The assassin called Russia

RusAme
Russia is an assassin on the wrong side of the kingdom who took up a year-long job to be the bodyguard of America, next-in-line for the throne. Now, this would be very nice if Japan notified him he will be going to school to protect the prince.
He didn't, but here they are regardless.
Watch as the prince and his body guard make their way through the year, where secrets will be uncovered, shits will hit the fan, and maybe, just maybe, romance.
Fat chance, amirite?
