Akazukin Chacha

Synopsis

Shiine and Riiya are invited by Seravy to a sleepover at their home. Chacha agrees to go to the school dance with Riiya, leaving Shiine heartbroken and jealous. During their bathtime, Shiine freezes Riiya in the tub which causes Riiya to get sick the next day, having to miss out on the school dance. Shiine is delighted because he can now take Chacha to the dance.

Riiya, disobeying Seravy's orders to stay in bed, escapes and heads to school determined to dance with Chacha. However, his colds and fever get the best of him so he is taken to the school clinic where a very creepy, pale-faced nurse tends to him. He tries his best to escape, thought efforts go futile. At the dance, Chacha and Shiine feel guilty and too sad to enjoy the dance. They however inform Teacher Rascal and Principal that Riiya is being taken care of by the nurse. They soon realize that the school has no nurse and is now being haunted by a Nighting Ghost, a group of ghosts who "take care" of their patients, causing more pain and illness to worsen according to legend. They eventually rescue Riiya but discover that the ghost means no harm; in fact, she cured Riiya. Much to Shiine's dismay, Riiya gets to dance with Chacha all night, leaving no dance for Shiine alone with Chacha.
