Ryuujin Kakusei

Inside the popular VRMMO where you can fight massive dragons, [Angolmois Field], Sudou Masaki, the world’s best player, defeated the dragon emperor. At the same time the game suddenly ends its service abruptly. But one day, the dragon emperor and its minions appear in the real world. The humans are put to the trial. Masaki knows that the scenario is just like the game [Angolmois Field] itself. If he were to obtain the [Sword Scale], he can manipulate the power of the dragons itself, and be awakened as a [Dragonoid].
