Britomart (First Ascension) (Fate) Wiki

Britomart in her First Ascension armor from Fate/Grand Order. Unlike her other two Ascensions where she wears skimpy clothing, here she dons a full set of large indigo armor with a horned helmet and glowing orange visor.

This ascension is used for the depiction of her mother as the Avenger-class servant Britomart Alter in the Id chapter.
