I tried experimenting with using Nina-chan's idea of "everything is reversed inside shadows" to replicate Oborozuki until the sun went down, but in the end, I couldn't make Oborozuki work.
After all, Oborozuki is a spell that combines multiple Silveit threads.
The concept of reversing that didn't quite sit right with me.
So, that day ended with nothing but trial and error.
No real progress was made.
But honestly, that's how it usually is when I try to create a new spell.
For simpler spells like Attribute Change or Form Change, it's different, but complex spells that combine multiple elements aren't something you can come up with in just a day.
It takes many attempts before you finally succeed.
On the plus side, I did get better at catching the mannequin when it flew into the air.
