Ep 16 – “Between Life and Death: Master the Ultimate Technique, Amakakeru Ryu no Hirameki!” / “Sei to Shi no Aida de! Ōgi Amakakeru Ryū no Hirameki no Etoku” (生と死の間で! 奥義·天飛龍閃(あまかけるりゅうのひらめき)の会得)
Seijūrō reminisces about when he first met Kenshin. While they continue training, Kenshin finally proves himself worthy of learning the final technique, in which Seijūrō begins by teaching and instructing him of the Kuzu-ryūsen attack, a technique which simultaneously deals nine strikes to the fundamental targets of swordsmanship. It is then that Hiko proclaims to Kenshin that he must defeat this technique with the ultimate attack. After much worry about his friends, Kenshin finally looks within himself for what he was missing in life and learns the ultimate technique, the Amakakeru Ryū no Hirameki attack, though it pays a high price on the concept of survival.
