One Piece.S10E360.Save Me, Hero!! My Enemy Is the Immortal Princess

Usopp is forced to go through a gauntlet of Perona's Horo-Horo powers, including an untouchable body, size manipulation, passing right through him and creating explosive mini-Hollows that slowly rip away at his stamina and body. Temporarily turning into Sniperking to finally dispatch Kumacy, Usopp is forced up against a desperate wall until he finally realizes Perona's sudden change. Usopp uses one of his attacks to destroy a nearby wall, revealing Perona's body lying helplessly in her bedroom.
