Attack on Titan: the Eldest Son of the Yeager Family

Roy, who traveled to Parade Island, became Allen's biological brother. What about the daily variety comics you promised? There is probably no chance of such a younger brother with many strange titles on the stall. Fortunately, the system woke up. In order to live an ideal life in this so-called cruel world, Roy had no choice but to try hard. The royal family seizes power in one fell swoop, discloses the truth, develops science and technology, and integrates with the world to launch the earth's revolution... Everything must start with wrapping your love brain in a scarf. Mikasa: As long as you are here, I can do anything. Historia: I want to be a wife! I don't want to be a queen! Allen: I will keep moving forward, die while moving forward, and keep moving forward after death, until I help my brother clear all obstacles. This novel and its characters are purely fictitious.
