I've Been Killing Slimes for 300 Years and Maxed Out My Level

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 shes 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...

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 Witchs House, was born. Will the villagers enjoy this little shop Azusas family has created?

Azusa takes Falfa and Shalsha to the World Spirit Conference. When they return, Beelzebub asks for a favor.

Azusa learns that mandragoras gain the ability to walk and talk after 300 years, so she goes to find one.

Laika enters a martial arts tournament to help Fightie, whos hoping to win the prize money.

Azusa takes her family to the ocean, where they meet a jellyfish spirit who also happens to be a painter.
