KiriKiri(吉里吉里?) is a scriptingengine by Japanese developer "W.Dee". It is almost exclusively used with the KAG (KiriKiri Adventure Game System) framework to produce visual novels. Usually, the package of the two components is regarded as the whole engine, and referenced with major version numbers. Thus, the current version is called KiriKiri2/KAG3. It is available under the GNU General Public License, though commercial licenses can be acquired if somebody wishes to expand the software without disclosing the changes.
