Stories
7Character details
Descendant of the Celtic God of War, Nuadha. Leader of the Knights of Fianna.
A great hero who protected the land of Erin (Ireland) by defeating an evil Divine Spirit that manipulated flames and sleep, and repelled invaders and demonic creatures using his wits and might.
Knowledgeable and trained in magecraft, he would normally possess many abilities and Noble Phantasms.
Profile 1
Height/Weight: 181cm, 63kg
Origin: Celtic Mythology
Region: Europe
Alignment: Neutral-Balanced
Sub-Attribute: Heaven
Gender: Male
As a Lancer, his Noble Phantasms are his spear and healing power.
Profile 2
Serving the High King of Erin, he was a man who attained appropriate achievements to be admired as both the leader and the greatest knight of the glorious Knights of Fianna.
He defeated the fallen Divine Spirit Aillen, a demonic boar, a horse from the underworld and finally Nuadha, the God of War himself.
It has been said that he was a great man who in times of peace would go on hunting trips with his subordinates in the knight order.
Profile 3
Though the path he'd taken as a great hero was beyond reproach, he was destined to have woman troubles.
His misfortunes started when he was charmed by a pair of beautiful sisters and received a curse from them.
Disaster ensued after that, he lost 7 years of his life fighting a fairy over his first wife, then the quarrel with his third wife, Grainne, ultimately led to the end of his order of knights.
Profile 4
The problem was not with the women, the problem was with himself, but Fionn mac Cumhaill never thought of it that way.
Exactly what went wrong? Even after he manifested as a Servant, he still couldn't understand.
Profile 5
『Mac an Luin』
Rank: A
NP Type: Anti-Army
The Undefeated Violet Healing Flower.
Has auto-attack functionality, and is able to nullify any mental interference.
By releasing its True Name, it can control water from the God of War, Nuadha, and concentrate the stream into a single powerful blast.
The True Name of this Noble Phantasm is the same as his sword which is often seen as the same lance that slew the being Aillen.
Additional profile
Having served the king of Ireland during his former life, he has no reservations about working under someone as a Servant. He desires to be a hero that serves the people.
Also, perhaps because he materializes with a youthful appearance, his mental age is also younger than his older days. (He has retained all his memories until his later years).

- Bond Level 1
- The Knights of Fianna. You must know that name as well. It's the name of the order of knights who protected Erin, or as you know it now, Ireland.
- Bond Level 2
- The Knights of Fianna were just and noble. I was proud of each and every one of those warriors. Even now, I can still remember their faces when I close my eyes...
- Bond Level 3
- I was called a hero, and while it's true that I defeated many an evil monster, I couldn't have kept Erin safe on my own. I was only able to do that thanks to my knights.
- Bond Level 4
- It's nothing to be proud of, but… I seem to be destined to have more than my fair share of woman troubles. I've made a lot of women cry… No, I swear I would never make you cry, Master.
- Bond Level 5
- ...I've made a lot of mistakes. My good looks enticed a pair of beautiful sisters. I even ended up fighting a fairy over my first wife. Then with my third wife, Gráinne… Never mind, let's stop talking about this.
- Conversation 1
- If you wish to fight, I, protector of Erin, will lend you my strength. Master, your goal is ripe with the nobility I so love.
- Conversation 2
- I am a knight. I once served the High King of Erin and was ordered to protect the land and the people. I wonder, will you be using me as that High King did?
- Conversation 3
- I am the hero of Erin, but I am also a knight. I will not hesitate to serve someone, and if I can work for the good of the innocent, then I have no complaints.
- Likes
- I like justice, righteousness, nobility, and...grace, I suppose.
- Dislikes
- What do I hate? Hmmm, I don't really hate anything... Oh, but betrayal is never good. A person must not betray the trust of another.
- About the Holy Grail
- If an omnipotent wish granting machine does exist, I would wish for... Ah yes… I would wish for my destiny of woman troubles to be changed. As you can see, I'm beautiful. That's caused more than a few disasters.
- Conversation 4
- Diarmuid Ua Duibhne, the best of my Knights of Fianna! I never thought the day would come that I would fight alongside him again…
- Conversation 5
- You have so many beautiful Servants... But I mustn't. My beauty coupled together with theirs would only invite a tragic fate to befall us...
- Conversation 6
- How beautiful... What a lovely maiden. I can see why she left a mark on history. Oh no, no, no. This is no good. A damsel mustn't be left out on her own in danger, and any knight who permitted this to happen would surely have his reputation tarnished. And so, Master... I shall go fulfill my knightly duties... Understood?
- Conversation 7

Understood?
- Conversation 8
- It's been a while since I've seen that sword...Diarmuid the knight.
- Conversation 9
- So you are the rumored King Fergus...or rather, Sir Fergus. It seems we never run out of things to talk about! Now come, hand me your goblet!
- Conversation 10
- Ah...what a lovely maiden... Oh...I beg your pardon. It's nothing, my lady. I hope you have a wonderful day.
- Conversation 11
- I sense some faeries. They are both nostalgic and terrifying at the same time... But if they have manifested here in Chaldea, there shouldn't be any issue. Either way...Master, would you be kind enough to introduce them to me? Hahaha. Just as fellow knights, I promise you.
- Conversation 12
- I see, a sort of fairy from another land... She is so lovely. By the way, why do you keep following behind me?
- During an Event
- I feel something... Is this the presence of a beautiful woman?
- Birthday
- So this is the day you celebrate your birth? The custom of celebrating births is a magnificent thing. Allow me to offer you a blessing as well. Yes, from this day forward, you are a member of the glorious Knights of Fianna.
