Those ribbons of her's soon formed into a giant cannon, pointing down at the Witch. Mami hadn't planned for things to do like this, but with Rin's help, taking the Witch down didn't look to be all that difficult. She summoned up all her strength to load that giant gun, yelling out, "Tiro Finale!" as it fired.

The entire inside of the barrier shook as that giant rifle fired. In an instant the entire train body of the witch was disintegrated, leaving behind nothing except a little black gem.

"Thanks for your help, Tohsaka-san.." Mami wasn't happy about how things had gone, but the Witch was dead, and she got a Grief Seed to purify her gem.
