In her search to destroy the evil Soul Edge, Taki treks to the Lost Cathedral, where she sees Seigfried and Nightmare dueling with Soul Edge and Soul Calibur. She expects the two swords to destroy one other -- but the opposite occurs. A powerful explosion causes the two swords to grow stronger than ever before. Taki barely survives the maelstrom. Later on, she learns that Soul Edge now resides in Ostrheinsburg, and she sets out to find it.
