As of the time of this writing, it is currently uncertain whether I've Been Killing Slimes will be renewed for a second season. However, if it is, there are a lot of high expectations. From the desire for more epic combat scenes to various relationships developing, fans hope that these dreams will come to fruition in another season of the anime.

10 More Battle Scenes Will Show The Characters' Skills

I've Been Killing Slimes featured a few epic combat scenes, particularly between Azusa and companions and foes like Beelzebub and the Demon King herself, but even more battles would make the second season even better.

Many especially enjoyed watching Azusa and Beezelbub's battles against each other, since despite Azusa being overpowered due to being a typical isekai protagonist, Beezelbub didn't make it easy for her to win. Having more combat scenes would also give other characters such as Rosalie, Falfa, and Eno possible opportunities to show off their skills.

It was established in the first season that the red and blue dragons lived in separate clans and even fought each other - until Azusa finally forced them to sign a peace treaty after the blue dragons crashed Laika's sister's wedding. However, some fans are curious about whether there are other dragons and dragon clans to get to know. Many also wonder how the peace treaty between the clans is going overall; are they adhering to the treaty and living better lives, or are there more conflicts that need to be solved first?

While some want to see more of Laika and Falfa's dragon-related connections, others want to know more about Shalsha and Falfa, the two slime spirit girls. They were introduced in the second episode as being daughters of Azusa due to Azusa killing so many slimes in the past for XP and money. However, it raises the question of if there are other slime spirit people that exist thanks to Azusa. Fans also want to learn more about Falfa and Shalsha's magical abilities, since Shalsha nearly beat Azusa in her debut episode with them.

Either way, it's expected that Halkara will have more accidents both on the medical and mushroom-related side, considering all the accidents she made during the first season.

Rosalie was introduced partway through the first season as a ghost and even possessed Halkara temporarily during her debut episode. Fans loved Rosalie after she used her skills to help the main cast with running the café during the season finale, as well as other situations.

However, her presence had fans wondering if Rosalie is the only ghost that will be present in the series, or if there will be more. Considering the plethora and variety of supernatural beings already encountered so far, it's likely there will be more ghosts moving forward.

3 More Sweet Tunes From Kuku In Season Two

Kuku was introduced late in the first season, where she struggled with her music career due to the lack of authenticity she had with herself as a musician. After receiving help from Azusa and her friends, however, Kuku's career took off and she even returned in the season finale to help out with the café.

Fans loved Kuku's new music and want to hear some more songs from her if she returns in the next season. Considering how well she also bonded with Flatorte, the blue dragon, their friendship could use some more screen time as well.

2 A Return Of The Demon King

The Demon King, also known as Pecora Allieres, was amusingly cute and powerful, and her desire for a sisterly bond with Azusa was charming. Even though she almost had Halkara executed, Azusa and the rest of the cast eventually moved past it. Pecora even returned in the season finale to help out with the café as another waitress. Fans are interested in Pecora returning in the next season in some capacity, especially for the sake of showing off her fighting prowess as a powerful demon.

Whether they will or not is unknown, but it's true that they have the closest bond in the series so far. Their friendship together is one of the most memorable in I've Been Killing Slimes, and a second season would give them the opportunity to get even closer.
