Slimeko
Slimeko in Overlord: Mass for the Dead is a pink slime who puppets a molded human-girl body from her top-hat form, summoned by Momonga to act as a guide.
Overlord: Mass for the Dead frames its story through an original guide character named Slimeko, a mascot designed to host the game's official channel alongside the anime. Within the story she is a slime mercenary NPC summoned with Yggdrasil gold coins by Momonga to support the game's protagonist in scouting the world outside Nazarick.
Her true body is a pink ooze shaped like a top hat; by pulling herself inside out she molds a facsimile of a human girl and rides atop it, steering the emotionless puppet from its head. Cheerful despite the blank face she wears, she is a glutton happy to sample anything from cooked delicacies to carrion, holds no attachment to slimes outside Nazarick, and adopts the public alias Surako when the name Slimeko proves a giveaway.
