Himari's true ability is kinda hax. It's also interesting to know that his form changes depending on the master. Unfortunately, there are only two people capable of being his master. I wonder how the author is going work around this limitation to give him other forms in the future?
Anyway, that aside, I look forward to seeing the tsundere get conquered. Ecchi and tsunderes are historically known to be a very good combination, so their interactions shouldn't disappoint.
