Another isekai centered around a group of lovely ladies. You want me to watch an isekai, that is the best way to get my attention. That or say there is yuri. This one features both. Question is whether it is worth checking out. Let us find out as we take a look at “Ive Been Killing Slimes for 300 Years and Maxed Out My Level”.
Alternate Title: Slime Taoshite 300-nen, Shiranai Uchi ni Level Max ni Nattemashita (Japanese)
Genres: Comedy, Fantasy, Isekai, Slice of Life, Yuri
Number of Episodes: 12
Plot Summary: Ordinary office lady Azusa Aizawa died due to overwork. For that reason, when she finds herself reborn as an immortal witch with the appearance of a 17-year-old, she decides to live an easy-going life. Her main source of income is collecting magic stones that drop off the slimes that live in the nearby forest and selling them at the nearby village’s guild. After doing this for the last 300 years, she’s unknowingly become a level 99 witch, the most powerful of all.
The above plot summary is summed up nicely in the first half of the premiere episode. It also mentioned Azusa passed away due to overwork in her past life. I mention this this early into the review because there are certain episodes that feature depictions of things/events similar to “our” world with themes or messages that hit home to people in the workforce and even fandoms or conventions. Most of the show is about Azusa’s many adventures to various places helping people along the way and of course adding ladies to her family semi harem. We will get to that later.
Best way to describe the show is with one word, fun. Watching “300 Years Killing Slimes” to me felt like watching Kuma Kuma Kuma Bear. That is how I got someone to give it a go. This show has similar vibes. This is no isekai about a reborn human destined to save another world, rather one about a human getting another chance to live a better life than her last and making the best of it.
Sure there are some disputes she must qualm and big enemies to overcome once in a while but mostly it is a lighthearted romp with occasional vintage isekai battles, meaning the OP protagonist one hit KOs most of her opponents leaving everyone with their jaws on the floor. The combat remains the least interesting part of most isekai I pick up because most of them feel copy/paste to me. Nothing against the OP protagonists. It is just I have seen this so many times in isekai up to this point I need something extra special to make me care about a battle in shows like these. For viewers who enjoy this setup however, expect to see a lovely witch with a nice balanced body making intimidating foes look like puny New Jersey hobos.
Besides going on cracker jack adventures and expanding her family the other important part of the show is said family. The girls who choose to stay and become part of her life all help make her a better person. Not that she was not a pretty cool and helpful witch already to the local townsfolk the past 3 centuries but the newcomers who join her, some “Nanoha Style” and others through less violent ways, expand her outlook on life, giving her more to care about and live for. The above children for example help show her the wonderful world of motherhood while the redhead is someone I will get to in a bit. Other “relatives” fill roles such as the cool aunt from Toronto or the crazy disaster cousin from Montreal, each showing her the value of spending the rest of her life with other people, basically show her the pros of starting a family. Some minor cons also but mostly pros.
Of course this being an isekai in a fantasy setting expect to see some cool sights and references to other fantastical things such as the mythological world tree. There are RPG elements but surprisingly not as many as I expected. They were kinda dropped early or not really emphasized much as the show progressed. Fine by me. Not every fantasy isekai needs RPG references.
The presentation is solid. Ladies all look cute and/or sexy, the action is nicely animated and the setting has familiar but nice locales. An isekai with chill vibes needs to show viewers the world characters tout as being pleasant to live in is not just them exaggerating. It should look like a neat world to live in. This show accomplished that. The soundtrack is solid too with a fun OP that kicks in a couple episodes in funny enough. The ED is nice and chill. Oh and some effects voiced by most likely the other characters, such as surprised reactions or breast physics in action, was another nice touch. Some scenes even indicate our heroines may be aware of the voiced sound effects. That or it really is them providing their own sound effects.
Time to explain what I meant when I said “family semi harem”. Some of Azusa’s family members would gladly eat her taco if she let them, except her precious children obviously. Her “close enough” future wife, cool aunt from Toronto, crazy disaster lesbian cousin from Ontario, second cousin from Los Angeles, all open to consuming a Level 99 cuisine. Other ladies outside her family also have a craving for witch salad. In particular a certain ruler with a love of pranks. All kinds of cravings from “Please pat my head as I lie on your sweet lap” to “Giveth me thine boobies!”. Heck the reason Azusa got the second life deal was a yurirific one.
Overall “I’ve Been Killing Slimes for 300 Years and Maxed My Level” is a real fun time. Nothing more, nothing less. Vintage OP isekai protag battles aside it is a show full of laughs, some interesting themes and a wonderful protagonist with her family of cuties and hotties. The presentation is nice and the yuri cravings vary from sweetness to “FEED ME!”. Magical good time for all interested, yes.
Speaking of KKKB, I THINK 300 years has less of a “children’s cartoon” vibe to how problems are solved compared to bear jammies girl. Personally did not bother me but some pointed the “simplicity” of the KKKB anime adaptation as a con. This one PROBABLY stuck to the source material more. Ask Rory about that. His gleeful approval and NEED for a second season are indications it did. I would happily accept another one also.
