Voice
You have a samurai with a flag on a stick. On his flag is this symbol, 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
Once you start asking the samurai more specific questions about how he wants more voice he starts playing coy (こえ) with you. He doesn't really know what he wants, he's just here for the sake of protesting.
