Shiho Nagaoka

Bright, outgoing, and always energetic, Shiho is Akari's best friend. She prides herself on her karaoke skills, and keeping everyone up to date with her special brand of gossip, Shiho-chan's News.

Shiho gets along with Akari and Masahi wonderfully; however, she and Hiroyuki are always butting heads over something.
