The RM-047 Valvrave IV Hinowa is the second Valvrave to take an active role in the series and piloted by Rukino Saki. Its official name is Hinowa, but is later nicknamed Carmilla by Saki.
Valvrave IV is a high mobility weapon, designed to quickly take out any type of enemy from any range. Using its specially designed Multi-Leg Spine to quickly accelerate or change direction at high speed, it can outmaneuver machines with traditional thrusters, outrun missiles, and even outpace the other Valvraves. It is equipped with the Mirror Rave engine, a replica of Valvrave I's Rave engine.
Valvrave IV's weaponry is considered unique, even amongst the other Valvraves; its Spindle Knuckles can be launched and controlled in mid-flight, allowing them to fly all over the battlefield, slicing through enemies at the pilot's discretion.
