A water wheel powered by oil...?
Wonder where this B-plot is going to go. Is the nee-san going to join the harem? God, I hope not. It's already getting excessive.
You can't just fucking end on a note like that and expect me to take this seriously.
Then again, I guess if it was trying to be taken seriously, it wouldn't have had the dumb vibrator gag.
Awww! This chapter was adorable. My goodness. It's really nice to have that sort-of fanfictiony vibe with these characters and still maintain the general humor of the series.
Poor Yuu. A ghost harem which never shuts up. Truly, the most cursed of fates.
