And here's the (most likely) final Christmas release, Haganai volume 4 chapter 8. Dunno where the person who was typesetting the fourth release went, but perhaps it'll just end up delayed until New Year's or something. Anyway, enjoy the end of your Christmas (if you live in one of the GOOD timezones, tehe~) with the links below:
P.S. - The random vol 5 chapter is of similar quality to the vol 7 ones. That is to say, not that great; especially when you're mistranslating train as bus.
