Kankin Onna Kishi ~Isekai Tensei Shitara Orc ni Machigawareta Otoko~

The protagonist is transported to another world, but because he resembles an orc, he is persecuted and forced to live in a forest on the outskirts of town. One day, a female knight arrives after hearing reports that an orc has appeared in the area. Mistaking the protagonist for the creature she is hunting, she nearly kills him. He is saved by the mysterious power of an old, weathered pot that had been lying in his yard. However, if the knight's companions arrive, he will be killed, so he must somehow win her over before that happens. He has only five days. With the mysterious pot's power at his disposal, he begins training the female knight. ​
