My update: now have reach ch.30.The latest chapter i read 19.2 in Indonesian language.
Hope the English can catch up too
It looks to me that the Sixth Order (where "most of the female members are gathered" and where MC is "the only male Holy Knight") is just a branch of the "Order of Holy Knights" (where "ratio of women and men is ten to one"; should've been "Orders", probably), so no discrepancy here, i believe.If Ruga is the only male and the gender ratio is 10 women to 1 dude then there are 11 people in the order. On page 13, there 10 women not including Carla or Leon. I cannot be bothered to try to see if the author kept designs consistent in the other wide shots. The ratio is thus at least 12 to 1
