PriPara doujin I found in the all-ages section of a Toranoana. It's 15+ and there are boobs. I decided to buy and scanlate this when it caught my eye. It's pretty cute and funny. Link to the creator's website.
Status update: I've been in Japan these last two weeks, hence the inactivity. I will be doing Idol Time PriPara with timing and TS assistance unless that falls through. Hopefully I'll be able to get up to date with current-gen PriPara first.
