Piece of Wonder is a hybrid tactical RPG and visual novel originally published in Japan in February 2002 by Studio Crossfire and released on January 21, 2007, in the United States by Hirameki International.

The game follows the experiences of high school student Kazuya Fuwa.

Most of the gameplay in Piece of Wonder follows the style of most visual novels; the majority of time spent playing the game is spent on reading through the dialogue or story that appears on screen.

The plot will then branch into paths focusing on a single heroine depending on the choices that were made by the player; a conclusive character ending will be presented at the end of any given path.

Played in classic RPG-style, the player takes control of the main characters and must accomplish a certain objective (usually to destroy all enemies on screen).
