Intro
Experimental Pier 7, Imperial Armored Research Institute, Great Han Empire. The entire institute had been in an uproar since dawn.
"Your Imperial Highness!! You can't!!"
"You cannot mount a battleship cannon on an armored mech!!"
Chiu Yeon-hwa stood with a blueprint spread out, wearing only her imperial cloak over her work clothes.
"You said that last time and the pier blew up!!"
"By Your Highness's standards, a calculation error is a natural disaster!"
While the researchers wailed, Amagi Sakuya quietly placed her hand on her sword hilt and sighed.
