One interesting thing about Release that Witch is that it never shows us the main character's previous life. It never tells us that this character is from Earth. It never explains how he ended up in this world or anything like that.
All we see is that the Prince seems to have forgotten who he is, and now he's suddenly a lot more serious than he used to be.
We see very early on that this is a fantasy world, there characters with supernatural powers, but the Prince does not seem to be one of them. He doesn't even believe supernatural powers exist until he witnesses one first-hand.
Then we see a scene of him eating with chopsticks, in a clearly European themed fantasy setting that's otherwise fairly accurate. Did they just not care enough to give him the correct eating implements? No, a short time later another character mentions that the chopsticks are unusual.
We see the Prince up late at night writing and drawing, we see a glimpse of what he's working on - hold on, is that a diagram of a flintlock gun?
And the fire-bending witch he hired is not training to use her powers for combat, instead she's in a smithy practicing to cut and weld metal?
This show uses the principle of show, not tell, to communicate:
This is an Isekai
This character is going to make full use of that
His enemies are going to be so screwed
