Astolfo

One of the Twelve Paladins of Charlemagne In the Charlemagne Legend, he is the son of an English king, and one of Charlemagne's twelve faithful Paladins. Astolfo is known in his legend for being eternally optimistic and completely lacking in sense, and he can be called "curiosity in human form." He is a frightfully unparalleled blabbermouth, prone to speaking on and on until those involved lose all rationality. His hobby of adventuring gets himself mixed up in an assorted amount of mischief.

His appearance is contrary to the legend of being said to be the most handsome among the Twelve Peers of Charlemagne, and though extremely unexpected, it is natural for legends to become distorted. He purposefully dresses "as a girl" because he likes cute things

During his time with Charlemage he was said to be a weak Knight, that being said after every failure and blunder he would pick himself back up

His conversations, through no ill intent on his part, have a way of meandering toward maximum social awkwardness.

Since he has no wish in special to entrust the Holy Grail, his motivation greatly fluctuates depending on whether he likes his Master.

The type who is frankly straight with the person he came to like, regardless of said person being of the opposite or the same gender

Astolfo leaves all hard decisions as a matter for his heart to decide on the spot, take the courses he deems most fit. He does as he pleases without regret, and such obviousness of course would be hard to fathom from anyone other than him.

Astolfo is the sole remain Heroic spirit from the Great Holy Grail War where 2 sides of heroic spirits fought for a wish granting artifact known as the Holy grail around Trifas, Romania

In the Climax of the war, Astolfo Teamed up with the overseer of the war, The ruler class servant Jeanne d'arc, to stop the rogue servant Amakusa Shirou from using the holy grail to enacting a flawed form of salvation

Seig turned into Fafnir and took the Holy Grail to a place beyond man's reach, preventing Amakusa's wish from coming true

Astolfo's 4 noble phantasms are

La Black Luna: A hunting horn that strikes fear into the hearts of all who hear its sound, prompting instinctive escape. Those within its range will be struck with the shock of an explosive sound.

Casseur de Logistille: Inherited from a certain witch, it is a book with the means to shatter any and all magic recorded within it. Though it cannot counter reality marbles or greater magecraft exceedingly close to Reality Marbles to such an extent, but evoking its true name and reading its content makes it a possibility

Trap of Argalia: Lance of the knight, Argilia. Has a golden tip. Killing ability is low, although a wound is inflicted to the leg of the spiritual body, them to fall to their Knees

His Summonable Hippogriff, A Phantasmal Beast that's an "impossible" existence.

Due to being a servant, Astolfo is Extremely super human even if he is a weaker servant

Astolfo is an androgynous-looking adult young man who is fancily dressed. His armor consists of black underclothes that end in a dress and stockings with greaves, gauntlets, and hip guards with a central red stripe and golden accents on top. He also wears black bows on either side of his head and a cape that's white on the outside and red on the inside with a white fuzzy collar. His long pink hair is tied back into a thick, long braid that is longer than his waist.

Astolfo has created many legends as he was an adventurer who flew to all over the world and even reached the Moon in the end. Through his journeys, he had won numerous Mystic Codes such as his flute, his grimoire, and his shining golden lance. Astolfo brought rise to various legends on the back of mounts like a griffin and the famous Rabicano, but particularly famous among them is something inconceivable for this world—the Hippogriff.

Although many are the glorious tales of Astolfo, it is said that he has made just as many mistakes. He was continually defeated in riding tournaments, fell victim to many thaumaturgical traps and even lost—in a matter of hours—the reason that he had picked up at the moon. However, Astolfo never faltered; he did not seem to consider failure or defeat as blunders in the first place.

Evaporation of Reason: It is impossible for him to keep secrets. He'll carelessly chatter about his team's weaknesses and True Names, forgetful of important things, etc. A kind of extreme curse. This skill also serves as "Instinct." During the battle Astolfo is able to, to some extent, feel the optimal course
