Hikari is a kind, talkative, short, and haggard looking ghost who's searching for a way to bring back her memories, along with her friend, Night, an annoying ghost who loves to tease her. As her journey goes, she met a teacher that caught her attention. Assuming that they have connection with other, she followed him wherever he goes, until she met a snobbish spirit medium named Licht, the guy who has the ability to take a peek in a spirit's memories. -AvidDreamer_
