Angel Sphere

Time to learn a little bit about the abilities of Octavia, the Queen of Hearts!  So, I've mentioned the Roboris Atomos in the past, but here a refresher course. Considered to be the "trump card" that sets a queen apart from even the most skilled warriors, the Roboris Atomos is an ability that is inherited when a queen pledges her soul in service of her dominion.  Of course there are some other critical nuances, but we can delve into those another time.
As for Octavia, her Roboris Atomos is known as Angel Sphere.  Once activated, she is able to manipulate her aura as she sees fit.  She can use it to block enemy attacks (as shown), strengthen her own attacks, walk through the air, and accelerate her movements to blinding speeds.  As awesome as it sounds, there are drawbacks. For instance, to protect one area, she must leave another vulnerable. Because of this, pinpoint accuracy is a must.  However, the Queen of Hearts is well trained, and is considered to be the most well rounded fighter of the four.
