The story

Nippon Ichi Software was founded in September 1991 in Gifu Prefecture, Japan, as an entertainment software company. It was relocated and reincorporated on July 12, 1993. The company has made several acquisitions, mergers, and forming new subsidiaries. In the early 2010s, the company formed Nippon Ichi Software Asia Pte. Ltd and Nippon Ichi Software Vietnam Co., Ltd. In 2016, NIS merged with System Prisma Corporation and acquired developer FOG Inc. In 2012, the company was awarded the Guinness World Record for being the company that released the most strategy RPGs. The company assisted Hamster Corporation on their release of the Arcade Archives series in 2014, eventually dropping out as the series gained financial success.

The company has developed a number of traditional role-playing video games. Many characters from previous games make their way into later games as secret characters, even though their respective games may not be directly connected. Their flagship franchise, Disgaea, takes place in the same universe.
