The name is "Twilight/Morning Star Equipment." This is also a play on words with Venus.

This is the previous base body with the armor attached. Parts from Reginglaze Julia, Dantalion, Barbatos 5th Form, and Kimaris Trooper have been added.

This is the rear booster stored state. The legs of Reginglaze Julia have been modified.

I forgot to take a picture of the back in the deployed state...

It stands on its tiptoes during space combat.
