Ladybird

Ladybird (レディバード) is a character introduced in Souyaku Toaru Majutsu no Index.

Equipment
Ladybird wields a 60cm machete known as Left Arm (防御の剣（レフトアーム）). It is made of the artificial element Saintium (セインティウム‎‎‎), which has a metallic bond strength 56 times greater than depleted uranium. As such, the blade can easily stop a warship's armor-piercing artillery and be used to deflect bullets, though it is too heavy for a normal person to wield.

As well as a smartphone on each shoulder, Ladybird has several belts around her thighs with skinny tubes which contain rolled-up silicone keyboards and clear bottles filled with thick, clear liquid. The liquid in the bottles is a discharge machine oil (放電機械油) which reduces the frictional wear on her joints, as well as a room temperature superconductive fluid which allows her to safely release her excess energy
