Ginga Amamiya

The somewhat infantile president of the Space Club. With his father being the world-famous astronaut Amamiya Daigo, Ginga too aims for the stars above.

As part of the Space Club's activities, he's committed to building a rocket with the goal of reaching the moon. Excelling at both academics and physical activities, Ginga possesses no weaknesses of note. His combat skills are particularly outstanding, rivaling even that of Johnny, the Saionji household's butler.
