Achetto is a Ptolemaic Army cultist and one of Mira's subordinates; she was experimented on by her and given immense strength as a result. Even Yoshino admits that she outclasses her in pure strength. She wields a massive battleaxe imbued with magical energy, and as a result of using it for so long her hands are also corrupted by it. Originally she had a purple uniform, but Mira later decided to hand her a lime-green version of her uniform. She's fanatically loyal to Mira.
