Spoiler Alert Spoiler Alert: WARNING! This page happens to contain a lot of heavy spoilers that are all originated from the Overlord author, Kugane Maruyama and his collection of written works. Anime-only watchers and Manga-only readers, please take some time off to reflect it over for a bit before choosing to expose yourself on reading the information below recklessly.

Slimeko (スライム子) is a newly-designed virtual character created specifically to host the Overlord (Anime) and Mass for the Dead official channel.


Slimeko is a young pink-haired girl. She wears black gloves, a belt with a skull, and a corset dress. On her head lies a peculiar top hat that appears to be molded out of a pink Elder Black Ooze. Strangely, her face is emotionless.


Despite her lack of emotion, Slimeko has a cheery personality. She appears to have no racial attachments to other slimes outside of Nazarick, seeing them as below her. Additionally, she is somewhat of a glutton as she likes to sample a variety of delicacies she comes across, be it cooked food or a rotting corpse.


Slimeko, though possessing a visage of a human girl, is actually a slime that can change a portion of her body to look human while her true form resides on top of the girl’s head. Disguised as a top hat, she controls her host like a puppet.


Mass for the Dead Arc

Main article: Mass for the Dead Arc

A slime Mercenary NPC that was summoned using YGGDRASIL gold coins by Momonga to help the main character of the game investigate the surroundings outside the Great Tomb of Nazarick after the Mirror of Remote Viewing detected a human village that was attacked by Chaos Beasts. Locating a survivor, Momonga dispatched the homunculus protagonist and Narberal Gamma to find the survivor and interview him. The slime assisted the duo in exploring outside Nazarick after the [Gate] transport was affected by the close vicinity of a Rift, throwing them off course and helped to detect various foes such as wild slimes. She eventually adopted the name Slimeko for convenience sake, which was a dead giveaway for her race and decided to use the alias Surako while in public. After encountering a pack of rabid wolves, she was protected by Narberal Gamma. Slimeko then assumed a more human appearance to better blend in with human society.

Abilities and Powers

Slimeko has the ability to control humanoid bodies which acts as a means of interacting with others. Her acid is not very strong and the combat ability is not high, but it has the mimicry ability. She has the ability to tell the location of the enemy whereabouts. She can do [Message], though it requires a lot of energy to use.[1] In addition, she has a special skill of the slime type, the ability to store information by touching things, and the ability to mimic other beings based on that information.[2]

Solution Epsilon

Slimeko considers herself an idol in the slime world and can't help but compare herself to the other slimes. When she finally meets Solution, she is thrilled and giddy around her.
