My Iron Rose (Sugawara X Male Reader)

Okay, this is my first ever fanfiction but I do have pretty good idea for this story. This story will have its own plot which I'll explain now, I won't spoil too much of the story in the description.

The world story is placed in is different than ours. Many countries do not exist anymore and others changed drastically. Life in them is still normal. Now most powerful country is newfounded Iron Empire, ruled and founded by the Iron Rose family (Names are stupid Ik but I kind of like them). The current emperor has four sons only the oldest is destined to take the trone. But the other sons do receive important position. While the (B/N) is taking the trone, his younger brother (Y/N) will be placed as the general in command of the special force Iron Rose logically founded by the Royal Family as a force loyal only to them and made with a goal of defending the family and the country. Over the years they have grown to be one of the most powerful armed forces in the world. While their numbers are not enormous every solder is incredibly athletic, high skilled in any tipe of combat, highly intelligent and trained to kill with any type of weapon. They are most skilled in using swords, so skilled they could parry guns. So fast and precise they can deflect bulets and thanks to their speed dodge many of them. Experts in assassination and in open combat alike this incredible force is now in command of 18 (Y/N). Young but experienced he might be the most powerful person ever to wear Iron Rose uniform. After mission in Siberia, Pacific, Arabian Deserts, Mountains of Tibet, Amazons Rainforest and nearly every part of the world, (Y/N) and his elite task force are now dispatched on a mission in Japan to take down mafia who threatened the Empires stability. Will something new happen or will this just be another routine mission, maybe one there will be one faithful experience that will take romantic turn.

Okay that was long but its a backstory of tge world so I hope you enjoy the story!!
