This is Requiem in her True Goddess Form. pretty badass, isn't it.

as she is a Goddess, Requiem has a number of different forms. well, only 3. all depends on the sword, Nexus Ultimus, the ultimate weapon that can divide into two swords.

there's her normal, human form, which she's in almost all the time. that's when Nexus Ultimus is in it's scabbard.

there's her partial Goddess form, which is a form that combines her human form and True Goddess form. Her Valkyrie armor appears over her clothes, causing only a few changes. this form is activated when she brings out only half of the sword, Nexus or Ultimus.

there's True Goddess form, which is this form has her clothes replaced with Valkyrie armor. this form is activated when she brings out Nexus Ultimus in it's entirety.

then there's her Final Form, which is unknown. for now.
