Bond 2 イアソンは父であるアイソンの異父兄弟ペリアスに、彼が簒奪した王位の返却を要求したが、条件として黄金の羊毛を求められた。


NA Localization: Jason demanded that Pelias, his father's half-brother, return the throne to him as the rightful heir. Pelias agreed if the Golden Fleece was brought to him.
And so, Jason built a ship and recruited adventurers throughout Greece. The ship was called the Argo, and the crew were called the Argonauts.

Fan Translation: Jason demanded the half-brother of his father Aeson, Pelias, to return the throne he had usurped, but as a condition he was asked for the Golden Fleece. Then he built a ship, and recruited adventurers from all over Greece.
The ship's name was Argo, and the crew was called the Argonauts.

Bond 3 ヘラクレス、カイニス、アタランテ、カストロ、ポルクス、オルフェウスなど、様々な英雄が集った船での大冒険の末に、イアソンは羊毛を奪取した。だが、その際にイアソンはメディアを籠絡し、妻とした。してしまった。

イアソンは地位も名誉も全て奪われ、アルゴー号の 船首で首を吊ろうとした瞬間、舳先に押し潰され 死に絶えたという。

NA Localization: Heracles, Caenis, Atalante, Castor, Pollux, Orpheus, and other heroes assembled on board this ship, and after a great adventure, Jason managed to return with the fleece. However, along the way, he had also made Medea his wife. What a careless choice...

...The details of what happened will not be stated here. Jealousy brought forth hatred, and hatred summoned revenge.
Jason lost his position and fame, and as he tried to hang himself off the Argo, its bow fell and crushed him instead.

Fan Translation: At the end of a great adventurer in the boat in which several heroes like Heracles, Caenis, Atalante, Castor, Pollux, or Orpheus, Jason seized the fleece. But at that moment Jason ended up ensnaring and marrying Medea. He did.

……It's not necessary to talk in detail.
Envy called hatred, and hatred summoned revenge.
Jason was deprived of all his status and honor, and in the instant he tried to hang himself from the Argo's bow, he died out crushed by the ship's prow.

Bond 4 求めし金羊の皮:なし

彼が冒険の末に手に入れた金色の毛をした 羊の皮。わりとふわふわしてて心地いい。

窮地に陥ったとき、自らの身を捨てるような 振る舞いで脱することができる。
火事場の閃きにおいては、他の追随を許さない。 ただし、イアソン本人はこの能力をひたすら 嫌がっている。何しろ、毎回死ぬような目に 遭わなければ閃きが届かないからだ。

かつてアルゴー号に乗った者を 勇気凜々にする。

NA Localization: The Desired Argon Coin: None
The golden sheep's fleece that Jason obtained from his adventure. It's fluffy and has a pleasant texture.

Inspiration at Death's Door: A
When caught in a dilemma, he can act as if he's throwing his life away in order to escape.
Nobody can beat him when it comes to being quick on his feet during a crisis. However, Jason really hates this ability, since the only time inspiration reaches him is when he's placed in a dire, deadly situation.

Conquering the Sea with Friends: B++
Fills those who've sailed aboard the Argo with courage.
Encourages those who've not sailed aboard the Argo...somehow.
Let's just call it a pseudo-Charisma ability that's super limited.

Fan Translation:The Requested Golden Fleece: None The fleece of golden fur he obtained at the end of his adventure. Quite fluffy and comfortable.

Insight at the Jaws of Death: A
When falling in a predicament, he can escape by acting as if he was throwing away his life.
In terms of insight in moments of crisis, no one can come up with him. However, Jason himself hates this skill with all his heart. After all, insight won't reach him if his life isn't threatened.

Conquering the Distant Sea Routes with Friends: B++
Fills those who once sailed on the Argo with courage.
Somehow gives the sensation of encouraging those who didn't sail.
Could be said to be a super-limited subspecies of the Charisma skill.

Bond 5 『天上引き裂きし煌々の船』

ランク:B++ 種別:対軍宝具
レンジ:1~10 最大捕捉:50人


逆に明らかに立ち位置が悪役だったりすると、 『びっくりするくらい、誰も乗ってきませんでした(サボタージュ)』となり、威力も著しく低下する。

NA Localization: 『Astrápste Argo』
Rank: B++
NP Type: Anti-Army
Range: 1 - 10
Maximum Targets: 50

The Radiant Ship that Tears the Heavens.
Aid received from the Argo, where the heroes aboard execute a coordinated attack.
The better standing Jason has, the greater both the crew's unity and the number of attacks made.
In contrast, if he is seen as a villain, the ship will suffer from the sabotage of being "surprisingly" empty, and the Noble Phantasm's strength will drastically decrease.

Fan Translation: 『Brilliant Ship that Tears the Heavens』
Rank: B++ Type: Anti-Army
Range: 1~10 Maximum number of targets: 50 people

Astrapste Argo.
Reinforcement from the Argo. The heroes that sailed on the ship begin a simultaneous attack.
The more righteous is Jason's position in battle, the larger the support from the crew becomes, and the frequency of the attacks will increase too.

On the contrary, if his position is clearly that of a villain,
it will turn into a situation of 『surprisingly, nobody sailed (sabotage)』, and its power will remarkably drop.

April Fool せんちょうサーヴァント


Captain Servant

The captain of the Argonauts everyone loves. He answered the long-awaited summoning as a Servant, but maybe as a punishment for his past actions he has completely become a gag character.


  • Jason was an Enemy only character in Okeanos. He did not engage in battle as a Servant, but rather as Demon God Forneus.
  • He is the only bronze and 1★ Saber.
  • Each of his Cards features a Argonaut-member Servant: Heracles in Buster, Atalanta in Quick and Medea (Lily) in Arts.
  • Medea (Lily) and Heracles are featured in his final ascension artwork.
  • Jason features a unique defeat animation. When he is defeated but doesn't fade away, instead of the normal backwards-leap animation he comically runs away.
