This is a special drama CD single which was given to those who had
bought all the three OVAs. The Kagura SS enters a baseball competition
of security companies. The drama describes the last part of the final.
As expected, they don't play normal baseball... It's not particularly
well written and too short for the theme. The best thing about it is the
cover illustarion; Maya in the baseball uniform (cute ^_^). Just a
collectors' item, I suppose.
