In Episode 6 of Bakuon!!, the Bike Club girls play some sort of strange game to decide who's going to organize the race they're holding for the school festival.
Hane: We're deciding by the popular vote system that Onsa-chan came up with. We each write a character on the palms of our hands, and whoever has the most wins.
Raimu and Hijiri both write 金 (gold) on their hands, which somehow means that Hijiri wins and that her idea has to involve "gold" somehow, which leads her to create a betting pool for the winner of the race.
Hijiri: I win with the most, which means...I'll be in charge of this matter.
Onsa: But how do you make the race more exciting with gold?
How is this game supposed to work? According to Hane, "whoever has the most wins". The most what? It looks like "the most people writing the same character". But then why does Hijiri win, and not Raimu, who wrote the same character? (Aside from the reason that it's hard to organize a race when you can only communicate by writing on a notebook and no one officially recognizes your existence.)
Also, if you're allowed to pick any character, the odds of any of the 50,000 kanji in the Dai Kan-wa Jiten, or even any of the 2,136 Jouyou kanji, getting a majority among five people are quite low. Initially I thought the characters were limited to days of the week, but Rin picked 銀 (silver), which isn't a day of the week.
Since Hane mentions that Onsa invented this game, I assume it isn't a real game, but maybe it's based on something, or was explained more fully in the manga.
