The Protagonist Is Dead and the Villain Is in Power

What would a world without a protagonist be like? "Ace, use fire fist on him!" Ace finally lost all reason after hearing these words. "My godfather! I bow to you!" Momonosuke, who traveled from twenty years ago, finally admitted defeat and knelt down in front of the black charcoal snake. "The age of ninja is over. Gather the kunoichi in the village. In order to obtain information, they need to learn new 'ninjutsu'." The fifth generation Hokage Shimura Danzo ordered. "Weak people are not allowed to enter the guild!" Laxus, the fourth generation guild leader of Fairy Tail, successfully usurped the throne. "Successfully recaptured the Ancestor Titan! Now start returning!" Reiner shouted excitedly. "Starting today, the Wuhun Empire is officially established!" Bibi Dong declared to the entire Douluo Continent. "Zhang Zhiwei is dead! The new era of aliens has arrived! Hahaha!" The whole world was boiling. Voldemort and Orochimaru jointly explored the way to immortality, Crocodile and Gaara joined forces to become the twin emperors of the desert, and Tsuji Muzan became the ultimate creature that is not afraid of the sun. Without Saitama, can One Punch World survive the crisis? Without Xiao Yan, where would the Xiao family go? Without travelers, who would do those tasks in Teyvat? Justice disappears, heroes emerge, the protagonist is dead, and the villain takes over!
