Ikai no Himemiko wa Pâtissière

Synopsis

One day, Emi, an apprentice pâtissière, suddenly found herself in another world where evil spirits were abound. As she was about to be attacked by a beast, she was saved by a handsome knight. She makes some pudding to thank him, and by chance it was discovered that the sweets made by Emi were able to purify evil spirits! Dumbfounded by this, a shrine was set up in her name and she became known as the legendary purification princess?! (Source: AlphaPolis, translated)
