I don't like when people view Tomoe and Kaoru as rivals. They were totally different people in completely different parts of Kenshin's life. A man can love more than one woman in his life without betraying the memory of one over the other. Kenshin loved them both for differing reasons, and that is what I love about the story: Kaoru helps Kenshin find true peace by disregarding his past and accepting him, teaching him to finally see his own worth as a human being again for the first time in a decade. Tomoe taught Kenshin of a life besides that of a murderer and that one cannot keep on fighting forever. He met the sad Tomoe in bloody chaos of the revolution, and Kaoru in the peaceful times of the Meiji, each woman's demeanor reflecting the era when they met and fell in love with Kenshin.
I like how you did this. Kinda shows how Tomoe was his past with darkness, mistrust, tragedy and bad memories, while Kaoru is his future with happiness and truth and love with Kenshin in the middle connecting the two women.
