The following light novel label will be added soon:
Shueisha Orange Bunko
An entertainment novel label that's aimed at women, and focuses on fantasy, mystery, science fiction, romance, romantic comedy, ... The label specializes in "light literature" and "character novel", and its keywords are "charming hero", and "immersive feeling to the story". It started on January 20th, 2015 with the release of five light novel volumes.
Circulation: 2015/01 - ?
This is also another label that lies somewhere between a novel label and a light novel label.
Other similar labels that lie somewhere in that area are:
Asahi Aero Bunko
Media Works Bunko
Fujimi L Bunko
Shincho Bunko nex
Though aimed at females, but there's no mention what age group it targets. Possibly women in their twenties and above...
Lately there seems to be an increase in two type of labels, one publishes novels that lie between general novels and light novels, and the second publishes light novels based on web novels that were originally serialized in the "Shousetsuka ni Narou" website.
