C's Ware is a label of HimeyaSoft Inc. (not to be confused with their US-Distribution arm Himeya Soft Inc.) from Tokyo, Japan developing complex and mature story-driven interactive visual novel adventure games, such as Desire, EVE Burst Error, and Glo-Ri-A.

Desire, Xenon and EVE Burst Error were produced by Hiroyuki Kanno, while their chiptune soundtracks were composed by Ryu Umemoto; both Kanno and Umemoto also worked on ELF's YU-NO: A girl who chants love at the bound of this world (1996). Kanno and Umemoto both died in 2011.

Some of the C's Ware games:

One of C's Ware's most notable visual novel games was EVE Burst Error (1995), written and produced by Hiroyuki Kanno and with chiptune video game music composed by Ryu Umemoto. The game featured a branching narrative where two different protagonists, one male and one female, provide different perspectives on the story. The game introduced a unique twist to the system by allowing the player to switch between both protagonists at any time during the game, instead of finishing one protagonist's scenario before playing the other. EVE Burst Error often requires the player to have both protagonists co-operate with each other at various points during the game.^[1] The use of multiple perspectives was since used in a number of later visual novels, such as Fate/stay night (2004),^[2] Machi (1998), and 428: Shibuya Scramble (2008). A somewhat similar character-switching system was also earlier used in Shin Onigashima (1987).
