Well if it was such a dictatorship he might have had one (or more) concubine(s). He pointed at a girl, or had a harem or something, it's more than enough for one to get pregnant. Also we don't know how old Yagura was when became the Mizukage, based on several examples we've seen on Naruto, he could've been 14 or something and died in his late 20s. He might have had a 'sweetheart' before he became a Mizukage, before Obito's control, she might have had a child round the same time Obito took over, it would work out fine chronologically (which doesn't always happen with canon-Kishimoto material).

There are so many feasible possibilities for Yagura to have a kid
