Episode 2 of I've Been Killing Slimes for 300 Years and Maxed Out My Level, finds Azusa enjoying the rhythm of her new isekai life. Once, she was an office employee who died from sheer overwork, or karoshi. Now, in her new life as the witch of the highlands, Azusa is cruising isekai easy street after patiently killing slimes every day for 300 years to max out her level and bank account alike. But actions have consequences, even in this charming fantasy world.
Azusa has subverted the OP isekai trend with her easygoing lifestyle and lack of ambition, but thousands of slimes have died at her hands, and they all want revenge. It seems Azusa's lazy days might have to wait a bit longer.
Azusa is slowly but surely building up her new life as the witch of the highlands, from her newly rebuilt house to her friendships with everyone in the local town of Flatta. She also fought and befriended, a great red dragon named Laika. But just when Azusa thinks she's on top of her game, a stranger arrives at the door: a charming little lady named Falfa... who claims to the Azusa's daughter.
Not literally, of course. Once Falfa is invited inside for some snacks and hospitality, she explains that her body and mind formed from countless dead slimes coalescing into a single being. So, by killing so many slimes to max out her XP and money, Azusa caused Falfa to be born. Falfa sees Azusa as her beloved mother, or "Mama," but she's also got a sister named Shalsha, who has a very different view of their pseudo-mother. Shalsha embodies the rage of all those slain slimes and has trained for 50 years to perform Smite Evil magic with Azusa in mind. If Shalsha gets her way, Azusa will pay the ultimate price for killing slimes with impunity.
Sure enough, Shalsha arrives to exact her revenge on her mother, and her Smite Evil magic is everything Falfa said it was. Not even Azusa's powerful tornado magic can take her down, and Shalsha can even negate Azusa's flight magic and bring her back down to earth when she tries to retreat. Shalsha has focused all her Smite Evil magic on Azusa personally, which maximizes its power, and it seems there's no way out. That's when Laika, ever the loyal apprentice, steps in to shield Azusa and launches a counter-attack. Shalsha's Smite Evil magic has zero effect on Laika, and a light tap from Laika knocks Shalsha flat on her back. Score one for the great red dragon.
Azusa isn't the type to hold a grudge, though. She brings her other "daughter" inside the house to help her recover, and Falfa helps talk Shalsha out of revenge once she wakes up. Falfa also reasons that many people kill slimes all over the world, and there's no sense trying to get revenge on them all. Instead, it's much better to appreciate the life that she has, and join Azusa's growing household. Shalsha agrees, and later that afternoon, she finally mentions that there are good and evil slimes in the world, and Azusa had been killing evil ones. Shalsha actually condones the killing of evil slimes and closes the book on her revenge. Instead, she joins the growing cast of Asuza's easygoing fantasy family.
