Space Battleship Tiramisu Vol. 4

Set in Space Era 0156, tensions are rising between the Earth Federation and space immigrants. On the brink of war, Earth’s federation of states sends forth a new space battleship: the Tiramisu. Abroad the Tiramisu is ace Subaru Ichinose, a handsome and brilliant pilot who earned top marks. Unable to adjust to life on the ship, he simply shuts himself up in the cockpit of his personal ship, Durandal.
Subaru is unconscious after taking a bullet for his older brother, Isuzu. Meanwhile, something terrible happens with the Subaru copy Subaru B! After waking up as Subaru Beyond, he boards the massive Hades Durandal and tries to attack Subaru, but he’s a bit bad at dealing with people older than him… The epic sci-fi comedy continues in volume 4!
