Bond 2 英霊アルトリア・ペンドラゴンと同一の過去と伝説を有する完全な同一人物にして、別人。


A completely identical, and yet different person than Heroic Spirit Artoria Pendragon - possessing the same past and legend as her.

He has manifested in this world while taking an integrous form that can be described as an "ideal prince" or a "knight of silverly blue".
A heroic spirit visiting from a different world, or so he says but---

Bond 3 ○カリスマ:B



Charisma : B

A natural talent to command an army corps.
At this occasion, Arthur has been specialized for battle against large animals.
Since the allies cannot keep up when fighting against large animals, and he ends up all alone, there is no place to display his Charisma.

Gigantic Beast Hunting: A
King Arthur fought against and managed to completely defeat all the magic beasts that attempted to trample down Britain.
A skill that denotes having abundant combat experience against giant enemy lifeforms.

Bond 4 『約束された勝利の剣』

ランク:EX 種別:???



Sword of Promised Victory

Rank: EX
Type: ???
The shining holy sword that saves the planet.
A golden blade that repels pretty much any evil, built to defeat an outside enemy that destroys the planet.

The shape taken when six of the holy sword’s "Thirteen Seals" are released.
Although it still cannot display its true power, since over half of its seals (in other words, seven or more) have not been released───
Even so, this is unmistakably an intense light that defeats a great evil.

In this work, the release of the "Bedivere Seal" is being automatically acknowledged, making one consider the hypothesis of a decisive battle against a greater being.

Bond 5 自分は本来は別世界・異世界に属する英霊であり、とある強大な敵対者、悪相の兆しを追い求めてこの世界へと辿り着いたのだ―――と本人は告げる。



A heroic spirit belonging to a different world or parallel universe, who reached this world after chasing after a certain powerful antagonist, evil omen - so he tells.

Astonishing words whose veracity cannot be judged even with the help of Chaldea’s system but, at the very least, he won’t spew lies to his Master.

He places his wholehearted trust towards his Master.
Deception and betrayal are unthinkable.
