Blade of the Immortal FAQ :

4) Why's Rin so obsessed with Itto-Ryu anyhow?

Well, the entire basis of Blade's plot revolves around Rin's vendetta aginst these swordsmen. When she was only fourteen years old, Rin's father was murdered and her mother raped by Anotsu Kagehisa and his followers (the Itto-Ryu). Rin then swore she would avenge her parents' death and has been looking to do so ever since.

5) Manji looks like he's got a lot of them weapons, ne?
