Azusa was reincarnated as an immortal witch in another world by the grace of a goddess. In her last life, she died from overwork, so this time she decides to take it easy. She spends 300 years defeating slimes every day to make her living… ​

And before she knew it, she had reached MAX level and become the world’s strongest!​

As rumors of her strength spread, her once-quiet highland home is invaded by lots of different girls: a dragon girl, a slime spirit, an elf, and a ghost, each with their own problems to deal with. Unable to ignore their worries and situations, Azusa rushes to resolve their issues, welcoming them as family and starting a new slow life with everyone. However, this new life might be a bit too lively to be called “slow”――!?​

From visiting hot springs in the Red Dragon’s homeland to attending ceremonies in the demon realm, and even conquering the giant dungeon known as the World Tree…​

Another fun day is about to begin!​
