abigail williams (event portrait) (fate)
Abigail Williams in her outfit from the Heroic Spirit Event Portrait collection of Craft Essences, commemorating Fate/Grand Order's 8th anniversary. The FGO news announcement lists it as being her Summer version.
Don't confuse this with her regular Foreigner variant's First Ascension or Second Ascensions, nor her Swimsuit Foreigner's Third Ascension.
