Nitroplus Co., Ltd. (nitro+) is a Japanese game company specializing in
Eroge Visual Novels. Its works are almost invariably
dark-themed, with an abundance of
Eldritch Abominations, horror, rape,
gore and violence.
They first came to general attention with the release of
Phantom Of Inferno in 2000, which also was main writer Gen Urobuchi's first released work with the company. Since then it has become well recognized in visual novel circles, such as the releases of
Saya no Uta in 2003 and
Chaos Head in 2008, along with
Key Visual Arts,
TYPE MOON and
07th Expansion. Another note, is that their music producer, Shingo Minamino, was murdered tragically, and brutally in the middle of a busy street.
Gen Urobuchi is one of the most prolific people in the company, as shown in the original light novel for
Fate/Zero and their widely famous
Puella Magi Madoka Magica, Nitroplus' second original anime. They also work with
Kanako Itou, who has perfomed most of the musical themes for their VNs or its adaptations.
