From its appearance, it was an antique chariot with two prows. War horses were not yoked on the shaft, but handsome bulls with muscles rippling like waves. Their hooves ploughed the empty space, pulling the luxurious and splendid chariot forward.

No, the chariot was not merely floating in air. Its wheels boomed loudly; it was not solid ground but lightning that the bulls stood upon.

Every time the bulls' hooves and the chariot 'stomped' upon the empty sky, violet lightning spread like a web, rolling the air upwards with deafening roars. The prana spurting from the lightning was probably what Lancer and Saber can only unleash if they use up every single ounce of their strength.
