Cross is her boyfriend, silly. That ring fixation is gonna foreshadow the new power of love. Love is the strongest and most twisted curse. Maru won't get the buff, it'll be Yuka.
Gege is fixing his mistakes: he has his girl Yuta, and male Maki as level 1 starter point. Gotta set them up with Maru as new trio. Yuka will get a sinful amount of cursed energy, but her heart is "Hollow" for now. Cross and the Power of Love with fix that and heal her tumor.
