It was against the Yoma in the Holy City of Rabona. In their cathedral lay her target. In order to complete the mission, Clare's weapon (a Claymore) was unable to be used, having to make her resort to two medium length blades. A boy whom she took along with her job as a 'Claymore', Raki, was also at the scene, only able to hopelessly watch on.

Two young soldiers, Sid and Galk, were also assisting Clare in defeating the Yoma. It was overpowering the three of them. That's when you walked in.
