Reliving the life in a world of guns

The legendary Finnish Soldier from the winter war, named as Simo Häyhä but recognized as "The White Death" unfortunately, he died in 2002, yet his life will not end there. He will be given a different life, to enjoy being the honorable soldier he once was.
Now brought back to a new world, a world of literally guns embodied by girls, brought to a new war to be the white death in that one. Simo Häyhä will turn this from Girl's Frontline to Death's Frontline, also BEPIS!!!
(I do not own Girl's Frontline)
