JDEU

The JDEU or J'deu (Japanese Demon Eradication Unit) is Japan's primary defence force against the Akuma onslaught. The JDEU is comprised mostly of former Japanese Self-Defence Force (JSDF) members, as the Japanese military reformed itself to primarily focus on Akuma attacks. The JDEU is currently lead by General Shohei Yoshida (吉田・翔平).

Foundation
The JDEU was officially founded in 2006, although its creation was heavily considered after the Paris Event in 2003; funding was slowly drained around 2005 and increased again around 2018. Initially, the JDEU was planned to simply be an elite unit (hence the name) and later became its own service branch. The branch finally merged the entire Japanese government in 2025, several months before the 2026 Akuma invasion. At the time it was mainly comprised of highly-trained JSDF combatants, while the rest of the JSDF was undergoing a major transformation to focus on effectively combatting the approaching Akuma presence. The Japanese government searched through the JSDF's ranks for the best soldiers or those with any Akuma experience in an excruciatingly long and thorough process to form the JDEU, which took a total of two years to properly complete.

Organisation
The Minister and Japanese Ministry of Defence (often called The Ministry) are at the top of the JDEU's chain of command, with the Minister being constantly informed by the Ministry. Military authority runs through the Ministry, with approval required by the Minister. After 2025, the JDEU essentially became the new Japanese government, so all power runs through the Minister and the Ministry, as well as succeeding departments.

Until 2024, both the Minister and the Ministry were advised by the Japanese Chief of Staff, Joint Staff (Nishioka Masayuki at the time), but the Minister convinced Mr Masayuki to reroute his military control to the Ministry as well as the Minister himself.
