After 300 years of this simple routine, she has unknowingly maxed out her level, becoming the most powerful being in the world.
Her immense power shatters her quiet lifestyle, attracting a host of challengers, from a proud dragon to a determined demon. Instead of fighting, however, Azusa’s kind nature turns these would-be rivals into a quirky and loving found family.

After dying of overwork in the real world, I’m reincarnated as an immortal witch, and I spend 300 years enjoying a relaxing life. At some point, though, I end up at level 99! All those years spent killing slimes to make the money to pay the bills gave me a ton of experience points. Rumors of the level 99 witch spread, and soon I’m up to my ears in curious adventurers, duelist dragons, and even a monster girl calling me her mom! I’ve never been on an adventure, but I’m the strongest in the world… What’s going to happen to my relaxing life?!
