Abridged version of 'From Tasofro's blog'
Nitori is less affected by the 'Characters are gradually pulled to the center' mechanic, so it is easier to maintain height difference.
To make use of this property, her weak shots move in a parabola, and her strong shots shoot up and down, and she can't shoot directly in front of her.
She has a 999 battery count for her skills and shots.
While it lasts, spirit consumption is low. But when it runs out, attacks might weaken, become unusable, and/or use more spirit.
Tasofro also mentions that Nitori has lots of skills with ZUN's naming sense. (The skill in the screenshot is called 'Photon Torpedo')
Of course, This isn't the whole post.
I think ZUNnaming is awesome.
I'm still quite sure that Nitori has her battery refilled for the next round.
I also except someone like Rin or Koishi.
