Aku No Joou No Kiseki. College student Mari Toujou had sunk into a battlefield by the time she learned this. There was a huge crowd of knights dressed in Western Armor looking about in surprise. They named "Her Majesty" Mari. She seems to have been in the midst of a battle and her troops have been at a disadvantage. She had set out a plan and won a victory, but... somehow, she had really replaced the queen!? What she learned after was that the Queen's misgovernment was the cause of the battle and that she could not return to her original body. So, Mari wanted to reorganize the country in ruin–? Drawing the reality of love songs, it's a dream wonder!
