A crossover fanfic with no romantic pairings. An atypical cosplay story. The degree of physical resemblance is based on Gintama; characters fully possess their skills, but may not necessarily know how to use them.
The dimensional walls of the anime world have collided violently, and important white-haired characters from numerous worlds have mysteriously disappeared. Just as the various world wills are at their wits' end, Gintama's famous white-haired survivor, Gintoki, delivers his classic line: "All silver-haired characters are played by me."
The other world wills suddenly see the light. So, for no apparent reason, Gintoki is asked to take the blame and begins a life as a Yorozuya odd-jobber playing all kinds of other white-haired characters.
Naruto world
Kakashi "Fifty-Fifty" Hatake, huh? Gin was already pretty good at cosplaying him back on the Gintama set.
Naruto: Teacher Kakashi, your eye fell out, dattebayo.
Gintoki: They're colored contacts, colored contacts.
Detective Conan world
Thank the author for having a conscience and not making Gin play Vermouth or Curaçao.
Vermouth: Gin, you've been acting a little strange lately.
Gintoki, holding up a gun with an already-smoked lollipop in his mouth, wears a cold expression. "Are you telling me how to do my job?"
Jujutsu world
This Gojo Satoru is Gin's class enemy. So unfair! Sob, having money is great.
Megumi Fushiguro: Did the Gojo family go bankrupt, or did you finally break your brain by eating too much?
Gintoki picks his nose. "Either way, I'm here to help. The money I spend is all part of the compensation I deserve."
Bungo Stray Dogs world
Shouldn't Gin get to be the protagonist for once? If not the weretiger, then surely some honest guy? Who's this white-haired guy dressed like a circus clown?
Fyodor frowns. "Gogol, did you hear the whole plan just now?"
Gintoki, sleeping with his eyes open: "I got it~ My dear best friend."
