Irma is a Cleric in service of the Earth Mother Mila at Mila Temple. After defeating Grieth, Irma is freed from a jail cell by Celica and is revealed to have known her mother, Liprica, the late queen of Zofia. She further expounds that Liprica was forced into marriage with Lima IV and later suffered from illness in which she died after giving birth to Celica. Celica starts tearing up while Irma attempts to comfort her, then laments about the circlet belonging to Liprica being missing.
When Mila Temple is liberated, Irma will mention Liprica's circlet once more. Afterwards the Masked Knight will reveal the aforementioned circlet in his possession and bestow it onto Celica, promoting her to Princess.
- In the original Gaiden, Irma was unnamed.
