One Piece Chapter 1191 was officially released in Shueisha's Weekly Shonen Jump Issue #39 for 2026 on August 23. This chapter was extremely significant for the character of Nerona Imu, who serves the role of the primary antagonist of the entire series. Imu made his presence known in the ongoing Elbaf arc in One Piece Chapter 1179 and has since then been on a roll, beating one main character after another. He has already defeated the likes of Loki and Luffy once, and as the battle continues, Eiichiro Oda is highlighting more of Nerona Imu's abilities, all of which stem from the powerful Devil Fruit Akuma no Mi.
