For Firo’s legs, it doesn’t even take a day to return to the castle.
At the castle, I would mix medicines or learn magic. Raphtalia and Rishia are also studying magic under the court magician.
For some reason, after the class-up, Raphtalia has begun to be able to use magic other than Illusion. She has started absorbing new types of magic into her fighting style like a sponge.
But even for her, there is not much she can learn in 2-3 days.
The court mage says that in 2 weeks, she will be able to utilize Dreifach Class magic. I am waiting expectantly. [1][2]
