Hiei's two second remodels.

For her second remodeling, she gains the same modifications as Kongou, replacing her spider rig with a ship-like rig, except that the hairband is turned into hairclips (and have a different design) and she has a shorter haircut.

For the 7th anniversary of the game, she was given a Kai Ni C remodel like Kongou's with all the updates and modifications that implies. Her hair also grew somewhat longer than her base form and her hairclips appear to be connected to each other.
