I know Ser technically hasn't discovered her first release yet, let alone made her way through the Academy, but I just had the urge to doodle in my boredom this morning after Jordan and co. left the recruit room for the night.
It's name is Saidosha (or Redeeming Warrior if my net buddy's to be trusted on his Japanese skills), and I'm figuring its ability will involve being able to land an attack two or three times in a single swing since it's otherwise a bit cumbersome to wield for her (or will be at first) and thus easy for speedier folk to dodge.
Haven't even thought about Bankai yet, but.. uh.. that could be scary.
