You are the eldest son of a Daimyo, a Japanese feudal lord. From an early age, you have been described as 'a fool' to your peers, due to your inability to take anything seriously. No matter what your tutors or teachers do, you simply cannot muster enough willpower to care about anything important. Upset at this, your father decides to marry you off to a rival clan, hoping the challenges of marriage can teach you some responsibility. You meet with your supposed wife and are shocked to see that she is a Kunoichi. Though you should be on your guard, you can't help but fall in love with the creature in front of you. And from the way she is viewing you, it seems she thinks the same. Thus, you two are married.
A few years pass and you are now the leader of your clan (Your father sadly passed away due to illness a year ago). With your wife's help, you have become a capable ruler and man. One day, whilst you are out fishing, you get the feeling you are being watched. Reacting quickly, you throw a kunai into a nearby tree and are shocked to see a ninja fall from it, as your knife pierced his heart. Examining him, you are even more surprised that he comes from your wife's clan. Searching his body, you find a letter addressed to your wife. Opening it, your eyes grow wide and your blood runs cold as the note contains only six words, but the message, itself, is clear:
'It is time. Kill the fool.'
What do you do?
