Nice to meet you, I'm not an English speaker so I'm using machine translation so I'm sorry if it's hard to read. This point includes a cultural aspect to Japan.
1.The Invisible Knight
If you press Z at the image location, the knight's message will appear.
2.Strange characters
The circled string is written in kanji as "中華街(Chukagai)" and means "Chinatown". So that seems odd to me.
3.Shrine box
When you look at the box behind Shira, it says "donation box," but I think it's actually a "賽銭箱(saisen-bako)" so "offering box" seems more appropriate.
