Yamato Takeru

A legendary ancient Japanese prince whose story is told in the KojikiWP and Nihon ShokiWP. He has sometimes been called "Japan's King Arthur" due to similarities in their legends.

Takeru is the child of Emperor KeikōWP, ruler of the Yamato in the late first century and early second century. His birth name was Prince Ousu (小碓命?). After he slew his brother Prince Ōusu (大碓皇子?), he was sent away because his father feared his bloodthirst. Ordered by the Emperor to kill those who refused to submit to Yamato rule, he was given the sword Amenomurakumo-no-Tsurugi, which had long ago been retrieved from the monster Yamata-no-Orochi by the god Susanoo-no-Mikoto. One of the enemies he defeated gave him the name Yamato Takeru, meaning "the Brave of Yamato".

Takeru killed men and gods in his adventures. In one famous tale, Takeru dressed as a woman to infiltrate a party before killing everyone there. In another story, he used Amenomurakumo-no-Tsurugi to create powerful gusts of wind and put out a fire in a field. Takeru lost his beloved wife Ototachibana-hime on the night of a storm, when she sacrificed herself to quell the rage of a sea God.

Outcast by their family, friendless, and bereft of their beloved wife, Takeru slaughtered people, kings, and even gods as they continued along their path.[4]

At the end of their life, Yamato Takeru died from poison after battling the god of Mt. Ibuki. Their sword Amenomurakumo, eventually renamed Kusanagi, would go on to become one of Japan's three imperial treasures.

After their long journey of conquest, their loneliness growing with each battle, Yamato Takeru's spirit became a white swan soaring through the heavens.[4]

Personality:
Yamato Takeru in the Fate series (primarily as the Saber-class Servant in Fate/Samurai Remnant and Fate/Grand Order) is a powerful, tragic hero characterized by a blend of dignified nobility, combat genius, and surprising cuteness [1, 2, 3].

Personality

• Combat Genius yet Naive: They possess combat power far beyond human limits but exhibit a "Saberface" persona that alternates between intense pride and moments of bashfulness. [1, 2, 3]

• Androgynous & Unbothered: Takeru's true gender is canonically left ambiguous (never corrected). People often mistake them for a woman, which they do not mind, as they used cross-dressing as a tactical advantage in myths. [1, 2, 3]

• Affection for Peace: They express a deep appreciation for the peaceful streets of Edo, finding profound joy in everyday things like delicious rice, which they view as a laudable symbol of peace. [1, 2]

• Growth: Initially, Takeru acts proud and distant, often regarding their Master (Miyamoto Iori) as a "powerless weakling," but their shared conflicts lead to a deeply changed and respectful partnership.
