## Synopsis

I've Been Killing Slimes for 300 Years and Maxed Out My Level (2021-2025) is a Japanese animated isekai comedy adapted from a light novel and aired on AT-X. After dying of overwork in the modern world, a protagonist is reincarnated as an immortal witch who spends three centuries in a quiet, self-sufficient life, hunting slimes to pay the bills. Her unhurried routine gradually builds a reputation, and she reaches level 99 without ever meaning to. Rumors of the powerful witch draw curious adventurers, a duelist dragon and a monster girl who insists on calling her mom, all of whom disrupt the peace she wanted. The engine of the show is this gap between a protagonist who craves calm and a world that keeps pressing in on her, and each episode is built from small domestic mishaps, deadpan exchanges and the escalating attention of strangers. Told across two seasons and twenty-four half-hour episodes, the series keeps a gentle, cozy register with light fantasy wonder and self-aware humor. Its relaxed pacing and low-stakes charm will appeal to viewers who enjoy the comfortable energy of slice of life anime. Fans of That Time I Got Reincarnated as a Slime, Mushoku Tensei and Frieren will find familiar pleasures here.
