Kiyoshiro Yumemizu. If anyone asked what his name he sure will say forget. If people who know him say hi, he'll said "when we meet?" Even he forgot how to eat, when you meet a very difficult case he will directly give his name card, "The Greatest Detective Kiyoshiro Yumemizu" to people in need. Ai, Mai, and Mii Iwasaki are triplets neighbors who always remind Kiyoshiro everyday. Note: Won the Kodansha Manga Award for Children's Manga in 2009.
