If Non doesn't feel up to coming back, they should see if Nio Nakatani can do it. She and Iruma already have multiple successful collabs under their belt, after all.
I do admit, that thought did cross my mind when we got that illustration, although it would probably be better to have someone with a style closer to Non's to keep the novel illustrations more or less consistent.
Oh, yes please, that would be sick. Though i heard somewhere, her next work will not be yuri.
Her own manga, sure, but she's already illustrating another yuri novel as well.
