Invaders of the Rokujouma!? Volume 47

Thanks to Kiriha, Clan, and Ruth's desperate decoy plan, Koutarou and the others discovered the enemy stronghold. With the newly rebuilt Blue Knight battleship serving as their banner, the Imperial Army launches a large-scale offensive to put a quick end to the war. As the curtains rise, Koutarou's personal spaceship, which was seriously damaged during the previous war, is revealed and its appearance is truly extraordinary. At last, behold the strongest battleship that Theia, Clan, and all the citizens have been waiting for!
