In the year 2006, vocalist Hirocky and guitarist SDG#J met each other when they were working on the same omnibus. However, both their bands disbanded so they decided to try collaboration together at the studio.TAKA, a friend of SDG#J, promised to be the drummer of the new band. The band was now ready for lives and they started touring the clubs of Kansai since summer 2005.
Highly encouraged from the success of their first tour, DiabolosRadio decided to record a demo. In the beginning of 2006, two demos reached the rankings on a Japanese 'Internet playlist Top 10'. At the same time, the band started to work on their promotional DVD. They also started to think about forming their own label since the band had decided to hold artistic freedom rather than signing onto an existing label. DiabolosRadio soon formed Samurai Force Records, under which they would release their debut album.
The line-up experienced some changes with the addition of drummer NEOKI-SUN, who was a friend from SDG#J's other band, and DiabolosRadio was able to start recording their first album. In the springtime, they continued making their DVD and at that time AKIRA joined the band as a 'tour support member'.
While making their debut album, the newly recorded material, which at the time was only absent the drums before it could be finalized, went missing. The band was forced to record their music again in a hurry. Nevertheless, the recording machine equipment decided to break down so the completion of the album was delayed. DiabolosRadio, though, was satisfied with the re-run after all. Japan Needs a Hero! was released on 29th September and they went on tour to promote it.
By 2007, the band was struck with more problems, when AKIRA announced he would be leaving the band. Without a bassist, the three man band continued to perform live throughout the next two years, and in 2008 released Still Japan Needs a Hero!, sans bassist.
In late 2008, due to unforeseen circumstances, Hirocky left the band. DiabolosRadio chose not to go on hiatus, and instead simply experienced low activity over the next two years, with only fourteen shows in 2009 and no recording activity. In June 2010, SDG#J started the solo project under the name Jui, holding a number of shows.
Later that summer, Hirocky returned to the band and DiabolosRadio has resumed activities. In November 2010, released their two albums for sale on iTunes. In 2011, shortly after the Tohoku earthquake, DiabolosRadio announced they would be giving 100% of all profits from iTunes from mid-March until the end of April to a fund to help earthquake relief.
While the band is still a little quiet this year, fans can be sure they will see the band back in action soon.
