Minister is a robotic character originating from the same world as Takostu, formally designated "Einaina Sonesone, Carbonara, Pescatore, Holohology 291." As a newer model than Takostu, Minister possesses significantly advanced electronic brain capabilities.

Physically, Minister features a pink head hat functioning as a compartment for deploying various tools, differing from Takostu's mouth-based storage. The character exhibits a narcissistic personality with a flirtatious streak, often directing unsolicited advances toward female characters. Minister frequently makes sarcastic remarks aimed at Takostu, reflecting their competitive dynamic.

Operationally, Minister demonstrates pragmatism, employing any means necessary to achieve objectives without inherent cruelty. The character's alignment shifts to cooperation when influenced by protagonist Kaede Minami. Mirumo nicknames Minister "squid."

Following Takostu's ascension to kingship, Minister assumes the role of minister in the new administration despite initially expressing disgust toward Takostu's leadership. Minister concludes involvement in the primary storyline by participating in the celebratory events for Queen Marine and King Faure's union, offering congratulations alongside other supporting characters.
