Description
Solution Epsilon is a slime-type battle maid within the Pleiades Six Stars, the combat maid squad serving the Great Tomb of Nazarick. Created by guild member Herohero, her core function involves acting as Nazarick's final defensive barrier, tasked with delaying intruders until guild members could ready themselves in the throne room.

Physically, Solution typically manifests as a blonde woman featuring spiral curls, blue eyes, and attire emphasizing sex appeal, particularly a maid uniform designed to open easily for victim absorption. As a slime, she wields the racial ability to alter her appearance at will and is noted to rival the Re-Estize Kingdom's Golden Princess in beauty.

Her personality merges predatory instincts with logical pragmatism. She perceives humans as food and toys, deriving pleasure from swallowing them alive to savor their suffering. To lure prey, she often uses her appearance as bait, exposing her chest to attract lustful men before absorbing them. Despite this cruelty, she demonstrates rational thought, frequently criticizing inefficient behaviors in allies like Sebas Tian or Entoma Vasilissa Zeta. Her loyalty to Nazarick is absolute, driving her to independently report or oppose superiors like Sebas if she believes their actions endanger Nazarick, as seen when she contacted Ainz Ooal Gown regarding Sebas's unauthorized healing of the human Tuare.

Solution's chronological activities encompass intelligence-gathering operations in the Re-Estize Kingdom, disguised as a spoiled noblewoman alongside Sebas. During this mission, she devoured the human Zach after receiving permission from Shalltear Bloodfallen. She later participated in Demiurge's false flag operation during the Jaldabaoth incident, masquerading as one of the demon maids attacking the kingdom. At Ainz's grand court, she requested human virgins to consume but was granted captured criminals instead.

A notable deviation occurred when Solution kidnapped Ainz's bathing attendant, the slime Miyoshi, motivated by jealousy over his proximity to Ainz. She concealed Miyoshi within her body, triggering a Nazarick lockdown. After confessing under pressure from Yuri Alpha, Solution explained her desire to assume Miyoshi's duties. Ainz declined, citing her status as a "daughter" of his friend Herohero, but did not punish her, instead acknowledging her initiative.

In the non-canon game *Mass for the Dead*, Solution was among the NPCs killed during Nazarick's transition to the New World. Revived by Ainz, she suffered level loss and participated in missions investigating dimensional Cracks and combating Chaos Beasts. She also contributed to Demiurge's Throne of Death project by consuming a human after skin harvesting.

Solution appears in comedic spin-offs like *Ple Ple Pleiades 4*, where she and other Pleiades work in a bar to practice human interaction for the Sorcerer Kingdom's expansion. Her inclusion in crossover media like *Isekai Quartet 2* also lacks substantive character progression beyond participation in the premise.
