Isekai de "Kuro no Iyashi Te" tte Yobareteimasu

One day, 22-year-old Kanzaki Misuzu is suddenly transported into a strange world. Based on the pop-up screens she can access, it seems like she has entered some kind of RPG as a magic user! Luckily, she can use her gaming skills acquired as an otaku to make her way in this new world, but before she knows it, people start calling her the "Black Healing Hand!"
