Summary
When Mao invites the girls over for dinner, her terrible cooking causes Chibi Dragon to spit out her old maid golem servant from her time as Demon Lord. Discovering that she lost her memories, Mao takes in the golem, who is given the name Meigo, so she can keep an eye on her. Rona brings a Cartado to restore Meigo's memories but instead restores Yusha and the others' memories of fighting the Demon Lord and getting sent into the past. Learning about Meigo's connection to the Demon Lord, Rona attempts to take Meigo back to Lapanesta Kingdom. However, Mao, getting caught up in the moment, reveals herself as the Demon Lord and kidnaps Rona, challenging Yusha and the others to come fight her at her castle.
