ばい
う
None
There’s a samurai with (just) his forehead and legs. Everything in between is missing. What happened to everything in between? He was low on money, so he had to sell it all, leaving him with only the top and the bottom.
If you see a samurai trying to sell all their body parts here's what you should say, "Bye (ばい)!" and just get the heck out of there. Actually, if anyone tries to sell you a body part you should probably say bye over and over until you can get away from them.
