I was thinking the same as you but someone pointed me out, what if the actual function of this gen is to bridge the segregation that is by design on the company, lets suppose that they are a actual mixed gen that is outside of the scope of the other branches, they are not JP7, EN,ID or Stars, this mixed gen could on paper collab with anyone because just by being mixed they dont get the idol debuff (because mixed gen dols are incredibly rare) , boys and girls could collab and work with impunity with both branches without any debuff and people would HOPEFULLY not bitch as much because suppose a liver and a stars are on the same team people will bitch less because a DEV_IS is with them
Im obviously being to much optimistic about it, Yagoo pulling a Xsoleil / Iluna this late in the game sounds stupid, i have the belief that IF its a mixed gen is probably because a suit bitched that males are not performing but refuse to dismantle the system that keep them like second class citizens so this was the best compromise they could get
