And Thus Delta Force Fought Here(A Gate Harem x Operator MR)

Y/N Burnwood is an American Special Forces operative based in Okinawa near the Ginza District. He decided to do some sight seeing, all was peaceful until a portal opened up and a army straight from the medieval comes through and start's causing havoc. Y/N being one of the most elite special forces operatives in the world does what he does best. Which is fuck shit up and kill anything with malicious intent. Y/N's record is one of a kind having quite the combat experience including a massive raid on one of The White Mask terrorist groups compound, the fall of the Santa Blanca Cartel alongside The Ghosts. And more that cannot be disclosed.

Later on after that the Japanese government decide to send the Japanese Self Defense Force or JSDF for short with Y/N alongside them as an alley and sort of war corespondent for the United States. This is where our story begins.
