To say what's in a samurai's heart you start a magazine. You go around writing about and interviewing all the samurai so you can share what they say to everyone who wants to read!
Unfortunately, your magazine helps the sheep (し) samurai find other samurai... and kill them. None of the samurai want to share their feelings with your magazine anymore, oh no!
