Paramecia · current: (masked CP9 agent — inferred Blueno , unnamed on-page @0343) · named on-page Ch. 343
Profile
Named on-page in Ch. 343 (p. 11): “It’s the power of the Door-Door Fruit. However thick the wall, wherever I touch it becomes a door… as long as there’s a wall, I can get in and out of anything. ” A Paramecia that lets the user create a door in any surface (walls, ceilings, even the air) that swings open to the other side. This is the mechanism behind CP9 ’s “ghost in the walls” intrusions into Galley-La Company Headquarters — the agents vanish from a surrounded courtyard (p. 3) and reappear inside sealed rooms, and the user shoots Iceberg through a freshly made door (pp. 11–12).

User
Blueno Ch. 345 . The bear/bull-masked CP9 agent who used the Door-Door Fruit @0343–0344 unmasks as Blueno (the Water Seven bartender, “the rope guy”). current_user/all_users set to Blueno; Characters/Blueno.devil_fruit set this chapter.
Ch. 388 — Air Door used to retreat-and-regroup, then overrun by Gear Second
Blueno opens an Air Door to break contact and reset against the Gear-Second Luffy (pp. 8-9), but the door-mobility is no longer enough to evade the boosted speed; he switches to Iron Body and is defeated by Jet Bazooka. Last Doa-Doa deployment of the Luffy-vs-Blueno bout. Cross-link Blueno , Luffy , Enies Lobby .
Ch. 385 — fullest combat showcase: floor-doors, a trap-door field, and a free-standing Revolving Door
On the Courthouse Roof (pp. 8-13), Blueno gives the Door-Door Fruit its fullest combat showcase yet against Luffy : he opens a door in the floor , deploys a field of small trap-doors that swallow Luffy’s limbs, and conjures a Revolving Door that spins Luffy until he is dizzy (“Which way is forward?!” / “It’s this way.” / “I’m getting dizzy!!”). Confirms the fruit can make doors of any surface — including a free-standing rotating door in open space — wielded here as crowd-control / mobility against a rubber opponent. Cross-link Blueno , Luffy , Six Powers (Rokushiki) , CP9 , Enies Lobby .
Ch. 382 — the Air Door used MID-AIR to ferry the escape party across an impassable gap
Blueno opens an Air Door in mid-air (a door in empty air, not on a surface) at the entrance to the World Government, letting himself and the escape party — Spandam , Lucci , and the captives Robin + Franky — cross an impassable gap and vanish , leaving Luffy stranded at the last building (pp. 18-19). The first on-page mid-air / free-standing application of the air-door power (the @0374 atmospheric Air Door doored into a sealed carriage). Establishes the mechanic that frames the upcoming Luffy-vs-Blueno confrontation at the World Government’s threshold. Cross-link Blueno , Spandam , Rob Lucci , Nico Robin , Luffy , CP9 , Enies Lobby , Blueno Air Door Through The Atmosphere Doa Doa Application .
Ch. 374 — the “Air Door”: doored transit through the open atmosphere
New application: Blueno opens an “Air Door ” in the wall of the atmosphere itself (not a solid surface), passing instantly from the Sea Train roof into a sealed carriage and disappearing with Robin (p. 15) — “He just made a door in the wall of the atmosphere… using his Devil Fruit power… the Air Door.” Confirms the fruit can door the air, not just objects — expanding the established wall-to-door power beyond physical surfaces. Cross-link Blueno , Nico Robin , Sea Train , CP9 , Blueno Air Door Through The Atmosphere Doa Doa Application .
Ch. 345 — the Door-Door user unmasks as Blueno
The bull-horn-masked agent Luffy knows as “the rope guy”/“the guy from the bar” unmasks among the four CP9 operatives and is named “Blueno!! ” (p. 17), confirming the previously-inferred identity of the @0343 Door-Door wielder.
Ch. 343 p. 11 — Door-Door Fruit named
First and only on-page description of the fruit so far. The bear-masked CP9 agent demonstrates wall-to-door transit and uses it to breach Iceberg’s bedroom and shoot his leg.
