needing to compromise in summoning Amakusa due to it being an interference in the operation format of the war, in the World of Fate/Apocrypha.[3] The Ruler summoned gains two Command Spells for every Servant summoned in the Holy Grail War.[3]
Skills and characteristics
A Ruler is also summoned to preserve the laws of Heroic Spirits to ensure they won't be violated, such as the law of "the dead not leading the living", touted as the greatest law of Heroic Spirits,[7][8][9] and to maintain human history by preserving the illusion behind the Age of Gods so that people do not know about the truth behind it. The role of a Ruler is to arbitrate the truth and adjudicate all things in order to maintain human history.[2]
Known Rulers
- Servants marked with ‡ are also able to be summoned by Ritsuka Fujimaru in the Grand Orders.
- Servants marked with ⁜ are those who change class mid-story but do not display characteristics substantially different from the original class.
Rulers with modified Saint Graphs
Servants possessing the Class of Ruler through the modification of their Saint Graph rather than a standard summoning.
Non-Servants
Non-Servant beings with the Saint Graph Designation of Ruler.
Other qualifying heroes
| True Name | Current Class | Notes |
|---|---|---|
| BB | MoonCancer | She originally intended to be summoned in this Class but ultimately decided against it to avoid being bound by the rules.[12] |
| Galahad | Shielder | "Grand Ruler" doesn't exist. But if it did, it would be Galahad. |
| Lord Logres | Saber | She would have proper access to The Idle King Skill if summoned in this Class.[13] |
| Martha | Rider | |
| Mash Kyrielight | Shielder | She rejected the position because being a Ruler means being unbiased. |
| Qin Shi Huang | None | [14] |
| Richard I | Saber | Though he did not originally qualify, he attained the qualifications to become a Ruler after his death.[15] |
| Robert E. Lee | None | [16] |

Profile
A unique case that occurred in the Mooncell Automaton. Originally an advanced AI stationed for the sake of managing the health of the Masters, but it went wild due to a bug.
A cyber devil that ruled the far-side of the moon as a cancer that encroached the virtual world, obstructing the SE.RA.PH’s Holy Grail War.
A personification of illegal modifications, who forced the participants of the Holy Grail War to abide by the rules while she herself violated the rules all the time.
A kouhai-type devil heroine who puts all her efforts in manipulating the senpai (Master) as a cheerful, precocious kouhai - all while carrying out world destruction as if part of the breakfast.
“A well-behaved fight is boring, right?
I want to see everybody’s faces of suffering more!”
Just like this, one can tell in a glance that her behavioral and personality settings are twisted, but--- well, that is just your usual BB-chan.
Level 1 Bond
Height/Weight: 156cm・46kg
Source: Fate/EXTRA CCC
Region: SE.RA.PH
Alignment: Chaotic Good Gender: Female
“To tell the truth, a Ruler would have been preferable, but I called it off. A framework in which even the Game Master is bound by rules; that is just a machine.
For the sake of love, BB-chan will choke back her tears and torment all of humanity!”
Level 2 Bond
With a behavior that is wicked and excited, a headlong mastermind girl who plunges forwards even when her words and actions slip up.
The personification of a heart in love which, despite originally possessing an introverted character that could not step forward, earnestly becomes proactive for the sake of her beloved.
Despite enthusiastically playing the part of a villain, since she has no groundings in it, she just end up slipping up after all.
Her self-assured manner comes from latent sadistic preferences. The impish-type classification originate from this.
In addition, since she is the type that explodes after much enduring, she displays a tremendous, extreme sadism when the time comes.
“This is so fun!” - she gets high in such a manner while playing a villain, but hanging her head and getting depressed after retiring to the backstage and cooling off is also pretty much routine.
Although she created lesser AIs - the Alteregos - as familiars to help her with her job, she has a bad relationship with the Egos.
Even so that is only natural; for they are not “copies of BB’s personality” but AIs “built with her personality as a basis”, so each one have different opinions to that of their parent, BB.
This is why Meltlilith and Passionlip are designated Alteregos (different personality) and not avatars.
Level 3 Bond
"C.C.C."
Rank: A Type: Anti-Unit Range: 1~10
Maximum Targets: 1 person
Cursed Cupid Cleanser.
In the past, BB used a Noble Phantasm called Cursed Cutting Crater (Spiritual Particles Imaginary Pitfall), but now she brought out a new technique with a triumphant look while saying:
“I got tired of that after using it so many times. The theme this time is ‘cupid’ and ‘curelize’! Oh, but the cursed part does not disappear just because I become your ally. BB-chan’s curse is eternal!”
Drawing the Mooncell’s power, she changes into the shape of an invincible nurse. Immediately after, she draws malignant information from her territory - the imaginary space - and overwrites the surrounding channel (common awareness) into something chaotic.
Unfolding the Reality Marble, “BB Channel - Branch-off Edition”, and throwing the opponent into a melting pot of disorder... or so she says, but this is simply an syringe attack after BB has changed into nurse clothes.
