I have a very strong suspicious that MC will purify ML. In previous chapter that isekai "saint" wanted to replace/posses MC because in the novel she read when this happens to ML only a saint/powerful mage can purify ML. But since we know MC has "main character" mystery magic skills and was secretly raised by 3 superpowerful fairy godmother (her "maids"), the MC should easily be able to purify ML
