Ok Gorugo barfing was gross, but then on her head ... as expected from the creator of Gintama! :P But poor kid must have been traumatised after visiting her house.
Design wise Fujieda reminds me of Gintoki (with punk hair), and to a lesser extent Gorugo, Sa-chan.
All in all enjoyable oneshot, even managing to threw in some romance... kind of! :D
