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.
