With this happening this late of the game, if this manga doesn't have harem ending...
As far as heroine progression goes Anna(cos Earnest is アーネスト jp) then Mao are both on the lead with Sophie right behind.
On the girl's end, Luna us actually the only one who is straightforward in aiming for Blade despite having least development currently, since Anna, even tho at the lead is still tsundere at times.
Mao, Yescha and Claire however are fine with being just lovers and not a wife, while Sophie is fine eitherways with her 'as long as Blade is happy' catchphrase.
