I want to enter Roka ending and following this guide to achieve that.

But it seems I keep failing to activate the quest of "貢物 Quest completed for Niu".

Is there any specific trigger for this?

BTW I would like to know is it a requirement for entering the Roka ending, or can I simply 'balance' the power by utilize the quest of "復活祭を安全に, 三色染料, 峰霊魚の奉納,古神樹の実,失われた物資 " appear at chapter 4?
