When Will the Zenin Clan Fall?

I was born into a large family so incredibly feudal that it remained so even in the 21st century. Nine out of every ten people raised in a family like this go crazy, and the tenth is well on their way.

I don't think I'm one of the crazy ones. I'm an ordinary person in good mental health.

My dream is to be someone who doesn't want to work hard and doesn't want anyone forcing them to, living an ordinary life of getting up early for breakfast, taking a nap at noon, and going for a walk in the afternoon. But my technique is so powerful that the entire family is doing everything they can to groom me as the next clan head. That leaves me with much less personal time, and everything has to come after the family's plans. I didn't want to become clan head, but my uncles said that if I did, I could do whatever I wanted.

I thought it over. A little effort now in exchange for a lifetime of ease seemed acceptable, so I obediently accepted the family's training.

All my uncles said I was a well-behaved child, much better at reading the room and knowing my place than Naoya. I nodded and accepted their praise.

Later, I became the head of the Zenin family. The very next day, I wiped the entire family off the map.

Wonderful! Now I can finally enjoy a lifetime of ease.
