It is stated that Kyou was the youngest member of Qin6. Meanwhile, to become Qin6 she need to become General first then Great General. And only after that she could became Qin6. Meanwhile she is wanted to marry Ouki, but have to Conquer 100 cities before that happens. And by the look of it, Kyou is seems fairly young when she died. and the age gap between her and Ouki is not too much i think. probably around 12 - 15 years. So i think that she got promoted to General at age 20, then got promoted to GG at 24, then Q6 at 25, and finally got slain by Houken at 28. What do you guys think about it?
