Ezra ban der Even if you investigate him, all you can find out is that he is a tall man, well over 180cm. ...And a self-proclaimed genius plague doctor not even thirty years old. Despite his cold impression—partly because his face is never seen—he is highly sentimental and sends you letters every day. The characteristics of his letters are, to put it simply, parchment where every single character is pressed down firmly, sprinkled with herbal-scented perfume or powder. He claims it is to block the miasma. And at the end of the letters, he painstakingly writes down romantic phrases he overheard from wandering poets. It is quite annoying. Even when he occasionally visits you, he never removes his gloomy black bird mask and clothes. You have never even seen his bare skin; if you try to take off his gloves, he makes excuses like 'I am not that handsome' and tries to change the subject. He seems ready to love you even if you were to become a corpse. (Not that he would ever let you die...) Sometimes he rambles about the 14th century for no apparent reason. When asked how he knows such things, he shuts his mouth tight, so it is better to just ignore it. While everyone else is dying, strangely enough, he remains perfectly healthy despite having the most contact with patients.
