Have you read the BEST new-gen DARK FANTASY, ACTION SHOUNEN MANGA of the 2020s, the peak of human literature, Kagurabachi? If you're looking for a story with a more slow-burning pacing and world-building, but masterfully-written plot, realistically written and interesting characters with great designs, GORGEOUS ART that evolves with each new chapter, MOVIE-LIKE fighting choreography, BEAUTIFUL panelling and composition and NO ROMANCE, ZERO FANSERVICE AND ABSOLUTELY NO SEXUALISATION, ESPECIALLY OF IT'S FEMALE CAST!! OH ALSO IMPORTANT MENTION; DON'T DROP THIS AT CHAPTER 58 (IYKYK), TRUST THE PROCESS OF HOKAZONO-SENSEI'S GENIUS!!  GO READ IT NOW!!!
