Horo Horo no Mi

This Paramecia lets its user summon obedient ghosts, branding them a Ghost Human. The fruit was first eaten long ago by Gill Bastar, and after reincarnating it passed to Perona, the one who made its powers famous. Its pale-yellow body splits below a green T-shaped stem into five upward-curving sections, each marked with a spiral and eye-like dots that make them resemble sheeted phantoms. The name comes from horo, the Japanese pronunciation of hollow.

Whoever eats it can summon translucent, white, big-lipped phantoms called Hollows at any size they please, every one bending to their will. These specters take to the air and, having no physical body, shrug off blows entirely. Plainest of them are the Negative Hollows, and they are the cruelest: pass one through a person and they crumple into brutal self-hatred, at times drifting toward the wish to die. By contrast the smaller Mini Hollows and the bigger Toku Hollows have substance, so they cling to a target and blow up on cue, the blast growing with the phantom's size. The wielder can also thread their awareness through a swarm of Negative Hollows to run an intelligence-collecting Ghost Network, or cast their own soul out as a weightless double that soars, resizes itself, and calls up further ghosts. The main gap is that the despair effect fails on anyone already gloomy, which Usopp demonstrated when his native pessimism turned it back on itself. Tools such as an Impact Dial can soak up the exploding shockwaves, and once the wielder projects their soul away, the body left behind sits helpless, open to harm and unable to fight back.

Perona is the principal user, deploying the fruit for both battle and surveillance across Thriller Bark and weakening enemies so allies could finish them. Her named techniques include Negative Hollow and its multiplied Negative Hollows; Mini Hollow detonated by Ghost Rap; Toku Hollow set off by Kamikaze Rap; and Yutai Ridatsu, her astral projection. Her claimed strongest combo, three Negative Hollows plus a Toku Hollow, was cut short when Bartholomew Kuma flung her away. Little is recorded of the earlier owner, Gill Bastar, except that his summoned ghost bore three prongs atop its head rather than Perona's smooth sheet shape.
