''[[http://www.fanfiction.net/s/5077152/1/Though_A_Bird_Cant_Fly_Doesnt_Mean_It_Never_Will Though A Bird Can't Fly, That Doesn't Mean It Never Will]]'' is a ''OnePiece'' AlternateUniverseFic in which Zoro's deceased childhood friend Kuina survived her [[DeathByFallingOver canonical fate]], only to be struck blind instead.

With Zoro's encouragement, Kuina struggles to overcome her impairments and become as good a swordswoman as she ever was. Years later, she finally catches up with Zoro, only to discover he's fallen in with Straw-Hat Luffy and his crew. Kuina, in turn, is driven to join up with the Marines (to be more precise, with Captain Smoker's crew) in order to pursue Zoro and either bring him to his senses... or bring him down. Kuina's pursuit of Zoro ends up taking her on the journey of her life, weaving a tale that crosses paths with the familiar chronicle of the One Piece series in interesting ways.

This fanfic provides examples of:
* ArmorPiercingQuestion: Robin gets a very big one during the G8 Arc.
--> [[spoiler:'''Briggs''']] : Did you know of Crocodile's bomb beforehand?
--> '''Robin''' : I was not involved in the preparations for Crocodile's bomb.
--> [[spoiler: '''Briggs''']] : That was not the question I asked you. My point is: did you, as Crocodile's right-hand woman, know of the existence of that bomb- with which he planned to blow up an entire city full of people- beforehand?
* BlindWeaponmaster: Kuina evolves into one of these quickly.
* BossInMookClothing: An inverted example for the pirates. Kuina is a lowly marine recruit but she can cut a sea-king in half.
* DisabilitySuperpower: Apparently being blind makes it easier to have super hearing and [[spoiler: develop haki.]]
* DangerouslyGenreSavvy: Nico Robin [[spoiler: defeats Kuina by throwing her down the stairs.]]
* EntertaininglyWrong: Kuina misunderstanding of Luffy's character and how she thinks Zoro, Sanji and Vivi ended up being in the Straw-Hat crew.
* GrievousHarmWithABody: One of the fights has a marine being beaten up with his own broken-off arm. Ouch.
* HopeSpot: [[spoiler:Pell's alive]]! Nope, it's just [[spoiler:his body]].
* ImagineSpot: Kuina has some ''hilariously'' wrong ideas about what Luffy is like.
** This soon turned into even more ridiculous ideas about what Luffy's crew is like. Her gullible imagining of 'Prince' Sanji especially deserves a mention.
* InspectorJavert: Briggs seems to be set up as one towards [[spoiler: Nico Robin]] in the second season.
* LivingEmotionalCrutch: It's obvious that Zoro and Kuina are crutches for each other.
* MajorInjuryUnderreaction: [[spoiler: Briggs response to having his arm torn off is to just say [[GoodThingICanHeal it will grow back]].]]
* [[MySisterIsOffLimits My Childhood Rival Is Off Limits]]: Zoro has this to say in response to Sanji flirting with Kuina.
* OCStandIn: Kuina herself. In canon, she barely appears in a few flashbacks.
* ParodySue: Kitty Raven the Hunter from Chapter 4, who quickly gets her ass handed to her by Kuina.
* PowerIncontinence: Ironically, developing [[spoiler: haki that you can't control]] proved to be an even bigger handicap than blindness.
* RetiredBadass: Kuina's sensei, Ichii.
* RoaringRampageOfRevenge: Played straight, complete with a TragicKeepsake, even.
* ShoutOut:
** Kuina's sword teacher is clearly inspired by (and named for!) the protagonist of {{Zatoichi}}.
** During one of Kuina's fantasies about Luffy, she imagines him as posing dramatically with a notebook while boasting about his ability to [[Manga/DeathNote kill anyone whose true name he knows]].
** During the G8 arc, one "Commander Shepherd" calls Briggs a "[[Franchise/MassEffect big stupid jellyfish]]".
* SkilledButNaive: Kuina is extremely skilled with swords, but her ignorance of the world outside her village and interpersonal relationships rivals Zoro's.
* SternChase
* TheOnlyOneAllowedToDefeatYou
* TragicKeepsake: [[spoiler: Pier's gloves and then later, Pell's sword.]]
* UnderestimatingBadassery:
** Thanks to her appearance and marine rank, Kuina gets underestimated by her opponent very often.
** Ironically inverted in season 2, when Kuina tries to stop a fight by who she assumes is a simple thug. She gets a very nasty surprise when she finds out the hard way the person in question is actually [[spoiler: Urouge, one of the Eleven Supernovas.]]
