Sasaki kojirou's info

Sasaki Kojirou is the Assassin-class Servant of Caster in the Fifth Holy Grail War of Fate/stay night anime. He is an irregular Servant that shouldn't exist according to the rules of the Holy Grail War, but Caster's unique nature as a Servant summoning a Servant twists the process.

He is also one of the Servants summoned by Ritsuka Fujimaru in the Grand Orders conflicts of Fate/Grand Order, appearing as both his Assassin-class self and as a Saber-class Servant, Nameless Saber , during his duel with Miyamoto Musashi.

A mythical Japanese swordsman said to have faced Miyamoto Musashi in combat. In reality, the individual summoned as Assassin's true name was unknown, and to be more specific, he never had a true name. Kojirou is known as a master swordsman whose existence is doubted even though his name remains recorded in history. He did not actually exist, so it would be impossible to summon the real thing as a Servant. The person summoned in his place is not a Heroic Spirit, but an existence closer to that of wraiths. If there was to be a database for all of humanity, he is the piece of data that best matches the parameters of Sasaki, so his personality would become Kojirou's personality and his monumental feats would become that of Kojirou rather than his own.

Assassin wields the Monohoshi Zao (The Laundry-Drying Pole), an over five shaku long, 150 centimeter, Bitchu Aoe blade. The length defies common sense, the name being a derogatory nickname rather than a formal title, meaning "That blade is way too damn long to use!" It cannot be called "useful" despite its large range, as almost nobody except Assassin, having a mastery of the sword exceeding the realm of humans, could even wield it. The katana is a longsword not suited to direct competitions of power. It will break fighting off a sword like Excalibur, so he cannot lock blades or compete in strength. He can only parry blows and push the opponent back by attacking their body because the blade is meant to cut with speed and technique unlike western swords that cut with weight and power, making fighting styles between the two mismatched.

Fighting on the temple stairs gives him a higher position than his opponent, and due to the area being a Servant-killing battlefield and having Medea's anti-sorcery defensive barrier, the power of both magecraft and Noble Phantasms are decreased significantly. If the Noble Phantasm being used is not powerful, he will not take a fatal wound. While he would fall to other Servants in an all out death match, he reigns supreme on the stairs of the temple due to most battles having to come down to swordsmanship. The attacker is constantly at a disadvantage because they have to ascend the stairs to reach him, while he does not have to move if he does not wish. He has no need to chase a retreating enemy in a battle of defense, so he has no reason to forsake his advantage of higher ground. His excellent skill and the disadvantageous ground keep the opponent from being able to dodge his fatal strikes as they wish.

Noble Phantasm: Tsubame Gaeshi

Sasaki Kojirou's ultimate attack is the technique that has reached the pinnacle of training and approaching True Magic --- Tsubame Gaeshi. Although it is a Mystery that rivals the Noble Phantasms of Servants, strictly speaking, this is neither a Noble Phantasm nor a magical phenomenon. The nameless martial artist who materialised as "Kojirou" sought nothing but the pinnacle of swordsmanship during his life. He trained himself in pursuit of swordsmanship, and doing nothing but swing his sword. After a long period of time, his technique finally reached another state. A flash from this world, followed by two absolutely simultaneous, over-lapping flashes that disregard the concept of time and space, producing a slash attack that arrives from three different directions. This is equivalent to Zelretch's "Multi-Dimensional Refraction Phenomenon" that transcends speed, dexterity, feint and many other elements. Although with some limitations, a nameless martial artist who knows naught of sorcery or True Magic is able to tread into the realm of the "Second Magic"
