In episode 4 of Witch of Mercury, in order to harass the main characters during practice (during additional exams)
Mob sprays a “slow-acting shielding spray” on the main camera part of the aircraft
↓
As expected, the main character did not go as he thought he could not see, and failed

However, the existence of this spray is controversial…If you try to search for “delayed paint”, “usage” and “usage” will appear as candidates… I think everyone is interested. What is the paint originally made for? What is this reverse learning straight!

If you apply a slow-acting paint to your body,
He’s naked! I thought I could hide it with paint before the police came 😎
On the other hand, I can’t think of the correct way to use slow-acting paint…— Awai Ryuzaki 🐉 (@awaiflavia) October 23, 2022
I’m thinking about how to use the slow-acting paint, but I’m not imaginative enough, so it’s a harassment joke product…

In the first place, what kind of goods are useless other than slow-acting paints?

Even if you use it for maintenance or as a mark, transparent fluorescent paint is fine, and there is no need to make it difficult to remove the color later, so in the first place, it would be better if the world had the technology to change the color of clothes by operating from a smartphone. There must be, but it’s really harassment That slow-acting paint that I can’t think of other uses for than a mischievous item

The Mercury Witch’s slow-acting paint, even though it’s spray-injected, is too densely painted. , The two of Suremio are cute, so it doesn’t really matter

Witch of Mercury episode 4, when you sleep overnight and calm down, you wonder, “What are slow-acting paints originally used for?”

↓There seems to be something similar in reality
Slow-acting paint is a hot topic, so let’s introduce “clock reaction”

Witch of the Mercury Gundam, I’m getting all kinds of tsukkomi for putting out a mysterious item that I don’t really know how to use… what exactly is this used for?
