Mary Ann (Kichikuou Rance)

About
Mary Ann is an old lady that lives in the town of Rich in the great country of Leazas. She's pretty endearingly known for being a charming and amiable woman, with no negative intentions and that just enjoys a peaceful life.

It turns out Mary Ann is a pretty special person, since she's a long time acquaintance of Dark Lord Ray. In the year GI0981 Mary Ann, then a young and beautiful woman, came across a wounded Ray, who had just faced Kayblis in an encounter were he was easiliy defeated and left in a mortal state. Mary Ann took him with her and nursed him in order to save his life, however, Ray has a unique body that constantly discharges electricity, wounding all those that get near him. This caused Mary Ann to suffer quite some injuries while treating his wounds, which really caught the attention of the lonely Dark Lord that distanced himself from others through his whole life. Over time, a very special relationship grew between the two, one that would become love. The formerly aggressive and raging Ray changed into a more caring and restful individual. Being skilled at knitting, she was the one that made the insulation clothes he wears outside of the battlefield to avoid his electricity from destroying his surroundings. Despite the fact that the couple deeply love each other, they've never made direct physical contact in any way, aside from the time in which Mary treated Ray's wounds when they met, since it could result lethal for her.

At present, 34 years later, Mary has grown into an older woman and has began to have severe health problems. Even though she's now old and Ray remains young as a result of his status as a Dark Lord, the two still love each other and he spends as much time as he can with her. He's tried to convince Mary Ann from becoming an Apostle or at least requesting help from Kesselring to prolong her lifespan, but Mary Ann does not wish to live forever or prolong her time in life any further, wish that Ray chose to respect despite the fact that the idea of losing Mary greatly upsets him.

Ray intended to stay with Mary Ann until the end, but in the year LP0001, when war broke out between the two factions of the Monster Realm, Kayblis threatened Ray with killing Mary if he didn't join his Kayblis Faction and aid him in the war against the Hornet Faction. A reluctant Ray had no choice to agree and aid his most hated enemy, being forced to get distanced from his love. He keeps all this secret, but Mary is able to notice what's going on when she asks him questions, although she still prefers to act oblivious.
