Getting QC applicants can be easy, but having skilled people that actually stick around join is a bit harder. The Koiken Otome project is currently at 86% translated, late enough in the game to make a serious recruiting push for QC.
Quality checkers are expected to both find grammar/spelling mistakes and point out awkward phrasings and sentences. They should do “enough work to know they are not afk”. You will be reading scripts in text form, but also testing them in-game. You will need to do QC work for H-scenes.
Finally, you are expected to use IRC actively. To apply, join #pantsu-vn on Rizon (fitting~).
EDIT: as of 09/09, they are no longer looking for QC as positions have been filled.
