This study investigated the boundary of agent's imaginary body. Many anthropomorphic agents are used for human agent interaction. These agents have various body form and appearance. These tolerate attitude for diversity of appearances suggests that a user can recognize wide-ranging imaginary body compared with human native appearance. So, how wide can we extend each body of an agent? According to previous studies, we construct one hypothesis that this difference is depends of order of each parts. If each body parts of an agent is placed in order from top to bottom. A user can accept the body of an agent as one concrete body. According to this hypothesis, we construct human-like eyes and a mouth. And we setup two situation that and compared them. As a result, we can find out a significant difference between two groups.
