[Hal-cioЙ] (ハルシオン) forms.
Second guitarist Airu (藍琉) was specifically listed on the band's OHP as “ex-秘密;” that is, the band made a point of mentioning that he was in some band, but not which.
According to 2ch, Airu (藍琉) was the same person as ex-Panic Channel (パニックちゃんねる) drummer Takumi (匠). Unfortunately, attendees of the band's first live reported that Airu (藍琉) purposely kept his head turned away from the audience to avoid being identified.
Despite having apparently been aware of the 2ch rumors, the band never addressed them. It's still unclear whether the widely-believed rumor was true, or if it was an elaborate publicity stunt by the band.
