So the censored word is around 16 minutes, during the scene where the girls are drunk from eating liquor-filled chocolate and tie Tomoya up to play a prank on him, Tomoya says
What have you done?!
The **O won't be...
I'm not sure what was censored with "**O".
It's likely referring to the BPO, the (Japanese) Broadcasting Ethics & Program Improvement Organization:
A non-profit, non-governmental organization that serves to improve the quality of broadcasting and promote higher ethical standards while ensuring freedom of speech and expression.
BPO deals with complaints and ethical issues by conducting investigations into problematic programs and giving recommendations and/or opinions to either all broadcasters or to the particular broadcaster concerned.
This is one of many meta jokes from this episode.
