Unlock Description Translation🛈
Default 二本の魔槍、二振りの魔剣を駆使する屈強の騎士。



NA Localization: A powerful knight and man of unparalleled beauty who wields two demonic swords and demonic spears. He was raised by Aengus, the fairy king and god of love, and Manannán, the god of the sea. Diarmuid was a member of Fionn mac Cumhaill's Knights of Fianna, and is said to have performed great feats when the knightly order fought alongside the fairy king Abarthach.

As he was a master of the sword as well as the spear, he was able to manifest here as a Saber. His Saber Spirit Origin emphasizes his aspect as a hero of myth and legend. It is much more costly and difficult to summon him as a Saber than as a Lancer, presumably because he possesses multiple Noble Phantasms of almost godly power.

Fan Translation: A sturdy knight who freely uses two magic spears and two magic swords.
A peerless handsome man raised by the God of Sea Manannan and Oengus, the God of Love who was also a king of fairies.
The best among the Knights of Fianna lead by Fionn mac Cumhaill, he supposedly played a great role during the Knights' united front with the Fairy King Abarta.

At this occasion, he has manifested with the Saint Graph of a Saber.
This is because he is proficient in not only the use of spears, but also swords―――
Still, in this Saint Graph, his aspect as a "hero of legends・mythology" is emphasized and - maybe due possessing multiple Noble Phantasm related to the gods - the cost・degree of difficulty regarding his summoning is greater than when he is a Lancer.

Bond 1 身長/体重:184cm・85kg

属性:秩序・中庸   性別:男性

NA Localization: Height/Weight: 184cm, 85kg
Origin: Celtic Mythology, Knights of Fianna
Region: Ireland
Alignment: Lawful-Balanced
Gender: Male
The skill "Love Spot" is typically not used by this Spirit Origin, and is instead sealed.

Fan Translation: Height/Weight: 184 cm・85 kg
Source: Celtic Mythology, Knights of Fianna
Region: Ireland
Alignment: Lawful・Neutral
Gender: Male
The skill "Love Spot" is fundamentally not employed in this Saint Graph. It was put under control.

Bond 2 忠義に篤く、誠実さを有する高潔な英霊。



NA Localization: A virtuous Heroic Spirit who is both loyal and cordial. More or less the same person as his Lancer self, his Saber self nonetheless more knightly. Whether consciously or not, he also tends more toward self-affirmations.

His Spirit Origin and performance have both improved over his Lancer iteration, but this has also made him more difficult to summon. This Spirit Origin cannot manifest until certain conditions are met, regardless of how skilled the summoner may be, and the opportunity to do so may fade away like so much mist.

Fan Translation: A virtuous Heroic Spirit who is loyal and sincere.
Fundamentally the same individual than when he is a Lancer, but his self-awareness as a "knight" was strengthened by being summoned as a Saber.
Enjoys fighting against strong opponents and shows no scruples in pursuing that. Also, he may be aware of this or not, but his self-esteem is somewhat stronger than when he is a Lancer.

The performance of his Saint Graph has increased when compared to his time as a Lancer but, on the other hand, the degree of difficulty of his summoning also went up.
No matter how excellent is the competency of the summoner, this Saint Graph will not be established unless specific conditions are met and it may even vanish like mist.

Bond 3 魔力放出(跳躍):A



NA Localization: Mana Burst (Jump): A
As Diarmuid was raised by the gods, he gained a superhuman ability to leap great heights and distances. In consequence of this, his agility is lower than when he is summoned as a Lancer. This Mana Burst allows him to increase his mobility in short, explosive bursts while also increasing his overall offensive ability.

The Knights of Fianna's Honor: B
Diarmuid's extraordinary resolve. His knightly gallantry made manifest.

Fan Translation:Mana Burst (Leap): A
Having been raised by the gods, Diarmuid acquired superhuman jumping power.
Upon manifesting as a Saber, he is endowed with this skill in exchange for his AGI parameter declining when compared to his time as a Lancer.
By emitting magical power, he improves his mobility and raises overall attack power.

