Urawa is introduced as having the highest score in an exam, and secretly has powers that allow him to see the future, though it is unclear whether he used his powers to cheat. Urawa has feelings for Ami Mizuno, but is too shy to admit it. He becomes embroiled in the Rainbow Crystal arc for being the holder of the Yellow Rainbow Crystal, Bumbo. He is also one of the few good characters to explicitly state that he knows a Senshi's identity, as he often calls Sailor Mercury by her civilian name. It is implied that he knows this from his powers.