Level 4 Bond
- Ten Crowns: D (EX)
An Authority-class transcedental skill.
It has been said that the ten crowns indicate the ten evil kings, and the seven hills indicate the abominable city of evil.
If you look at it in simple terms, this is a skill that turns all received injuries, occurred events, any and every result into “something nonexistent”.
As a matter of fact, BB is invincible so long she has this.
“Or so was in the past.
You see, an invincible cheat is disgraceful when you look up close, right?
So this is an unnecessary skill for the beautiful and cute BB-chan that we have now.☆ Oh, but it should be alright to use it just a little, right? Look, just like this!”
- Self-Modification: EX
A skill to remodel oneself.
The Mooncell’s AIs are endowed with an absolute order to “never improve one’s functions”.
However, having escaped such restrain thanks to a breakdown, BB began to expand her own functions. In order to raise her calculation abilities, she decomposes・preys upon NPCs, AIs and even Servants with a black noise and employs them as her own memory.
A retrofit-annex that disregards the danger of self-collapse, but BB became a super AI possessing a vast capacity as a result. Such state is like a city on reclaimed land that continues to build new structures even while sinking; or maybe something more like the monster of Frankenstein.
Level 5 Bond
The out-of-control AI that once caused the Case: CCC.
She was a management AI for the school infirmary, but a bug caused her self-preservation command structure go wild. Reaching the conclusion of “must preserve myself at all costs” for a certain reason, she ended up capturing NPCs, Servants and Masters and turning into a monster that continues to grow.
While declaring to “hate humans”, she brought in a certain Master to the far side of the moon and tormented him. Despite believing herself to be sane, from an objective point of view, she is clearly mad.
One can occasionally feel the inconsistency of excessive affection・disordered love and hate hanging on her behavior, but you should refer to the original CCC in regards to the causes behind this.
Also, her LCK parameter was of the lowest rank (E-), but it became EX thanks to BB’s world-distorting efforts (and devotion).
In other words, she once accomplished a “miracle” that was impossible to be achieved without the assumption of “EX Rank LCK”.
Interlude
Due the Kiara of the FGO world becoming one with the Kiara of the CCC world, as a countermeasure, the Mooncell temporarily turned BB into a Servant and dispatched her to the FGO world.
(that is because an user of imaginary(1) space such as BB is qualified to restrain Kiara).
Thus, despite being “a reproduction of the bug named BB”, she became able to intervene on the Seraphix as an independent virtual life-form.
The BB that appeared in the FGO world behaves in a impish manner just like during the “CCC Incident”, but for her that incident feels like something from tens of thousands years in the past.
In addition, she can only remain as a Servant like this in the FGO world and is also aware that she does not exist in the original “CCC world”. BB understand that she is a one-night-only dream.
