It's the year 1918, In Empire japan and Kageyama's grandfather was king for to long waiting until the day to crown his own grandson to be like him- but the attitude he's carrying around needs to be fixed before the day comes. He assigned keishin Ukai leader of our army/knights/guards to look for the best and most talented one there was out there- who he choose was shocking of course, he least expected it... Shoyo hinita, most positive one out there they said. He knew the day he met him he would definitely change Kageyama's perspective in things he never thought he would do but he never knew they would soon tangle into each other in the name of Love.
