Taira no Kiyomori - Season 1 Episode 3 Son of Two Clans (源平の御曹司)

Heita, renamed as Kiyomori, spends days fighting against pirates in the Seto Inland Sea and restoring stolen food to fisherfolk. Kiyomori, however, is mistaken as a pirate and sent to Kyoto where he is reunited with Tadamori. Although Tadamori tries to place Kiyomori to guard the Imperial Palace, Kiyomori refuses it saying he wants to live his own life. One day, Kiyomori is called to stop by a man named Minamoto no Yoshitomo, the son of Tadamori's longtime foe Tameyoshi, who later becomes Kiyomori's lifelong rival. Yoshitomo challenges Kiyomori on deciding which of the Minamoto clan and the Taira clan is superior to the other by comparing their horseback riding skills.
