Picture	Real Name	Description
	Naoto Ooizumi	17 year old script writer of the CosPrayers children's TV show, although only the producer is aware of this. He's a lucky guy that's surrounded by five young girls - at work and at school. He always manages to get into "weird" situations with the girls. He starts to develop feelings for the main heroine of the show, Natsumi Yagami and it's mostly his relationship to her and the others that we get to vitness.
	Natsumi Yagami	She's the same age as Naoto and is starring in the CosPrayers show as the main Heroine (Miko Red Rayer). She believes that the only reason that she got the part was because of her looks and thus, underestimate her acting skills.
	Youko Katsugari	Same age as Naoto and plays the part of Sister Blue Rayer in the CosPrayers show. She's the opposite of Natsumi (which she consider as a rival). She's confident about her acting skills but not about her looks.
	Jougasaki Hikaru	A 14 year old tomboy due to growing up with 9 older brothers. Plays the part of Sari Yellow Rayer.
	Inamura Sayaka	She plays the part of Rabian Purple Rayer. She's the same age as Jougasaki, however her height and repetive childish behaviour makes people believe that she's younger than she is. She's quite skilled at imitating voices.
	Hayasaka Miku	the youngest memeber of the cast at an age of 11, she plays the part of Dian Green Rayer. She's very afraid of heights which frequently causes problem at the shoot.
