One day, a girl with rabbit ears comes to the village of Flatta. This nameless, unpopular minstrel, who strums her lute fiercely with her bare fingers and sings with a death growl, is known as Schifanoia. When she passes out in the middle of her concert, Azusa is reminded of the sad stories she's heard of young men who moved to Tokyo hoping to make their major debut, but instead turn into job-hopping middle-aged men playing in bands that never make any profit. So she invites Schifanoia to live at the house in the highlands for a while, but when she just keeps making excuses and refuses to see reality, Flatorte loses her patience...

Halkara throws a mushroom-grilling party, or "shroompa" for short, and accidently includes some poisonous mushrooms that cause anyone who eats them to shrink... and Azusa eats one. This leads to everyone ridiculing her—or rather, fawning over how cute she looks. Even her daughters are in on it! Azusa is determined to change back to normal, so after a tip from Pecora, she heads to the World Tree along with Fatla and Vania to find a pharmacist who deals in every kind of medicine. She expects a dungeon with 108 floors to fight through, but...

Festival season has come to the village of Flatta. The festival has been held there for the past 250 years, but as the only person who knows its entire history since it was started, Azusa has distanced herself from it to let the villagers keep their independence. But her family has shown interest in it and seems excited to see it, so she makes up her mind to change the way she interacts with the village tradition... and thus the one-day-only coffee shop, The Witch's House, was born. Will the villagers enjoy this little shop Azusa's family has created?
