Ruri

was a character that appeared only in InuYasha the Movie: Affections Touching Across Time, one of the two loyal servants of the main antagonist of the movie, Menōmaru. She fights with a spear and has the power to copy abilities. Upon meeting Miroku and witnessing him using his Kazaana, she copied the power, not knowing much about it or how it worked. Throughout the movie, she and Miroku battle almost exclusively each other, up until their final battle at the Great Tree, when both of them opened their wind tunnels and nothing happened, as the strength of their two Kazaana were equal. So, in an attempt to win, Ruri uses her spear to cut a larger hole in her hand, apparently making her Wind Tunnel stronger. However, it grows out of control and she is sucked into the void, her last words calling out for Lord Menōmaru's help. Miroku then reflects on how the same fate will befall him someday if he cannot defeat Naraku.

In the same way that Hari is a foil to Sango, Ruri acts as a foil to Miroku, since she attempts to use the wind tunnel but doesn't know how to control it. Also considering that they both fight with a staff/spear-like weapon.

She dies from stabbing her hand with her spear making the wind tunnel larger, unfortunately this leads to her being sucked into her own wind tunnel. This occurred when she was battling with Miroku over who would be sucked into each others wind tunnel first. She stabbed her hand to make the wind tunnel larger, but only caused her own demise.
