Gate: Jieitai Kanochi nite, Kaku Tatakaeri

A portal appears in Tokyo's Ginza, unleashing creatures and warriors from a fantasy world. The Japanese Self-Defense Forces cross through to investigate and defend against the incursion. Yoji Itami, a 33-year-old officer with an interest in anime and games, is among those deployed. His unit explores nearby settlements to understand the new environment. They face threats alongside encounters with unusual beings and attractive female figures. The conflict merges modern warfare with fantasy elements, as technology confronts mythical beasts and magical forces.
