One futanari girl is dispatched to the battlefield of extremely cold. The name is Ryo Ohba, and the class is a reserve.
She was assigned to a front-line unit with the enemy country “the Grand Duchy”.
But the unit is not tense.
And immediately after her arrival ceremony, the unit is attacked.

It will greatly change the fate of the feathers.
An overwhelming number of enemy battalions. And the siege of a powerful enemy unit called the madness worst.

Ohana scooped them up and started “a withdrawal battle for victory”.
With a little hope changing the fate surrounding you.
