A robot entrusted with the protection and education of Drossel von Fl&uuml;gel, for whom his name is of little importance.

Drossel, an heiress from a long aristocratic line of the House of Flügel, resides in a castle called the Tower of Tempest. She lives there with her large robotic butler Gedächtnis, who has been serving the family for generations. He reveres Drossel’s late father and diligently serves as her caretaker. Drossel also cares for Gedächtnis with whom she has grown up. They pass the time with supposedly intellectually stimulating conversations, only to be interrupted by unexpected, wacky events at times.

He is an actor, voice actor and narrator. He is currently affiliated with Mausu Promotion. He is a Hanshin Tigers fan. His "Kojirou" alias is not to be confused with [Akito Sakuragi](https://anilist.co/staff/125572)'s alias (they have different kanji at the end).

Drossel confesses she has had a “dream” about a human. When she insists that the first step toward achieving peace with him is to find common ground through words, Gedächtnis lectures her about the characteristically human phenomenon of “evolving language.”

On an ordinary planet in the distant future. Humans have long been at war with the mechanical aristocrats called "Hyperion." This is the story of Drossel, a Hyperion and the daughter of the Duke von Flügel, and her butler Gedächtnis in the Tower of Tempest, isolated from the outside world. Their daily tasks revolve around managing problems that occur in their high-rising castle-tower while awaiting the day the stars realign themselves.
