That Time I Got Reincarnated as a Slime stars Rimuru Tempest, the isekai slime hero who seeks not to conquer the world or build a harem, but to found a new nation of tolerance and peace for all monsters. While Rimuru has many magical abilities of his own, what he really needs is allies and friends. Fortunately, he has plenty of them.

Rimuru's closest allies are powerful, skilled, and smart people of all races, from humans and dwarves to ogres, goblins, and even orcs and dryads. Not only are they fierce fighters or skilled artisans, but they are also Rimuru's personal friends. These characters are driven mainly by their fierce loyalty to Rimuru and the friendships they share with him. Who ranks among Rimuru's closest and dearest friends?

10 Gobta Is Rimuru's Goblin Pal

Gobta is a casual friend of Rimuru's, being one of the first people who ever allied with him, and Gobta will do anything for his slime boss and friend. Gobta is a bit arrogant and goofy at times, but he still values his friendship with Rimuru, and he'd rather fight in Rimuru's name than his own.

Gobta is eager to prove himself to Rimuru and show off, and he trained with Hakuro the elder swordsman so he can be of better service. That's what a truly loyal friend would do, and Rimuru is grateful for all the help.

9 Shizue's Friendship To Rimuru Was Short But Sweet

The masked hero Shizue Izawa only spent a brief period of time with Rimuru before her time came, but she and Rimuru did get along quite well before she passed away. Shizue is an isekai heroine like Rimuru, who came from World War II-era Japan. It was Demon Lord Leon Cromwell, in particular, who summoned her here.

Shizue trusted her good friend Rimuru with her beloved students in the Ingrassia nation, and Rimuru honored her memory when he visited Freedom Academy to coach those kids and hone their skills. That's a fine way to pay tribute to a fallen friend.

8 Ramiris Is Rimuru's Tiny But Powerful Friend

Not all Demon Lords are hulking brutes. One of the oldest and strongest Demon Lords is Ramiris, a fairy who crossed paths with Rimuru late in Reincarnated as a Slime Season 1. She and Rimuru clashed at first, but they soon became friends and political allies.

Ramiris is a goofy and hotheaded little Demon Lord who flew all the way to Tempest to warn Rimuru about the Walpurgis meeting and other threats to his ream, which is something only a good friend would do. During Rimuru's battle against Clayman, Ramiris urgently wanted to help her friend, but Guy Crimson didn't allow it. So, Baretta the golem was sent to help instead.

7 Benimaru Is A Key Ally Of Rimuru's

The ogre warrior Benimaru may not be Rimuru's BFF, but he is certainly a loyal and fearsome ally of Rimuru's, and the two of them get along just fine on a personal level. Benimaru may be the ogre tribe's leader, but he puts Rimuru first, and Rimuru is thankful for the support.

Rimuru trusts Benimaru with even the most important and difficult tasks, such as leading an army against Clayman's forces, and the two of them have bonded over their dislike of Shion's terrible cooking. They have suffered together more than once.

6 Shion Is Rimuru's Secretary & Funny Friend

Shion is another member of the ogre tribe, along with Benimaru, and she is fanatically loyal to Rimuru on a professional and personal level alike. Rimuru finds her flamboyant and immature personality tiring at times, but he wouldn't dare kick her out of Tempest. He's glad to have her around.

Shion has all kinds of fun with Rimuru, including dressing him up with Shuna, and she gladly offers him her terrible cooking, incorrectly thinking that she's servicing him a treat each time. In honor of their friendship, Rimuru will sometimes eat what Shion offers, but not always.

5 Princess Shuna Is Rimuru's Sweet Friend

Another friendly ogre is the lovely but tough princess Shuna, the younger sister of Benimaru the warrior. Shuna has been a loyal and committed member of Tempest since the early days, though she isn't often seen in battle. She would rather handle more constructive affairs in her new home.

Shuna thinks highly of Rimuru as a boss and friend, so she is quick to scold him if he acts out, such as visiting that elf lady bar in Dwargon. She also enjoys dressing Rimuru up in fancy clothes, and she dotes on him like a sister. Rimuru's lucky to have her around.

4 Ranga Is Rimuru's Loyal Hound

Dogs are known as "man's best friend," and in this isekai world, star wolves are a slime's best friend instead. Ranga once belonged to a bloodthirsty pack of wolves led by his father, but then he allied with Rimuru and the goblins. It was a wise decision.

Ranga received a name, new powers, and a good friendship when he allied with Rimuru, serving as that slime's faithful mount and enthusiastic friend. Ranga is always happy when Rimuru summons him, and he'll gladly fight any enemy for Rimuru's sake.

3 King Gazel Dwargon & Rimuru Are Close Friends

Rimuru is capable of making friends in high places, and that includes the king of the Armed Nation of Dwargon, Gazel Dwargo. Gazel Dwargo is a patient and insightful king who doesn't rush recklessly into any situation, but once he saw Rimuru's wisdom and strength, he extended the hand of friendship.

Rimuru and Gazel are political allies and friends, and they are even seen sharing drinks together. Gazel also gladly shared advice to Rimuru on being a leader, including how to deliver an effective speech and project power and confidence as a leader. Rimuru listened closely and started applying his friend's vital lessons.

2 Demon Lord Milim Sees Herself As Rimuru's Bestie

Demon Lord Milim Nava is massively powerful, despite her youthful appearance and bratty personality, and she ranks among the strongest—or at least coolest—pink-haired characters in all of anime. She and Rimuru clashed briefly before Rimuru bribed her with food to make her stand down.

Now, the impulsive and whimsical Milim sees Rimuru as her bestie and equal, and she had a lot of fun with him during the events of Slime Diaries. Rimuru is cautious around Milim, and rightly so, but Milim is unlikely to actually betray their friendship. She's scary, but not a traitor.

1 Veldora Might Actually Be Rimuru's Bestie

The powerful Veldora was a fearsome storm dragon who wreaked havoc on this isekai world until the masked female Hero finally sealed him away. Centuries later, Rimuru the slime showed up, and Veldora befriended him, despite the difference in their size and power. Veldora gave Rimuru his name, and allowed Rimuru to eat him with the Predator skill.

Veldora was reborn when Rimuru gave him a humanoid body, and Veldora was deeply grateful for it. He and Rimuru now get along better than ever, and they tease each other and goof off like lifelong friends. In particular, Veldora reads all the manga that Rimuru prints for him, which is how he learned what the Kamehameha is.
