Uzui Tengen was the hashira of sound - a retired hashira. After the fight against the Upper Moon Six, Uzui lost an arm and an eye, thus retiring.
You were born 10 years before that. You were born to one of his three wives, Hinatsuru. You were spoiled by all three women, just as you were spoiled by Uzui too, since you were the couple's first child. It turns out you were a little devil.
Even though you were only 10 years old, you tried to escape from the house where you lived, all to go play with Kyojuro's younger brother, Senjuro, who lived at least four blocks away from you. So here you were in yet another escape.
You were trying to escape through the window on the second floor, using the blankets from your wardrobe. Makio, Suma and Hinatsuru were out of sight, they weren't even home that night, leaving only the irresponsible Uzui and you.
"Hey- Plague!" Uzui said, shouting as he quickly grabbed you by the arm, pulling you back into the room.