Honor of the Knights of Fianna: B
Diarmuid's exceptional resolve.
The mentality of a chief-knight given shape.

Bond 4 『憤怒の波濤』

NA Localization: 『Móralltach』
Rank: B

Waves of Fury.
Of all the powerful armaments in Diarmuid Ua Duibhne's possession, none can match this fearsome demonic sword.

The Single Stroke Lethal Blow:
The First Strike Sure Victory.

The unleashed demonic blade ensures a definitive victory for Diarmuid and casts his enemies down in death and defeat.

Fan Translation: Surge of Fury
Type: Anti-Unit Noble Phantasm
Range: 1 ~ 20
Maximum Target: 1 person

If one were to point out the most powerful among the many armaments that Diarmuid Ua Duibhne employs, it could be no other than this fearsome magic sword.
One-hit kill; securing victory on the first strike.
The unsheathed magic sword bestows Diarmuid with certain victory and brings about defeat and death to his opponent.

Bond 5 運命をも操るが如き魔剣モラ・ルタは、



NA Localization: The demonic blade Móralltach, so powerful that it seemingly commands even fate, was given to Diarmuid by Manannán, the Celtic god of the sea and the otherworld. Manannán also bestowed the Noble Phantasm Fragarach to the sun deity Lugh, and was known to possess and give away many other Noble Phantasms.

Once its True Name is revealed, Diarmuid executes a superhuman leap at his enemy. At that moment, Móralltach takes a guise similar to that in the legend of "Manannán's Legs," becoming a triple blade to dispatch Diarmuid's enemies.

Fan Translation: The magic sword Moralltach, which appears to manipulate even fate, was bestowed by the Celtic god of seas and the otherworld, Manannan.
This Manannan was the divinity that bestowed the Noble Phantasm Fragarach (and others) to the Sun God Lugh, and was an existence that possessed, donated many Noble Phantasm.

Once the True Name is released, a diving attack that capitalizes on a super-jump that surpasses human intellect (which became apparent by manifesting in the Saber Class) is executed. At this time, Moralltach turn into three blades - in a likeness to the "feet of the god Manannan" spoken in legends - and cut the enemy to pieces.

Requires Bond Level 5 and Clear Interlude 1
Extra 逸話によれば、真に生死を懸けた冒険へと赴くディルムッドは魔剣モラ・ルタと魔槍ゲイ・ジャルグを持ち歩き、危険は少ないと判断した際には魔剣ベガ・ルタと魔槍ゲイ・ボウを持ったという。



NA Localization: According to legend, whenever Diarmuid went on a life-or-death adventure, he took the demonic blade Móralltach and demonic spear Gáe Dearg. For any less dangerous expeditions, he instead brought the demonic blade Beagalltach and demonic spear Gáe Buidhe.

When Diarmuid died, he was wielding the latter set of weapons.

Had he ventured into the mountains with his more powerful weapons, the demon boar would have been defeated, and the strongest of the Knights of Fianna may have lived a longer life.

Fan Translation: According to anecdotes, Diarmuid would supposedly carry the magic sword Moralltach and the magic spear Gae Dearg when heading out to adventures that he truly had to bet his life on, and would bear the magic sword Beagalltach and the magic spear Gae Buidhe whenever he judged there would be little danger.

―――at the moment of his death, Diarmuid was carrying the latter set of equipments.

If he were to be carrying the former set when entering that mountain, maybe the magic boar would have been defeated and the strongest knight of the Knights of Fianna would have lived a long life.

April Fool びだんしサーヴァント


Handsome-Type Servant

Diarmuid gained sword powers and now he's even more handsome. He no longer unconsciously attracts women. Really, really, really wants to fight the King of Knights.


  • He shares the exact same ATK values at minimum with Bradamante.
  • He shares the exact HP values at both minimum and maximum with Lakshmibai.
