Mizuho Itsuki 
Management of a Novice Alchemist: Volume 5 [EPUB ebook] 

Now that Iris and Kate have been rescued from the cave collapse in the mountains, winter has come to Yok Village, and with it, the slow season for Sarasa’s shop. As she and her friends struggle to make ends meet, a customer comes to visit—and he’s royalty! Unable to turn down his request, the gang heads out into the winter mountains on a mission, but the party is attacked by a swarm of monsters and soon finds itself entwined in the schemes of the local lord, Baronet Kahku. With all the new trouble that’s brewing, will Sarasa and her friends make it to spring in one piece?!
