Reborn in Naruto, but I Have No Chakra

I was reborn in the Naruto world. But I became an unofficial member of the Uchiha Clan. Since my innate constitution won't let me refine chakra, all I can do is run a small business, laze around with the old folks, play shogi, open an izakaya, and brew some good drinks. Thirty years east of the river, thirty years west. Don't look down on me (not really). You ignore me today, and tomorrow I'll be out of your league (not really). What's wrong with being a layabout? I can raise a cat and run a shop, and I don't have to go to the battlefield and fight for my life. I love being a layabout. Until she arrived.
