Is Pica dead?

Pica is not stated to be dead in One Piece. Zoro cuts through Pica's Haki and lands a decisive slash that makes Pica scream while the stone giant collapses into falling debris. ch. 778, p. 15 Earlier scenes show Pica commanding massive stone forms and rampaging across Dressrosa without any fatal outcome described. ch. 747, p. 9 Pica's real body is forced out of hiding during the fight but the sources end with the attack landing and panic below rather than a confirmed death. ch. 778, p. 13 "Zoro finally forces Pica's real body out and slashes toward him with 'Sanzen Sekai.'" ch. 778, p. 14 "Pica screams as Zoro's slash lands." ch. 778, p. 15 "Pica's body completely breaks apart causing debris to fall toward the city." ch. 778, p. 15

The manga never states Pica is dead directly.
