دوا دوا نومي

Opening doors through anything the owner touches is what this Paramecia power provides, marking the eater a Door Human, with its effects first glimpsed in Chapter 326 and Episode 231. The name simply lifts the Japanese pronunciation of the word door, and English releases from VIZ and Funimation retitle it the Door-Door Fruit. Blueno, an assassin of Cipher Pol Number Nine, is the one who swallowed it.

Conjuring a functioning door on nearly any solid is the headline trick, granting the user and their companions passage regardless of how thick or strong the barrier stands. A door may sprout from any body part, a single palm up to the entire frame, and it borrows the rough outline of whatever limb produced it, remaining a usable opening until it closes. Blueno turns this to combat by planting small doors beneath a foe's feet or across their body to pin them, even spinning an enemy's face into a dizzying revolving door. The signature use is the Air Door, an opening cut into the atmosphere that leads into a hidden pocket dimension tucked inside the air itself. That space suits escape, stealth, and covering vast distances unseen, and it shelters him through large-scale assaults, though while hidden within it he cannot touch the outside world until he steps back out. A central drawback is that every door reseals itself after a set span, whether or not he wills it, because in his words a door that opens must eventually shut. The fruit also ranks among the few Paramecia powers nearly unable to wound directly, so its purpose is to bewilder, restrain, and set up later attacks. A non-canon note adds that heavy Air Door use drains stamina fast and that the doors scale to the wielder's own size. Its named techniques run Door Door, the basic doorway with his body as the frame; Air Door, the atmospheric passage into the concealed space; and Kaiten Door, which spins a target's face like a turnstile. The standard Devil Fruit weaknesses still apply.

The ability belongs to Blueno, a bartender who doubles as an agent of Cipher Pol Number Nine. Since he is a large man, the doorways he forms come out roomy enough for normal-sized people to walk through comfortably. He leans on the power chiefly for getting around, breaking into targets, guarding himself and his fellow agents, and escaping the collapse of Enies Lobby, favoring trickery over head-on strikes. Oda once quipped that had Sanji held this power instead, every woman would dread being spied on while bathing.
