Soldiers, especially those on a mission, should not be emotional.
Volunteer turned salary thief, then mistakenly promoted to Colonel and Captain of the battleship, Pasiphael, held a deep memory and experience of this saying. Of the many mottos in the military academy, only this one resonated with him. The others, such as "A soldier who doesn't want to be a marshal is not a good soldier," and "The military is noble and sacred," were returned to his beloved alma mater and the always sighing teachers the moment he stepped out of the military academy's doors.
It was ironic that Pasiphael, who so valued "being unemotional" in his rational approach to military service, was now deeply mired in a frustration he couldn't shake off. The Captain, who typically lamented without any enthusiasm, "When can I finally live the ideal retired life?" was now rarely erupting in anger.
