Titles that are dismal or gloomy in nature qualify for the dark category.
Self-explanatory. Elementary school (class 1 to 6 in Japan) should play a major role in the title. Alien Nine is an example of this category.
Titles that contain characters who suffer from depression would fall into this category if this is of significant importance for the storyline.

 Narutaru ~Mukuro naru hoshi Tama taru ko~ |
Rent | While on a summer vacation at her grandparent's island residence, Tamai Shiina discovers a strange creature in the shape of a star. She discovers it is a ryu (a dragon). She names it Hoshimaru and returns home with it. Hoshimaru has many abilities including the power to fly, allowing Shiina-chan to "air surf" from time-to-time. He mimics a backpack so that Shiina can carry him everywhere she goes. |
