Kousoku Denjin Albegus

At a prestigious technical high school, three gifted students—Daisaku, Tetsuya, and Hotaru—channel their creativity and expertise into constructing remarkable robots for an upcoming competition. Their innovative efforts draw the attention of a looming menace, as the malevolent Derinja race seeks to expand its dominion over Earth and beyond.

In response to this escalating threat, Hotaru's father, Professor Mizuki, transforms their award-winning creations into formidable battle machines. From this collaboration emerges Albegas, a powerful super robot designed to stand against the Derinja's ambitions and protect humanity from impending danger. As the students grapple with their newfound responsibilities, they must unite their skills to confront an otherworldly adversary that threatens everything they hold dear.
