Dogmatic Opinion
The word “Toppuri” reminds me of the end of the day.
It seems to mean that the whole thing is immersed in a liquid, but it is predominantly “Doppuri”.
In the sense of change as the sun sets and the area becomes darker, the expression “Sukkari” would mean the same thing.
I dare to describe it as “Toppuri”,
I feel there is a sense of experiencing a scene of the sun setting (similar to the movement of a round object being immersed in liquid).
