Procellarum Lepus Phantom

Procellarum Lepus Phantom, also known as the Moon and the Phantom Rabbit is a Artificial Ancient Gear that was created by Azazel and specifically given to Ruruko Nimura.

Summary
In Volume 14, Procellarum Lepus Phantom was one of the 6 artificial Ancient Gears given to members of the Sitri group that was personally given to Ruruko, which she later used on a mission to save the first-year members of the Occult Research Club that were kidnapped by the Magician Faction of the Chaos Insurgency.

Appearance
Procellarum Lepus Phantom has the form of a set of armor primarily on the user's legs.

Abilities
The armor can strengthen the power and capabilities on the users legs, granting them an increase in combat performance such as greatly enhanced speed and immensely powerful kicks. It can also leave behind after images of the user to confuse their opponents. In True Volume 5, Procellarum Lepus Phantom has attained time-based powers that makes time move differently from the user, making the people around users move in slow motion and it makes the users possibly faster than Arthur and Sebastian.

Hyper Phantom Rabbit
Hyper Phantom Rabbit (ハイパー・ファントム・ラビット, Haipā Fantomu Rabbito) is the Counter-Drive of Procellarum Lepus Phantom, which now covers Ruruko's upper body in armor as well. In this form, it greatly increases the user's leg strength and speed, enabling her to jump high and move at a rate that was hard for Arthur to track while in his Crimson armor. It also has the ability to deflect and rebound the trajectory of various moves and techniques with a swing of the user's kick.
