"hΨ=0", 2003.
Brain Hacker formed in 2002. Before even releasing any material, the group had its first lineup change when drummer Masashi left. He was never officially replaced, although Brain Hacker went on, and in August of 2003, Brain Hacker released its first full length album, "hΨ=0", and later released their first single, "Coin", that December. In July of 2004, Brain Hacker released its first mini-album "Tsunagareta Hitomi no Naka no Kioku (繋がれた瞳の中の記憶)", although it was a total flop in the visual underground, and can be tricky to obtain a copy of today as a result. "hΨ=0", on the other hand, proved to sell modestly well, and the group then rereleased it in November of 2004, alongside the release of their second mini-album "Dokkiri Horror Show (ドッキリホラーショー)", which was released on the same day as the repressing. Both the second press of "hΨ=0" and "Dokkiri Horror Show" had decent sales, and it seemed that Brain Hacker's luck was starting to turn in their favor. Despite their following growing substantially by the end of 2004, Brain Hacker slowed down their activities in 2005, performing only a bit of that year, and even less in 2006, before unsurprisingly announcing their disbandment in late 2006. Brain Hacker performed their final live in January of 2007, and officially disbanded afterwards. All of the members of Brain Hacker then immediately went on to form Art Cube, which fared much better in the visual underground than Brain Hacker, and actually became one of the most popular visual groups of their time, before eventually disbanding in 2015. After Art Cube split, the only member who remained active in the visual scene was frontman Seiji, who went on to refocus his attention as the frontman for the monstrously popular visual group Moi dix Mois, which he was active as under the alias of Seth, and also formed another group, Shape Shifter, under his original alias of Seiji. When Shape Shifter also split in 2017, Seiji then remained active as the frontman of Moi dix Mois, and also formed his own solo project, both of which he is still active in today.
