After a tough life working long hours at the office, Azusa Aizawa finally burns out and dies from overwork. But instead of resting, she wakes up in front of a goddess, who sends her to a new fantasy world where she’s reincarnated as an immortal witch. Azusa, determined to live a peaceful life this time, sets out to find the easiest way to make a living. She doesn’t want to attract any attention, so she starts hunting slimes—the weakest monsters around—doing this every day for years. For 300 years, she hunts 25 slimes daily, gaining almost no experience from them. But after all that time, she ends up leveling up to the max—level 99.

Azusa doesn’t want to stand out, so she tries to keep her newfound strength hidden, thinking that being too powerful will just drag her back into the exhausting life she left behind. But, of course, things don’t go as planned. No matter how much she tries to stay under the radar, rumors about the “Witch of the Highlands” start spreading. Eventually, a proud dragon named Raika shows up, hoping to challenge her. After Azusa defeats Raika, they become friends, but that’s just the beginning of her new problems. As both allies and enemies seek out the mysterious witch, Azusa starts to realize that having friends—people she can call family—makes life a lot more enjoyable than being alone.

When is the second season of the anime?

The final episode of the anime aired on June 26, 2021, leaving fans eagerly awaiting news about the future of the series. On January 4, 2022, fans were delighted to hear that the anime had been renewed for a second season. While anime renewals can sometimes take years, the fans of I’ve Been Killing Slimes for 300 Years and Maxed Out My Level were fortunate in this regard. However, the wait wasn’t entirely smooth sailing. It wasn’t the quick renewal that kept fans waiting, but rather the long production process, which led to a lengthy wait for the new season. Fans continued to fuel their excitement with occasional key visuals, but despite the renewal announcement, three years passed without a confirmed release date.

Finally, the uncertainty ended when the new season’s premiere date was officially announced: I’ve Been Killing Slimes for 300 Years and Maxed Out My Level will return to screens on April 5, 2025! This exciting news came alongside a brand-new season trailer, ramping up the anticipation for what’s to come.

The beloved main cast is back for the upcoming season, but there are some changes behind the scenes. Kunihisa Sugishima, known for his work on the Beyblade franchise and Strike Witches, takes over as director, stepping in for Nobukage Kimura. This time, animation duties are being handled by Teddy, replacing Revoroot from the first season. Naohiro Fukushima, who contributed as an episode scriptwriter last time, will now oversee the series’ scripts, taking over from Tatsuya Takahashi. Fans will also notice a new face in the character design department, with Hikaru Kodama stepping in for Keisuke Goto. On a familiar note, Keiji Inai is returning to compose the music, bringing his signature touch to the soundtrack at Nippon Columbia.

What Can the Audience Expect in Season 2?

Warning: Spoilers Ahead for I’ve Been Killing Slimes for 300 Years Season 2!

The first season concluded on an exciting note, with Azusa opening the door once again, while Falfa prepared for the upcoming dance festival. Azusa, however, chose to establish a café, a decision fully supported by her family, who were eager to transform their Highlands home into a bustling café. The next morning, Azusa wakes up to find a long line of people waiting outside, realizing that her café venture has been an overwhelming success. Beelzebub, Falfa, Pecora, and Vania all join her in running the café. Eager to enjoy the dance festival with her family, Azusa sets out, and the episode ends with her asking a visitor standing at her door how she can be of help.

The series stands out in that none of the main characters are male, and it’s likely that Season 2 will continue this trend. In the upcoming season, we might see Azusa and her family visiting Beelzebub’s home. Shalsha and Falfa could start school, though they may eventually return to managing the café. Laika’s impressive martial arts skills may be showcased in a tournament, and we may also witness another family visit to Halkara’s home. Azusa’s previous disappointment over the World Tree not being a real dungeon will be addressed, as fans can look forward to an actual dungeon visit in Season 2. Additionally, Azusa’s help to a friend will result in an unexpected wedding. Lastly, we’ll have the chance to explore more of Azusa’s powers as she adjusts to her new life, making her journey even more exciting.
