Working for Zen, Obi, is a strange (but lighthearted mostly) and unusual character in the story. His first appearance is when he tries to frighten Shirayuki by shooting an arrow to a wall next to her. He tends to hide his face under a mask, which makes many people think of him as a bad guy. He later starts showing to have feelings for Shirayuki, for she is the only person that understands him. Out of all the characters in AnS, he is the only character with unknown motives for following Zen so far which makes him a rather mysterious character.
