We've got a grimoire for "magic that displays some kind of number above your head".

It's hard to say what the numbers are because they're so faint...

That's the important point.

Oh well, it's kind of interesting.

Hmm... What is it?

...Oh? It increases.

I recently adjusted it again...

Maybe it's the number of times you've failed to cast a spell? Because I never failed.

I see, as expected from Frieren-sama.

Um...

Only I have the number...
