To be fair Elmenhilde has already had more development than both Kunou and Yasaka, all she needs now are some erotic moments with Issei, have him grope her as well as a touching romantic moment and she'll be set for a proposal, thats how the others did it

Yasaka had her moments but needs a little more development

Kunou simply needs to mature and grow
