Blut die Schwester (プルート・ディ・シェヴェスタァ, ?) is an oath between blood sisters that is more akin to a special quality possessed by Berserker than a Noble Phantasm. Her prime body, which is the "sense of touch of the Earth", transforms the surroundings into the Earth's environment through terraforming much like how ORT rewrites the natural world around it with the laws of Mercury. This is especially effective within the Moon Cell, which is forced to adhere to the laws of Earth due to normally following the laws of the moon. There is a great gravitational burden induced upon those who stand before her, forcing Servants and Wizards reproduced according to the rules of the Moon Cell under six times the normal gravity, causing great damage.[1] Once activated, she is surrounded by a crimson aura that forms a full, red moon behind her. She then rushes towards the opponent and unleashes a flurry of slashes. It weakens the enemy temporarily afterward.
