You legitimately rot my brain cells.
Again, it's 20 chapters in. Kubo wants to make it a point that Soul Society is ****ed. Thus, he can introduce the Royal Court Guard.
The Quincy's powers have already been explained, each Stern Ritter has a letter ascertaining to their ability, (ex: As Nodt is F for instilling and manipulating FEAR, Driscoll is O for OVERKILL). Plus you've seen their multiple forms via ****ING KIRGE EARLY IN THE ARC. You should already know why they are attacking Soul Society. What the **** are you reading.
So don't say you want a description of their powers and what their drive is. WHEN THEY HAVE ALREADY BEEN STATED YOU INBRED.
Please stop reading this series.
You don't deserve to.
