@@RakuUshio Unfortunately, unless you come to japan and go in used doujin shops, it would be really hard right now since they have been inactive for the last 3 years. I couldn't find any place online to buy them by a quick search.
There's still some available in used shops in japan, but yeah, since the band is pretty much gone now, it's hard to find their stuff. Their website has not been updated in years :(
