Vermillia originally is gothic rock band. but because unconsistence band member, keyboardist and song writer on this band,  wirarama take it as a his solo project. In early work untill unreal morning album  all song created digitally via computer without any vocal and instrument except keyboard and electric guitar. Other instrument was replaced by his keyboard and computer software. But after under the frozen rain, waiting for a rainbow album, music music is 80% by live recording and use a real bass guitar to make more natural progressive beat. The genre was moved to be instrumental industrial rock with little gothic influence. But in under the frozen rain, waiting for a rainbow album genre is back again to vermillia musical root as gothic rock but still as solo project. no old member included.

For solo project, themes of most vermillia song is a about loneliness, frustration, girl and stroker's feeling. But when still a band music themes is a heavy social issues like a religion, death, hell, abortion, sin etc.

Vermillia band version is planned to upload after have been re-arranged.
