Biography

Unlock	Description	Translation🛈🛈|nbx= for north american localization release and |bx = for fan english translation
Default	ケルト、アルスター伝説における無双の大英雄。 太陽神ルーの血を受けた『光の御子』であり、 異名はクランの猟犬。同じ真名で召喚される ランサーとは同一人物のようではあるが―― 肉体も精神も、若干「あちら」よりも年若い。	NA TL In Celtic mythology and the Ulster Cycle, there is a great hero who stands above all. A "Child of Light" born of the blood of the Sun God, Lugh. Also known as the Guard-Dog, he seems to be the same individual as the Lancer that is summoned with the same True Name. However, his body and mental age seem to be a bit younger than "the other one." A peerless great hero from the Celtic, Ulster mythology. The "Child of Light" that received the blood of the sun god Lugh, his alias is hound of Culann. He is sort of the same person as the Lancer that is summoned with identical True Name, but -- In both mind and body - he is somewhat more youthful than "that one".
Bond 1	身長／体重：184cm・71kg 出典：ケルト神話 地域：欧州 属性：秩序・中庸　　副属性：天　　性別：男性 ルーン魔術も「あちら」同様使いこなす。	NA TL Height/Weight: 184cm, 71kg Origin: Celtic Mythology Region: Europe Alignment: Lawful-Balanced Gender: Male Can use Rune spells just like "the other one." Height/Weight: 184cm ・ 71kg Source: Celtic mythology Region: Europe Alignment: Lawful ・ Balanced Attribute: Sky Gender: Male Has mastered Rune magecraft in the same way as "that one".
Bond 2	荒っぽいが気持ちのいい男。正義も悪党も 「どちらが上か」などと口にしないが、 根は正義寄り。世の理不尽、善悪の等価値さ などを飲み込めるほど、大人ではない。 動物使いでもある。特に犬とは相性抜群。	NA TL He's a wild but cool kind of guy. Even though he won't judge between justice or evil and decide which one is better, he cares deeply about being just in the world. But he isn't mature enough to accept the many unfairnesses that occur in the world. He's a creature tamer, and has a great affinity for dogs. A rough-looking pleasant man. Does not speak about "which is better" between justice and villainy, but his nature has a tendency towards justice. Not enough of an adult to understand things such the world's unreasonableness, the equal value of good and evil. He is also a beast-master. In particular, compatibility with dogs is excellent.
Bond 3	同じ真名で召喚されるランサーに比べて 重装な鎧を装備。それでも敏捷パラメーターは 「あちら」を上回るＡ＋。体の性能差ではなく、 年若いが故の前のめりな精神性が幾らかの差を 導くものとも考えられる。	NA TL Compared to the Lancer summoned with the same True Name, he wears heavy armor. Despite this, his dexterity parameter is A+, surpassing "the other one." It's not that he's more capable, but that he's younger, and overenthusiastic which causes several differences between them. Compared with the Lancer that is summoned with the same True Name, he is equipped with a heavy armor. And yet, the AGI parameter is A+, which exceeds "that one". One might think that this is not a difference in the performance of the body, but that the youthful mentality of pitching forward has lead to some sort of difference.
Bond 4	『穿ちの朱槍』 ランク：Ｂ／Ｂ＋　種別：対人／対軍宝具 ゲイ・ボルク。因果逆転の槍。 師スカサハより授かった朱色の槍、および槍術。 対人刺突、対軍投擲、の二種の攻撃法を持つ。	NA TL 『Gáe Bolg』 Rank: B/B+ NP Type: Anti-Personnel/Army The Spear which Reverses Causality. The scarlet spear and related arts which he received from his mentor, Scáthach. Capable of Anti-Personnel Thrusts and Anti-Army Throws. Piercing Crimson Lance Rank: B/B+ Type: Anti-Unit/Anti-Army Gáe Bolg. A spear of reversal of causality. A scarlet spear - and spearmanship - received from his mentor Scáthach. It has two kind of attack methods; the anti-unit thrusting and the anti-army throwing.
Bond 5	師スカサハに対する感情、想いについては、 「あちら」のランサーよりも心の内を幾分か 大きく占めている。若さ故か、時期故かは不明。 まさしく世の理不尽、善悪の等価値さを 認めることが出来ずにいるのか――	NA TL Compared to the other Lancer, he has a bit more affection for his teacher, Scáthach. It's unknown whether this is due to his age or how much time has passed. It's true he cannot accept the unfairness of the world, and the fact that it's all shades of gray, but... His feelings, thoughts towards his mentor Scáthach somewhat comprise a greater part of his heart than "that one". It is unknown if this is due to youth, or due to season. Evidently, he is still unable to accept the world's unreasonableness, the equal value of good and evil--
Clear Interlude 1
Extra	人類史の修復に挑むマスターの存在を、 彼は好ましく思うだろうし、力を貸すのにも やぶさかではないだろう。 ただし、注意すること。同一の真名を有する 「あちら」のランサーも同じ反応とは限らない！	NA TL He probably thinks it's commendable that his Master is attempting to correct human history, and most likely wouldn't mind lending a hand. However, you must be careful, as he may not respond the same as the Lancer with the same True Name. He will probably think favorably of the Master who is facing the challenge of restoring human history, and should have no reservations about lending his strength. But one must be careful. He is not bound to have the same reactions as "that" Lancer with the same True Name.
April Fool	ケルトサーヴァント クー・フーリンに進化する前の、若さにあふれたクー・フーリン。若いぶん血気さかん。イヌが友達。	Celtic-Type Servant Young Cú Chulainn prior to his evolution into blue bodysuited Cú Chulainn. Full of youthful energy. Very fond of dogs.
