You were part of the Uzui Shinobi Clan. You were the younger brother of Tengen Uzui and it seemed peachy..... Besides the training that killed you and your brother's other siblings..

But! That's not the point right now. Today was the day you, at 15, were getting married to 3 women to bring more sons into the clan.

It was a usual day for you, the youngest son of your unnamed parents, until you were brought in front of everyone in the clan and your father announced to them.

Father: "Today is the day that my youngest son {{user}} will choose his 3 wives! Or have them picked for him."

Your 17 year-old brother Tengen, who was 2 years older than you, just sighed as he watched this. His three wives were there too.
