A being actually meant to represent [[Mizuki Hitoshi]]'s little sister within the context of his strip "Hang in There, Kogasa-san":/pools/2420.  Depicted as a bright green [[karakasa obake]].  As she lives out in (relatively) rural Kōchi on Japan's Shikoku Island, she's shown a strong desire to take in standard tourist traps, such as  [[Tokyo Disneyland]] and the [[Tokyo Skytree]] (or at least its Sky Town shopping center), when she visits her brother in the big city.
