Sei Juushi Bismarck

Humanity has expanded beyond Earth, establishing colonies across the inner and outer planets of the Solar System. To manage this vast territory and ensure security, the Earth Federation Government was formed. Tensions arose as settlers grew dissatisfied with the government's control, leading to a fragile peace between Earth and the colonies. This uneasy balance was shattered by an unprovoked invasion from the Deathcula, a non-human species that launched attacks on the colonies, killing many. The EFG found itself outmatched due to the Deathcula's advanced technology. In response, Dr. Charles Louvre designed the Bismarck, a transformable starship. To operate it, a team of four specialists was assembled with the mission of defending the outer colonies from further attacks by the Deathcula.