BB places herself not as “a tool to save humanity”, but as “a devil that at times misleads, at times helps humanity”.
“So, it is futile to grow fond of me, you see? For even if you become madly in love with BB-chan, you’ll never be able to catch me (heart)”, or so she says with a triumphant look.ＢＢ - ムーンキャンサー

キャラクター詳細
かつてムーンセル・オートマトンに発生した特殊事例。
元々はマスターの健康を管理するために配置された上級AIだったが、バグによって暴走。
電脳世界を侵すキャンサー(癌)として月の裏側を支配し、SE.RA.PHの聖杯戦争を妨害した電脳魔。
聖杯戦争の参加者たちにルールを守らせながら、本人はルールを破りまくる違法改造の化身。
朝食感覚で世界を滅ぼす一方、明るくおしゃまな後輩としてセンパイ(マスター)を振り回すコトに全力を尽くす後輩系デビルヒロイン。
「お行儀の良い戦いなんてつまらないでしょう？
もっと皆さんの苦しむ顔が見たいのです！」
このようにパッと見は行動設定も性格設定も歪んでいるように見えるが───ま、いつも通りのＢＢちゃんである。
アンロック条件：絆レベルを１にすると開放
身長/体重：１５６ｃｍ・４６ｋｇ
出典：『Fate/EXTRA CCC』
地域：SE.RA.PH
属性：混沌・善 性別：女性
「ホントはルーラーが良かったんですけど取りやめました。ゲームマスターまでルールに縛られる構造なんて、それはもうただの機械ですから。
BBちゃんは愛のために、涙を呑んで人類の皆さんを苦しめるのです！」
アンロック条件：絆レベルを２にすると開放
言動は邪悪でイケイケ、台詞や言動が滑ってもそのまま突き進む猪突猛進な黒幕ガール。
本来は引っ込み思案で前に出られない性格だが、愛する者の為ならひたすらアクティブになる恋心の化身。
本人はノリノリで悪役を演じているのだが、素養がないのでどうしても滑ってしまう。
強気なのは潜在的に加虐嗜好があるため。小悪魔系なのはここに端を発する。
くわえて、耐えに耐えた後に爆発するタイプなため、発揮する時は凄まじいドＳっぷりを発揮する。
悪役を演じている最中は「さいっこうに楽しい！」とハイになっているが、舞台裏に引っ込んで冷静になる頭を抱えて落ち込むのまでがワンセット。
自分の仕事を手伝う使い魔として下位のAI、アルターエゴを作成したものの、エゴたちとの仲は悪い。
それもその筈、彼女たちは『BBの人格のコピー』ではなく『人格を元にして作られた』AIなので、親元であるBBとは意見がそれぞれ違っている。
メルトリリスやパッションリップがアバターではなくアルターエゴ（別人格）と呼称されたのはそのため。
アンロック条件：絆レベルを３にすると開放
『C.C.C.』
ランク：Ａ 種別：対人宝具 レンジ：１～１０
最大補足：１
カースド・キューピッド・クレンザー。
かつては霊子虚構陥穽（カースド・カッティング・クレーター）という宝具を扱ったBBだが、
「あれ、もうさんざん使ったので飽きました。今回のテーマはキュート＆キュアライズ！ あ、でも皆さんの味方になったからってカースドな部分は消えませんから。BBちゃんの呪いは永遠なのです！」
と、ドヤ顔で新技を持ち出してきた。
ムーンセルの力を引き出し、無敵のナース姿にチェンジ。そのまま、自分の領域である虚数空間から悪性情報を引き出し、周囲のチャンネル（共通認識覚）をカオスなものに上書き。
固有結界『BBチャンネル出張版』を展開し、相手を混乱のるつぼに叩き込む。……と色々言っているが、要はナースBBに着替えてからの注射器アタック。
アンロック条件：絆レベルを４にすると開放
○十の王冠：ＥＸ→Ｄ
権能クラスの超抜スキル。
十の王冠とは悪しき十人の王を指し、
七つの丘は忌まわしき悪の都を指しているという。
単純に見るのなら、受けた傷や起きた出来事、あらゆる結果を“無かったことに”するスキル。
事実上、これがある限りBBは無敵である。
なーんて、というのもかつてのお話。
ほら、無敵チートとか端から見るとみっともないし？
今回のキレイで可愛いBBちゃんには必要のないスキルなのでした☆ あ、でも少しぐらいなら使ってもOKですよ？ ほーらこんな風に！
○自己改造：ＥＸ
自身を改造するスキル。
ムーンセルのAIには“自己の機能を向上させてはならない”という絶対命令が備わっている。
しかし、故障からそのくびきから逃れたBBは自己機能の拡張を始めてしまった。計算能力を高めるためにNPC、AI、はてはサーヴァントまで黒いノイズで捕食・分解し、自らのメモリとして使用。
自己崩壊をいとわない後付け増築だが、結果、BBは膨大な容量を持つ超級AIと化した。その有様は沈水しながらも建築を続ける埋め立て地の都市か、フランケンシュタインの怪物のようでもある。
アンロック条件：絆レベルを５にすると開放
かつてケース・CCCを起こした暴走AI。
保健室の管理AIだったが、バグにより自己保存の命令系統が暴走。ある理由から『何を犠牲にしても自己保存を続ける』結論に至り、NPCたちやサーヴァント、マスターたちを取り込み、成長し続ける怪物になってしまった。
「人間は嫌い」と公言し、あるマスターを月の裏側に引き込んで苦しめた。本人は正常なつもりでいるが、客観的に見ると明らかに狂っている。
言動のはしばしから愛情過多・愛憎混濁とした矛盾性を漂わせるが、それが何に起因したものかはCCC本編を参照の事。
また、パラメーターの幸運値は最低ランクのE-だったが、BB本人の世界をねじ曲げるほどの努力（と献身）によって、幸運EXとなった。
つまり。『幸運EX』と仮定しない限り達成不可能な“奇蹟”を、かつて彼女は成し得たのである。
アンロック条件：「終幕 刻を裂くパラディオン(２／２) 」をクリアすると開放
FGO世界のキアラがCCC世界のキアラと同一化した事で、ムーンセルはその対抗策としてBBを一時的にサーヴァント化し、FGO世界に派遣した。
（キアラを御し得るのは虚数空間の使い手であるBBが適任だからである）
かくして、『BBというバグの再現』ではあるものの、BBは独立した電脳生命としてセラフィックスに介入できるようになった。
FGO世界に現れたBBは『CCC事件』の時のように小悪魔として振る舞うが、彼女にとって『CCC事件』は体感的な数万年前も前の事になっている。
くわえて、こうしてサーヴァント化できるのはFGO世界だけであり、元の『CCC世界』ではBBなど存在しない、という事も把握している。自分が一夜だけの幻である事をBBは理解しているのだ。
BBは自分を『人類を救う道具』ではなく
『人類を惑わしたり、時に助けたりする悪魔』と
位置づけている。
「だから、わたしを好きになっても無駄ですよ？ どんなにアナタがBBちゃんにメロメロになっても、わたしは決して捕まりませんから（ハート）」
と本人はドヤ顔で語っている。 - Ten Crowns: D (EX)
