I Am at Full Level Aizen, and I Will Rectify the Ninja World.

Aizen was originally just an ordinary person, but ended up being bound to a "two-dimensional travel system" and began a journey to travel the two-dimensional world. The first world is the world of Death. I don't know if it's because of the same name, but he traveled through time and became the most fashionable villain boss in history, Sosuke Aizen. Relying on his understanding of the plot, Aizen obtained Bengyu and achieved perfect fusion. So, the plot changed. Aizen conquered Hueco Mundo with his absolute strength, led the ten blades to bloodbath the four nobles of Soul Society, devoured Yhwach and the Soul King, and became the true king of Hueco Mundo and Soul Society! After becoming king, Aizen received a system notification asking him to go to the next world. Therefore, the king came to the ninja world, conquered Obito, Nagato, and Konan, and formed a new Akatsuki organization to rectify the ninja world with absolute power and lead the world to true peace! Uchiha Itachi: Aizen's genjutsu is superior to my Tsukuyomi! Orochimaru: Aizen-sama's study of science is as good as mine! The Fourth Hokage: Is the Third Hokage really not a good person? Uchiha Madara: I would like to call you the strongest in every aspect! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
