Team Shinku

King Empty Jay's Army or KEJA (pronounced kay-juh) for short, is a group of griefers known for launching cyber attacks on Drillimation Online communities. While the group of hackers are known for their disruptions, they have been a huge menace to Drillimation Studios since the launch of Drillimation Online in 1996.

Their raids have also been posted to YouTube, and their methods of attack ranges from trolling a group or individual to the manipulation of Drilliscript, the Driller Engine scripting language, where they perform such activities as showering their targets with boxes covered in internet memes and shock images. These boxes then produce storms of graphical particles that block the victim's vision. They have also created avatars similar to those of the residents being harassed and destroyed them in gruesome ways to simulate a virtual death.

Many of KEJA's hacks have been patched by Drillimation Studios.

History
The origin of the KEJA raids began after the official launch of the third version of the Driller Engine game engine, Driller Engine 3, and Drillimation Online in 1996.

Kantai Collection raids
In 2003, Drillimation launched the MMO strategy game Kantai Collection. In January 2005, KEJA hackers from China found out that a popular KanColle server was seized. As a result, KEJA hackers anonymously signed up for the site and used hacks during battles associated with the game. Many of the raiders who took part were device-banned and Drillimation patched the hacks the KEJA hackers used.
