Heavy pop and J-rock execute a cheerful system breach as Adust Rain upload Happy Hacker (Adust Rain ver). Composer kissssy originally wrote the track for Hokkaido idol group NooNico, but this self-cover drags the source code back into Adust Rain’s own metal-meets-pop laboratory—where sugary hooks are routinely given suspiciously large guitar processors and the distortion settings require administrator privileges.
Officially categorized as J-Pop and rock, the single offers a mischievous collision of idol brightness and heavier digital muscle: less malicious cyberattack, more unauthorized access to the brain’s chorus-storage partition. It was released as a one-track digital single on August 1, 2026.
