Although short-lived, the fight between Knight and Ice General was put up to decent standards, IMO.
The battlefront as the army advanced from the made-up strait of ice towards the Bright Island was as well dramatized with such raw passion.
We got two accomplishments:
1. Bright Island was retaken by the Human Army in order to open alternative trade route so as the Southern Nations not to have to depend entirely upon the Central Nations, though at the cost of so much Demon and Human lives.
2. The other City far to the South where Yuusha instill fear and superstition in order to force the current Commander to quit and yield his position to his Second-In-Command, a man much more decent and truly concerned for the lives of the human inhabitants that provide supplies to the city. Since desperate measures require drastic solutions, he allowed Demons to intermingle and to coexist with humans in the City, in order for that group to provide economic support as well.
Now to the fun stuff:
We know now where Yuusha got all of his perverted inclinations. The Old Man sure wanted to take a touch on Maou's flesh.
And, Yuusha don't throw away Knight when she so histerically wants to hug you so badly in public before the sight of Maou.
