In order to pick up flagging ratings, the Excel Saga writers introduce a new character: the android lady Ropponmatsu, creation of Dr. Shioji, a brilliant scientist with a mostly-innocent (thank goodness) fixation with small girls. Iwata, of course, becomes hopelessly enamored with Ropponmatsu, completely clueless to the fact that she's not a living, breathing human. Meanwhile, Excel and Hyatt manage to bungle a seemingly simple mission to deliver a package with a bomb in it, one discovered and disarmed by Ropponmatsu... well, not quite, much to Iwata's horror.
