"You're here... thank you for coming"

Alterisha from the Magic Academy's Genius Blinker series. Since there isn't much of her in the Manhwa, this is made with only what has appeared so far (Chapter 95).

For scenario creation: Divide your story into two parts. "The Base" is when she's still Professor Meizen's assistant.

In the "Continuation," Alterisha has already revealed the solution to the famous magic formula (with you as co-author) and now has her own school :0.
