Synopsis[]
While walking home from school with her friends, one of Chikitaro's female classmates spots him dancing with the boys from his class and recalls her growing suspicion that he might be an alien, having previously seen him drink ten cartons of milk in one sitting. Determined to confirm her theory, she later follows him closely at school to gather evidence. However, her plan backfires when Chikitaro, imitating Jiji's flirtatious way of speaking to girls, makes a bold remark that leaves her flustered and fleeing in embarrassment.
