== In Touhou Canon ==
Despite everything, it's still you.
While you've never existed in Touhou per say, and those who do claim to be involved are often the subject of self-insert doujin/fanfiction and thus get mocked to high hell, the closest you've ever gotten to being in anything remotely related Touhou is the fact that you're apparently playing as yourself in the side gacha game Touhou LostWord. Just with the added-on notice that your player character is always female.
Your ability is presumably some combination of foresight or potent knowledge, and apparent divine favoritism given that half of Touhou author avatar fanfiction relates to the writer being gapped in by Yukari. Optionally, if you wish to avoid a less comical explanation, your ability may actually be related to the unconscious mind or simply enhanced oculars due to Koishi's canonical ability nullifying the core concept of the FTK games. More skilled players can tack on extreme adaptability in times of crisis & the gathering and usage of tactical knowledge. 
=== Presumed Abilities ===
You're best described as an eclectic (wo)man and a jack of all trades. According to your actions in FTK2, you:
* Have exceptional perception & pattern recognition. Your ability to find Koishi clones, who are offshoots of the character who's specific gimmick is not being discoverable, implies that you either have no time for her bullshit or are a living antithesis to her existence.
* Are extremely durable by tanking extremely high falls from elevators. At most your legs must ache or your feet feel burning for a bit, but it doesn't hold you down one bit. Unfortunately, you're not durable enough when you face the wrath of danmaku, so you could simply be immune to gravity.
* Are incapable of being kept down by death due to the respawn system.
* Have high agility, as you can sprint forever.
* Can parry things, by slamming your entire body against something or just kicking whatever is threatening you at the present moment. You can also parry fucking tanks if the situation calls for it.
* Can seemingly dash forward, by pressing LeftCtrl (KoishBox) or LeftAlt (FTK2 proper).Blame Discrud for this shit.
* Are a real human being, and a real hero.
== In FTK Canon ==
The backstory of the Finder varies between games, and even then there is little to be deduced or inferred. The most one can do is use their own made-up backstories as the reasoning.
=== Related to FTK1 ===
FTK1 implies the Finder is running away from a crisis on the surface, given their decision to avoid returning to it and the apocalyptic ambience that is playing in the intro room. Regardless, the player is discovered by, and brought on as a temp-shrine-maiden for Yukari, who's noted Reimu's disappearance and is not very fond of being bored by lack of stimuli.
Although the player can choose to play their character the way they want to, FTK1 appears to depict the Finder with an abrasive and rude personality. 
* They seem to hold an extreme dislike of journalism or even the mere concept of news reporting, as it shows in dialogue with Aya Shameimaru (i.e sounding annoyed with her in Cinnamon Acre and the player responding very snarkily to her upon first meeting her in Koishokyo), 
* The Finder has a tendency to respond with sarcasm to certain characters, much to either their annoyance or dissatisfaction (i.e. recommending Mokou just burn down Eientei and get her shitshow with Kaguya over with).
* Other times, the Finder appears to be somewhat stubborn, or at least that's what Murasa seems to think if you pick certain dialogue options.
An off-hand comment the player can make to a Koisherminal in FTK1 implies the Finder hails from a country that primarily utilizes the metric system, i.e. anywhere not the United States of America, Myanmar or Liberia."I don't speak Imperial."
=== Related to FTK2 ===
While there is no intro room in FTK2 besides the Void Palace, the Finder is still brought aboard by Yukari as a wageslave-without-the-wage-part (so just 'slave') and appears to be the Marisa replacement, given upcoming lore will imply that Sumireko Usami is the new Hakurei shrine maiden in Reimu's stead.
Prior to V.A12b, the Finder was portrayed as a mute protagonist due to lack of dialogue options; however, the update expanded their ability to talk. The Finder seems to have a "fish out of water" personality that occasionally veers into sarcasm, suggesting that they have a lack of familiarity with Gensokyo; though they are not above pointing out the obvious, such as a KAF Worker's bucket lacking water (contrasting their self-declared goal of being a prideful janitor) or telling Byakuren that Murasa appears peeved about something. 
If a reply to a KAF worker inquiring about their day is to be taken at face value, then the Finder may be either prone to self deprecation as a form of humor, or they are simply depressed (depending on how one interprets the claim that they are 'unfathomably miserable'.)
The Finder seems to be an in-universe consumer of anime and other Japanese media, as they recognize the name Rei Ayanami from one of the KAF workers (leading to the worker replying that they'd 'get along' with Yukari) and seem to be aware of Artoria Pendragon's regal status. This humorously implies both Neon Genesis Evangelion and Fate are canon to FTK2, both as media and as likely things that exist within the universe.
== Names ==
The player is called a myriad of names in both games, usually due to the lack of an actual description for them.
* The Human and/or the Interloper: Referred to as such by Koina Matara
* Priest: via Koishi Senri
* Interloper from Above: by Minoshi Prime
* Child of Yukari: by Koishyphus Prime
* Koishi Finder: by Judashi Prime
* Hunchback, Cheapskate, and Walnut: all by Koishee Mizuhashi
* Machine: Several times by Archangel Koishabriel
* Hunter: Potentially through the description of Koizhi von Parseval
* Finder: by Apostate Koishabriel and Judashi Prime
== Jane Doe ==
On September 19, 2024, Marecrisium revealed a character sheet for "Jane Doe", also known as "Jane Koishifinder"; she is a black-haired woman dressed in a stolen Expedition uniform resembling a hazmat suit, who also carries a large brown sack intended for stowing Koishis. Mare has stated that Jane Doe is not canon to FTK2 and exists currently as the role of a mascot/representative for the player character whenever necessary.
=== Relevant Trivia ===
* Her name, "Jane Doe", is a placeholder name intended for when the identity of a woman is unknown/being concealed; it is the natural counterpart to John Doe.
* The name "Jane Koishifinder" is a reference to the gaming culture practice of sarcastically nicknaming a character "John [Game]", i.e. "John Doom", "John Darksoul" or "John Halo" (the latter of which is more probable).
* She is stated to have an odor comparable to surstromming, a Swedish meal consisting of fermented herring which is notorious for it's extremely pungent stench, to a point where the advice given to safely open surstromming is to open the can outside whilst immersing it in a bucket of water. It is unclear whether or not Jane intentionally foregoes self-hygiene, or it is something brought on by her circumstances (running around grabbing Koishis for a hag that could really care less about your health probably would lead to some problems).
== Trivia ==
* If you play FTK2 while wearing a cosplay of anyone that appears in the Touhou games, you inherently write new lore for Touhou. To maintain Touhou's tradition of an unanimously female cast while playing FTK2, use only feminine avatars.
* You and over nine thousand other agents combined (as of September 2, 2024) have visited Gensokyo at some point to do pro bono miko work for Yukari. Technically, given the 6-8 server size used in FTK2, playing with friends essentially creates a new expedition into Gensokyo. Don't fuck it up this time!
* If the Diamond in the Rough web-series (which satirizes and deconstructs self-insert fanfiction related to Touhou) is to be treated as canon, then you are actually called a 'gappy sue' or a 'gappie'.
** There is currently no implication in either game that you were gapped into Gensokyo, since your entrance into both the Seminar Caves and the Void Palace is through leftover elevator tech. Hell, you may be actually a boundary manipulator yourself if the return-to-KAF teleport system in FTK2 or the way to reach the Koishokyo shortcut in FTK1 is anything to go by.
*Given that players collect Koishis by stepping on them, and players Parry by slamming into Threats at full force, it can be presumed the Finder has never skipped leg day.
*You matter.
