Husk, Shell
A samurai puts his forehead on the table next to his weapon. He is just a husk of his former self. This shell of a samurai has nothing left.
He's just sitting there, he can't even pick up his weapon or raise his head anymore.
かく, こく, ばい
から, がら
None
The only way to bring a husk of a samurai back to life is to have a cock (かく) crow right in his ear.
"Co co co co cooooock!" the cock screams, shocking the samurai back into his lifeless shell. You did it!
