Alice Soft

Alice Soft (also known as AliceSoft) was established in 1989, as an eroge publisher for the computer market, first for the PC-88 and PC-98, and later for PCs running Microsoft Windows platforms. Its first titles were Rance and Intruder, released simultaneously in July 1989. It has continued to release several titles each year, though not always exclusively adult-oriented.

The company's official mascot is Alice Chan, as well as the Hanny.

It is a brand name owned by Champion Soft Business Corporation (株式会社チャンピオンソフト).
