A Sessy and Rin tribute video. This isn't necessarily a romantic paring video. but it is mostly about Sesshoumaru's feelings for Rin, and highlights how much he's changed since meeting her.
[Sources]: Mostly from ep 162 and the first movie. Also the ep where Sessy met Rin, and when Sessy made a deal with Naraku (I can't remember the ep nubers off the top of my head, sry. XD)
