”Power maid and a kobold"... Huh?

RAW says 妖怪や異能者. 妖怪 or "youkai" is generally kept as is in Touhou works since it includes many species of fantasy beings. Besides, Aya is a tengu, not a kobold.
異能者 - I guess you could see "power maid" as "a maid with (supernatural) powers", but that's really weird. Why not go with "superhuman" or even "ability wielder", something like that?

Great translation, love this series.

Not a big fan of this chapter though, Youmu doesn't deserve this :(
In the other chapters the girls have been more than willing... This is the first rapey one.
It seems like the artist might be setting up for him getting punished, though. I could get behind that.

So the order is 1 > 3 > 8 right? Is there anything in-between because I can't see any raws.

1→3→8.

2, 4, 5, 6 and 7 are all Kantai Collection books. All Girlfriend's raws can be found in the galleries.

"Power maid and a kobold"

I don't know if it was a mistranslation or it was on purpose but I laughed
