Where can I watch Royal Space Force - The Wings of Honneamise in United States?

On a future Earth, war between the Kingdom of Honneamise and its rival, The Republic, is inevitable. As evolving technology creates new ways to wage war, a small group seeks to propel mankind into space in their world’s first spaceflight program. For astronaut candidate Shirotsugh Lhadatt, it’s a personal odyssey as he grows from an aimless young man into a leader willing to put everything on the line in order to move the human race forward and away from the brink of Armageddon.
