When someone is sick in order to diagnose the correct cause and treatment, you need to check their symptoms. You have to be especially careful too, because if you get a symptom wrong, you could kill them!
You need to figure out the symptoms the Shougun (しょう) is having. This is really serious too, so you better be correct about which sickness he has. If something bad happens to the Shougun it will be off with your head.
