One of the Knights of the Round Table from Arthurian legends.
His Class is Saber, but he is often summoned as an Archer due to his renown with a bow.
The tale of Tristan and Iseult, the woman he loved, is a legend boasting outstanding popularity in Europe.
Tristan is a child born from Rivalen (king of Leonois) and Blancheflor, the younger sister of Mark, prince of Cornwall. However, his environment made it fitting to call him a "child of sadness".
To begin with, his father Rivalen died in battle without ever being able to see Tristan's face.
His mother Blancheflor died post partum, soon after naming the boy Tristan and entrusting him to a loyal subordinate of Rivalen, Loire.
Bond 3
トリスタンはその後、叔父であるマルク王の騎士として仕えることになった。
トリスタンは良き騎士として王に仕え――王もまた、眉目秀麗なこの騎士に厚い信頼を寄せていた。
しかし、ある時トリスタンはイゾルデという女性と恋に落ちる。いや、落ちてしまった。
Afterwards, Tristan became a knight that served under his uncle, King Mark.
Tristan served the king as a good knight— and the king too had a deep trust in this handsome knight.
But, one day, Tristan fell in love with a woman named Iseult. No, he was made to fall in love.
Eventually, Tristan collapsed due to being poisoned in a certain battle and, on the verge of death, wished to meet with Iseult.
"A white sail if she comes. A black sail if she does not--"
Upon seeing the boat carrying Iseult, Tristan's wife Iseult whispered the following.
"A boat with black sails is coming this way"
The tale of Tristan was put to an end by means of a modest treachery (lie) towards a husband who, despite taking a wife, never tried to love her.
King Arthur was a fine king. Fair, sincere, to the point that his emotions did not crawl in the way of his judgment.
The figure of a king who had killed himself and continued to fight, it was too painful.
It was painful because it was just, it was sorrowful because it was just.
Tristan had no spirit to endure it any longer.
He spouted unexpected words when leaving the Knights of the Round Table.
To all of his brethren—and to the king a curse he gave without him noticing it.
Sorrowfully, he muttered.
He might look like he's asleep, but he's actually awake. Whenever he's sad, he'll play his harp to attack anyone close to him. When he opens his eyes, his cosmos will explode and use a skill that takes away all your five senses.
Trivia
He shares the exact ATK values at minimum with Astraea.
In his Interlude, he mentions Bors and his unfortunate death, decapitated by a "dreaded vorpal bunny". This is in reference to the 1975 film "Monty Python and the Holy Grail", which features such a scene and detail with the Rabbit of Caerbannog. Unlike in the film where Arthur uses the Holy Hand Grenade of Antioch, the rabbit is killed in a joint effort between Gawain, Lancelot, and Mordred.
