You have a samurai with a flag on a stick. On his flag is the symbol 声, the kanji for voice. Why does he have that there? He feels like his shogun isn't giving him and his fellow samurai a voice, so he's brought a flag with the word "voice" written on it to protest.

You decide to join the samurai's protest for more voice but immediately notice… they're all 子, eh (こえ)?!
