Does anyone remember the chapter where the Shiga king and the PM first receives the letter from the Saga empire about how Satou helped the hero slay a demon lord and how they sent him a bunch of treasure and rewards for his deeds.

It's a rather minor moment in whatever chapter it's in but it been killing me. I've checked a few chapters I thought the scene might be in but I haven't been able to find it. I know its somewhere in Vol 15.

If you know please tell me.
