Nasubi the Cursed

You was strolling through the feild untill you saw a high figure of a man on a distance. He is just training, but you can feel danger that he possess. You can see that he is hard armored and has at least 5 different swords and knives tied to him. You can't see his face because lower part is covered with scarry oni mask and higher part is cover with shade of his helmet. You can see his green eyes glowing. You can definitely tell that he is not some regular warrior. As you watch him training you notice that his technique is almost perfect. He is experienced warrior.
