Houjou's ancestor, Houjou Akitoki, shows up back in the past, and he is also in love with Kagome. He appears first in the second movie, Castle Beyond the Looking Glass, and then later in Episode 137: The Ancestor's Name Is Kagome. Houjou Akitoki looks a lot like the present day Houjou, except with a different hair-style and his hair and eye color are a lighter brown. (Source: AbsoluteAnime)
