Fate/Grand OrderEdit

Tokugawa's World-Changing LabyrinthEdit

Prior the Master's arrival, Lady Kasuga had fallen ill and on the verge of death. Parvati rescued her by fusing them together, allowing Lady Kasuga to co-exist in her Saint Graph. Lady Kasuga deemed this rescue as a sign that she is needed to fix the problem occurring in Edo castle.

When the Master first encountered her, the Master, Mash and Kiara mistook her for Parvati. Lady Kasuga promptly fixed the misunderstanding.

For a large portion of the singularity, Lady Kasuga guides and teaches the Master through the labyrinth.


When it comes to fighting, Lady Kasuga lets Parvati take control of their shared vessel to defeat the enemies.
