Extra: White Day High
I just wanted to add some extra details with this story to make all of you aware on what's really happening. Now, I will explain the nation or the place that Lucas and the rest of the characters resided at. It was obviously at White Day High.
White Day was the main setting of this story, and it is located inside a neutral yet unnamed nation (also fictional) with a population of almost 50 million people. It was located on the westernmost peninsula of the realm they were in, and was surrounded by water by the ports. In contrast, it has other nine big states apart from White Day, each has their own Academy built for the people living there. The capital of this nation was Aspho, the state Lucas previously resided on, and the monetary unit in this nation was as contemporary as money.
White Day was a state in which the current regime is a monarchy and was ruled by past students from different schools that made history with the tournament they were holding each year. This tournament was a survival game held at the most civilized part of the nation, where participating schools compete for the title of being the strongest Academy in the country. Additionally, the winning school gets a reward that no one knows, yet the tournament changes everytime from its last. It was established since the war of schools, so that the monarchs decided to host a game to give titles for the strongest school.
