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
He sure does. As far as I can tell, Manji has
an assortment of 12 blades. These are comprised of: 2 katanas
(these are the ones he has at his waist), 1 fork-bladed sword,
1 small knife, 2 long-bladed swords (fitted with secondary blades),
1 small knife with a hooked blade, 2 sickle-shaped weapons connected
with a metal chain, 1 long blade with hooks, 1 long blade with
points, and 1 short blade.
