When our protagonist becomes the game character Jun Karentia, she thinks she has it made. She may be just a lowly support mage, but with her knowledge of the game, she knows she can finagle her way to the good ending following around the main character, Fabian. The problem? This game doesn’t end after one playthrough. Jun is prepared to guide Fabian through the second playthrough to the true ending when… Fabian abandons her. Now the Grand Duke Mayer Knox—captain of the Dark Knights and the secret final boss—is determined to have her join his party. Can Jun turn the final boss into the main character? Why is Mayer Knox so intent on having her in his party? And when will these rumors about being his lover stop?!

There are 7 dimensions controlled by a Universal Government. Each dimension is governed by its own unique universal laws. There are a few things they have in common, there is always 1 the strongest and 1 the smartest. Except for the Universal Government, it’s forbidden to travel between dimensions. Interdimensional gates don’t close on their own and if left open, creatures that dwell in the darkness between the worlds will find their way through. Without warning, one of the dimensions disappeared without a trace. The remaining 6 in panic did all they could to find the reason why. They never found an answer. 12 years after the dimension vanished, a signal started appearing in the empty universe. Perhaps the answer is in that signal.Tsugi No Level
