That Time I Got Reincarnated as a Slime may be one of the quintessential examples of a high quality modern isekai. With its focus on worldbuilding and intrigue, its wide cast of endearing characters and unique premise for its plane-shifting hero, it's packed with plenty of content to warrant its overly long name.
Season 2 of the series wrapped up last September, but even with the upcoming film expected in Fall of 2022, there's plenty of time to fill with other thrilling and creative isekai series. To bide time while waiting for more from Rimuru and the gang, check out the following isekai anime, selected just for fans of the universe's most powerful slime.
The Rising of the Shield Hero: Isekai With Game Elements
The Rising of the Shield Hero is an excellent pick for those who enjoyed the game-like elements of Rimuru's journey. After arriving in a fantasy realm, Naofumi Iwatani takes on the role of the Shield Hero, one of the Four Heroes of legend. However, after being betrayed by the kingdom's denizens and cast aside as a pariah, he loses all faith in other people.
By building his skills and investing in the loyal party members he recruits along the way, Naofumi finds a way to survive and defend the world that rejected him. In addition to having a deeply developed world with plenty of history, Shield Hero recreates the satisfaction of building one's skills from next to nothing. Fans of Reincarnated as a Slime will love the attention to detail in the world's systems and rules while Naofumi finds a way to turn it to his advantage.
Konosuba: The Perfect Isekai Blend of Action & Comedy
One of the best parts of Reincarnated as a Slime is how it strikes a good balance with epic action and heartfelt comedy. Kazuma Satou may have the combined power of three advanced class party members on his side, but the fallen goddess Aqua, the volatile magician Megumin and the masochistic crusader Darkness prove themselves much more trouble than help in their everyday adventures.
Konosuba contains one of the most lovable cast of goofballs in isekai history. Walking a tightrope between rip-roaring hilarity and sincere moments of character development, it creates a feel-good atmosphere similar to Reincarnated as a Slime. Still, while it is primarily a comedy, it has plenty of exciting and nail-biting battles against fierce foes. Likewise, with all its RPG aspects, Konosuba makes its audience feel like they're growing along with the cast as it levels up.
So I'm a Spider, So What?: From Weakling to Powerhouse
The most apparent original aspect of Reincarnated as a Slime is its gimmick in taking the protagonist and making them into a seemingly weak beginner monster. So I'm a Spider, So What? does likewise by making its hero into one of fantasy's most frequently fought creatures. Though the latter was met with mixed reception during its run, there's no denying the many similarities between the two series.
After coming back to life as a nameless spider, the being formerly known as high school student Shiraori must figure out how to navigate her new existence. Initially she begins by learning to survive with her new set of arachnid skills. However, over time she masters this way of life and begins to accumulate immense powers all her own, just like Rimuru.
Overlord: Isekai With a High-Stakes Power Struggle
While Rimuru usually just wants to enjoy life in peace with those he cares about, he is not afraid to appear formidable when the situation calls for it. Overlord is another anime that navigates the nuance between playing a villain and acting heroically. Following the shutdown of his favorite online RPG, the series' protagonist Satoru Suzuki awakens in the body of his character Momonga to find himself transported to a world very similar to that of the game.
Embracing the role of the character he played, Momonga continues to fulfill his position as an all-powerful force of evil, but continues to perform altruistic deeds in secret. Similar to Rimuru's followers, Momonga is surrounded by a large group of colorful subordinates. Together, they become embroiled in a high stakes power struggle for notoriety and influence.
How a Realist Hero Rebuilt the Kingdom
Reincarnated as a Slime is full of complex relationships and histories between its many denizens. For a series that treats its setting with the same degree of intricate detail, look to How a Realist Hero Rebuilt the Kingdom. Kazuya Souma is brought to a land of swords and sorcery as its hero. Using his civil expertise, Souma becomes king of the nation that summoned him, leading them to political and diplomatic success.
Realist Hero is lighter on the video game inspiration that drives other isekai. Instead, it takes a holistic approach to worldbuilding, creating numerous countries and people groups that interact with each other in a realistic manner. This is a good isekai for anyone whose favorite part of Reincarnated as a Slime was seeing Rimuru as the leader of the Jura Tempest Federation, and is a perfect pick for any strategists out there.
