Chiaki is Fumika's coworker, though unlike Fumika, Chiaki has already died. Chiaki died due to a car accident and thus retains the appearance of how she looked before she died, which happens to be very similar to Fumika, though Chiaki does not age. Believed to have been eighteen when she died, she is "over twenty-one-years-old" as she says, however she looks roughly as old as Fumika is. She is assigned a different city in Japan than Fumika, and the two rarely ever meet on Earth, but do see each other more often when in Shigo. Chiaki has a bright personality and likes to express her emotions outwardly, whether they be related to frustration, or happiness. As observed by Fumika, Chiaki usually is not as diligent about her job as Fumika is, and if a delivery is too much of a pain, she will generally drop it, marking the letter with an invalid addressee.<br /><br />
