Atou is a hero unit from Eternal Nations, a country management strategy game. She hails from Mynoghra, the game's notoriously difficult civilization to control, known as the "civilization of ruin."
The interesting part comes after Ira Takuto's death and reincarnation. Atou retains full memories of their time together in the game world and becomes fiercely devoted to him, addressing him as "my king." When transported to the new world alongside him, her classification shifts from hero unit to witch.
Physically, she stands out immediately—pointy elf ears and a set of tentacle or spider-like legs that can emerge from her back. These appendages serve as her primary weapons, strong enough to slice through trees and fast enough to deflect arrows. Beyond combat, Atou has an unsettling ability: she can absorb the abilities and memories of anyone she kills, making her increasingly dangerous as time goes on.
