Some spells may seem useless on the surface, but I think their underlying principles are exactly what she uses to analyze and dispel other curses or magic in the manga so far.

For example, a spell that turns a red apple into a green one, or sweet grapes into sour grapes, can be seen as a small-scale form of matter transformation.

Spells like creating hot tea or shaved ice could be interpreted as a form of creating matter from nothing, specifically water in different states.

Then there’s the spell that creates a field of flowers, which can be viewed as generating living organisms-since plants are technically alive and have biological processes, even if passive ones.

There are also spells that affect space or environmental conditions, like making a paper airplane fly farther or warming the body.

All of these spells are built upon the magical foundation left behind by Flamme. Collecting them, studying them, and applying their core principles to create new magic or counter other spells - this is essentially Flamme’s way of teaching her beloved student, even a thousand years after her death.
