４. Story Overview (No Spoilers)
After dying from overwork in her previous life, Azusa is reincarnated as an immortal witch in a peaceful fantasy world.
Determined to live a stress-free life, she settles in the highlands and spends her days casually hunting slimes.
However, after 300 years of this routine, she unknowingly reaches level 99, becoming the strongest witch in the world.
Despite her efforts to maintain a quiet life, word of her strength spreads, attracting all sorts of visitors to her doorstep—a fiery dragon seeking a master, twin slime spirits who call her “Mom,” a clumsy elf entrepreneur, and even a high-ranking demon lord.
In Season 2, Azusa’s peaceful life gets even livelier as a new character, Sandra, a mandragora spirit, joins the family.
Alongside new friendships, the story will take the group on a hot spring trip to the Dragon Clan’s homeland, a grand festival in the Demon Lord’s domain, and even an adventure into a massive dungeon known as the World Tree!
