Voice
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.
せい
こえ
None
You decide to join the samurai’s protest for more voice but immediately notice… they’re all 子, eh (こえ)?!
