Healers

This category is for warriors who are primarily healers, either through gameplay (eg has a lot of innate healing skills) or through story. Klaudia von Auslese fits the first, as she both has innate healing skills and is forced by the customization system to learn healing spells; Kirei Kotomine fits the second, as his magic ability is healing and spiritual surgery in lore despite his propensity for battle; Estellise Sidos Heurassein fits both as she learns healing abilities and is the sole user of them in cutscenes. Yu Narukami does not count, as his healing personas are not required.
